Answer:
Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the tRNA anticodon and is congruent with what was actually found by researchers.
Explanation:
A group of researchers led by Seymour Benzer demonstrated that the anticodon of the charged tRNA was recognized by the protein synthesis machinery, when they changed the amino acid sequence. This example shows the exact result as found by the researchers.

Podemos suponer que este estudiante tiene insuficiencia de la hormona ____________________que la secreta la glándula _____________y se encuentra en la ___________. Esta hormona no ingresa a las células en su mecanismo de acción por ser __________________.
Answer:
Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.
Explanation:
En este caso presentado se encuentra una situación diferente a lo que sucede en el gigantismo: hay un problema hormonal en donde la hormona de crecimiento es secretada de manera excesiva. Recibe el nombre de acromegalia cuando sucede después del cierre de la epífisis del hueso, luego de la edad de crecimiento.
Which type of microscope would be the best tool to use to view the surface of a bacterial cell? Why?
Answer:
Electron Microscope
Explanation:
The maximum theoretical resolution of images created by light microscopes is ultimately limited by the wavelengths of visible light. Most light microscopes can only magnify 1000×, and a few can magnify up to 1500×, but this does not begin to approach the magnifying power of an electron microscope (EM), which uses short-wavelength electron beams rather than light to increase magnification and resolution.
-The electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
An Electron microscope is the type of microscope that would be the best tool to use to view the surface of a bacterial cell.
What is a Microscope?A microscope may be defined as an instrument that utilizes the arrangements of lenses to make an enlarged image of a small object.
An Electron microscope produces a higher resolution of bacterial cells as compared to a standard light microscope. This is because electrons possess a much shorter wavelength than visible light.
Therefore, the correct answer to this question is an Electron microscope.

Light microscopeElectron microscope.Fluorescence microscopes.The incidence of phenylketonuria (PKU), an autosomal recessive genetic disorder, is approximately 1 in 4,500 in Ireland. Assuming Hardy-Weinberg equilibrium, what is the probability that an Irish female, who is phenotypically normal with no family history of PKU, and an Irish male, who like his parents does not have PKU, but does have a sister with PKU, will have a child with PKU?
Answer: Probability: 0%
Explanation:
Hardy-Weinberg establishes that the genetic composition of a population remains in equilibrium as long as no natural selection or other factors act and no mutations occur. This means that the children of this couple will inherit the genes of the parents.
The woman is phenotypically normal with no family history of PKU, this mean that probably there are no affected (recessive) alleles in her family. In an autosomal recessive disorder, both copies of the gene in each cell are recessive. Therefore, her genotype will be AA with A being the dominant and normal allele. As for the Irish man, his sister does have PKU, which means her genotype is aa. So, she must have received a defective allele from each parent. Then the parents' genotypes are both Aa (heterozygous, only one allele affected as they are healthy). So, we know that the Irish man does not have the disease (he can't be aa), but he could be Aa (having inherited a normal allele from one parent, and an affected one from the other parent) or AA (having inherited both normal alleles from each parent).
Then we have two possible punnetts square to do: AA (the Irish woman) and AA (he Irish man); or AA (woman) and Aa (man).
In the attached figure both punnetts squares are shown. The first punnett square (AA x AA) shows that 100% of the offspring will be AA (this means, the phenotypic ratio is also 100% not affected and non-carrier). The second punnett square (AA x Aa) shows that 50% will be AA (healthy and non-carrier) and 50% will be Aa (heterozygous, healthy and carrier) But since it is an autosomal recessive disease, a single affected allele is not enough to develop the disease. So in neither case is there a chance of having a child with PKU.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis, a generally mild but potentially fatal disease, especially in cats and human fetuses. Cats and other felines are considered their ultimate hosts because the sexed phase of their life cycle takes place there, making these animals the primary hosts of the parasite. The asexual phase of the life cycle can occur in any warm-blooded animal, such as other mammals and birds. Therefore, toxoplasmosis is a parasitic zoonosis.
Parasites invade the cells, forming a compartment called the parasitophore vacuole which form cysts in tissues, especially in the muscles and brain. Because the parasite is inside the cells, the host immune system does not detect these cysts. Antibiotic resistance varies, but cysts are difficult to eradicate entirely. Therefore, T. gondii spreads within these vacuoles through a series of binary divisions until the infested cell eventually breaks free.
Some people have flu-like signs and symptoms, which may be:
Swollen lymph nodesHeadacheFeverFatigueWidespread painIn people with impaired immune systems, symptoms may also include:
ConfusionLack of coordinationConvulsionsBlurred vision caused by intense swelling of the retinaIn recent years, several investigations indicate that the parasite can cause changes in the behavior associated with impulsivity, and personality disorders. So, we could predict it zombifies the host by changes in the behavior, because of the damage caused by a parasite in the brain. It is important to consider that the brain governs the body, and cysts found there can trigger these changes.
Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.
Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.

Which observation led Mendel to the idea that traits were controlled by more than a single factor? Crossing two purple-flowered pea plants always resulted in a purple-flowered pea plant. Crossing two white-flowered pea plants always resulted in a white-flowered pea plant. A trait that was not seen in the first generation may later reappear in the second generation. A trait that was not seen in the first generation was completely gone and never reappeared.
Answer:
The answer is option C.
Explanation:
Genetic traits are expressed by dominant and recessive genes, which show up in the phenotype according to their presence on the chromosomes.
Observing a trait that was not present in the previous generations suggests that this trait is recessive and did not have the chance to appear in the other generations before. This idea has led Mendel to the idea that traits were not controlled by only a single factor. So the answer is C.

The primary function of the lymphatic system is The primary function of the lymphatic system is the production and distribution of plasma proteins. the transport of hormones. the production and maturation of leukocytes. circulation of nutrients and dissolved gases. defending the body against both external and internal threats.
Answer:
The primary function of the lymphatic system is defending the body against both external and internal threats.
Explanation:
The set of tissues and organs that participate in the immune response is known as the lymphatic system. Its main functions are to maintain the volume of blood and participate in the defense of the organism. It is made up of organs, vessels, nodes and lymphatic tissue. This system fulfills three basic functions: Defense: in the lymph nodes, the lymphocytes reproduce to respond to antigens; fat absorption: most of the fats are absorbed by the lymphatic system and subsequently transported to the blood and capillary exchange: it recovers substances that the blood flow has lost in the capillary exchange.
The principal function of the lymphatic system is to remove strange or damaging substances from tissues and eliminate them. The correct option is defending the body against both external and internal threats.
------------------------------
Among other functions of the lymphatic system, its principal one is the removal of damaged cells, cancer cells, and protection of the body against the virus, bacteria, and fungi that might affect it.
The lymphatic system remove these elements from the tissues for their elimination.
All these strange microorganisms and waste substances get filtrated in the lymphatic ganglia.
Ganglia are small organs located all along with the net of lymphatic vessels, that function as lymph accumulation centers.
Lymph passes through these organs and gets filtrated and purified of waste substances.
Inside each ganglion, the lymphocytes T and lymphocytes B help the organism to fight these infections.
B cells produce antibodies that impede infection propagation by trapping the microorganisms and destroying them.
Most lymphatic ganglia are grouped near the neck, underarm, and groin.
They are also grouped in the chest, abdomen, and pelvis, where they filter blood.

Explanation:
All living things are composed of cells.
Cells are the basic units of structure and function for living things.
All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.
The three basic parts of the cell theory are:
All living things are made of cells.
Cells come from preexisting cells.
All cells have the same basic parts.
How do we explain?Cells are the basic unit of life. All living things, from the smallest bacteria to the largest redwood tree, are made up of cells.
Cells are not created spontaneously. All cells come from the division of preexisting cells.
Despite their great diversity, all cells have the same basic parts, including a plasma membrane, cytoplasm, and DNA.
The cell theory was first proposed by Matthias Schleiden and Theodor Schwann in the 1830s. It has since been supported by a vast body of evidence from cell biology. The cell theory is one of the most important and fundamental concepts in biology.

[tex] \bold{ \green {Scope \: of \: Environment \: education}}[/tex]
Environmental education includes the study of various factors of the environment which affect the health of human beings. Environment comprises all the factors in our surroundings. It includes even abstract factors , which do not have weight , length and breadth. Cultural traits , social norms and values, feasts and festivals etc. are some of the examples of abstract aspects. Some of the scopes of environment education are described below:
Physical aspect ( soil , water , air , rocks , gases etc )The physical aspect included non- living things on the earth. They are soil, water , air , rocks , gases etc. Environment education gives knowledge about the status of soil , water , air , rocks , gases and other various physical components of the earth. It aims to make students aware of the effects and consequences of human activities upon these factors. It also gives knowledge to raise environment friendly attitude and behavior among the students .
Biological aspect ( biology , agriculture , forestry etc )The biotics factors include living plants and animals , their life mechanism , interrelationship etc. Some of the educational streams related to the biotic aspects are biology , agriculture , and forestry. They are some of the important scopes of the environment education. This branch of education helps to develop the level of knowledge , attitude and behavior regarding these factors in the students.
Socio - cultural aspect ( sociology , civics , religion , ethnicity , anthropology etc )Environment has some of the abstract aspects too. Abstract aspects include religious , cultural , ethnic and social norms and values. Some of the educational streams dealing with this aspect are sociology , civics and anthropology. Environment education also teaches students about such abstract factors, which play vital role in the environment.
[tex] \bold{ \green{Scope \: of \: Health \: education}}[/tex]
In general , scope of health education can be understood as the areas included in health education. Health education not only communicates knowledge about body features and diseases, but also includes the matters concerned with healthy surroundings , human psychological states affecting health , public health, human anthropology , medical science and so many other things. Any three scopes of health education are as follows:
HomeHome is the residence of all people. Home is the first school for all. A child passes the primary days of life at home. Every individual learns the basic skills if survival at home. Proper time to wake up in the morning , to start daily sanitary schedules, to eat , to practise all other health behavior are learnt at home. The child lives in community and learns many more about healthy social adjustment in the social environment. Health education aims to raise the level of knowledge , attitude , and behavior related to health and healthy life.
SchoolChildren go to school for formal education and spend most of active hours of a day. They achieve several forms of health knowledge and develop healthy attitude and practise accordingly. Their heath status depends upon the environment of school , health curriculum, healthful school environment , co-curricular and extra - curricular health activities.
CommunityCommunity is a place where many people live with their families. People's health is determined by the several factors in the community. Health education teaches about these factors like community sanitation , drainage , health service providing organizations and health centers.
