Answer 1

Answer:

Vasoconstriction is the opposite of vasodilation. While vasodilation is the widening of your blood vessels, vasoconstriction is the narrowing of blood vessels. It's due to a contraction of muscles in the blood vessels. When vasoconstriction occurs, the blood flow to some of your body's tissues becomes restricted

Homeostasis is the maintenance of a stable internal environment.

What type of selection occurs when individuals
with traits at either extreme have higher
fitness than those individuals in the middle?
A. directional
B. stabilizing
C. disruptive

Answers

Disruptive type of selection occurs when individuals with traits at either extreme have higher fitness than those individuals in the middle. Hence option c is correct.

Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype.

When those at the upper and lower extremities of the curve are more fit than people in the middle, disruptive selection takes place. Disruptive selection targets people of an intermediate type, and it can result in the emergence of two different phenotypes.

African seed cracker birds' various beak sizes show evidence of disruptive selection. The beaks of the birds vary in size, and they eat seeds. There were two different sizes of seeds available: tiny and large.

If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?

Answers

Answer:

U A A G C U G A G C

Explanation:

The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).

But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).

Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:

A T T C G A C T C G

Translate:

U A A G C U G A G C

So, the complementary mRNA sequence will be U A A G C U G A G C

Which motion of particles across a membrane requires energy?
from high concentration to low concentration
from low concentration to high concentration
with no concentration gradient
through dynamic equilibrium

Answers

Answer:

B

Explanation:

Edge 2021

The motion of particles across a membrane from low concentration to high concentration requires energy. This process is called active transport. So, the correct option is B.

What is Active transport?

Active transport, which requires energy in the form of ATP (adenosine triphosphate) or another energy source, is the movement of particles or molecules across a membrane from a region of low concentration to an area of high concentration, against the concentration gradient.

Numerous cellular functions, including the absorption of nutrients and the elimination of waste materials, depend on this mechanism. The sodium-potassium pump and the proton pump are two examples of active transport since they both employ ATP to move ions across cell membranes.

Therefore, the correct option is B.

Answer:

Nonpolar side chains of amino acids tend to associate to form hydrophobic clusters usually away from the protein surface.

Explanation:

Hydrophobic interactions are defined as the relationship between the low water soluble molecules named hydrophobes and water. They contains a long chain of carbon atoms and are usually considered as a nonpolar molecules.

They occur when the non polar amino acids are associated to produce the hydrophobic clusters that are usually away from the surface of the protein.

True or False: As ATP is used in the myofilaments, mitochondrion, and cytoplasm of muscle cells, heat is released. The circulatory system takes heat to the skin’s surface to dissipate to the environment. People sweat to help cool down.

Answers

Answer:

- As ATP is used in the myofilaments, mitochondrion, and cytoplasm of muscle cells, heat is released. True

- The circulatory system takes heat to the skin’s surface to dissipate to the environment. True

- People sweat to help cool down. True

Explanation:

Muscle contraction occurs when myosin heads bind to actin to pull it inwards. The energy for muscle contraction is provided by the hydrolysis of ATP molecules. ATP hydrolysis also provides energy for cellular processes in the mitochondria and cytoplasm of muscle cells. During ATP hydrolysis, heat is released, thereby the increase in ATP hydrolysis increases heat production (approx. 60% of the energy released from ATP hydrolysis produces metabolic heat). Moreover, on hot days, the cardiovascular system composed of the heart and blood vessels dissipates heat through the blood flowing in veins and arteries, which moves closer to the skin surface (and therefore heat is lost). Finally, sweating refers to the process of exocrine secretion of the sweat glands that release salty water through the pores of the skin. As sweat evaporates, it helps to cool down the body and regulate its temperature.

Explica como crees que se originó la vida sobre el planeta tierra

Answers

Sabemos que la vida comenzó hace al menos 3.500 millones de años, porque esa es la edad de las rocas más antiguas con evidencia fósil de vida en la tierra. Estas rocas son raras porque los procesos geológicos posteriores han remodelado la superficie de nuestro planeta, a menudo destruyendo rocas más viejas y creando otras nuevas (lo siento si es un amor incorrecto, marque como más inteligente si es correcto).
La pregunta del cómo empezó la vida en la Tierra es una de las más difíciles (e interesantes) que se pueden plantear. De hecho, el origen de los seres vivos encierra varias cuestiones clave: ¿cuándo ocurrió?, ¿pudo producirse más de una vez?, ¿cómo fue la transición entre la química y la biología?, ¿tuvo lugar en la Tierra o fuera de ella? Y, a medio camino entre la ciencia y la filosofía: ¿fue fruto del azar o de la necesidad?

La investigación experimental sobre el origen de la vida comenzó en la década de 1950, con el trabajo de dos científicos pioneros en una disciplina llamada química prebiótica: Stanley L. Miller y Joan Oró. Las pruebas acumuladas desde entonces nos indican que la vida probablemente comenzó hace unos 3.800 millones de años, sólo 700 millones de años después de la formación de nuestro planeta. En el gran laboratorio de química que era la Tierra primitiva se sintetizaron las primeras moléculas orgánicas, que fueron organizándose progresivamente para formar otras más largas y complejas.

d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.

Answers

The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.  

Explanation  

Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.

In an animal, which part of the cell is responsible for keeping viruses out?

Answers

Answer:

here's your answer

Explanation:

Once attached to a host cell, animal viruses may enter in a variety of ways: by endocytosis, where the membrane folds in; by making channels in the host membrane (through which DNA or RNA can be injected); or, for enveloped viruses, by fusing with the membrane and releasing the capsid inside of the cell.

In an animal cell, the lysosome is an organelle of the cell that is responsible for destroying the virus. The virus can enter the cell via endocytosis, but the lysosome can degrade and destroy it to protect the cell.

What is the function of the immune cell?

Immune cells such as neutrophils, macrophages, and others play a role in protecting the body from foreign harmful pathogens. They have specific structures for doing so.

Because not all body cells have MHC II or toll-like receptors, cells have different organelles to protect themselves. Cells have lysosomes within them. Lysosomes have an acidic environment that can degrade viral proteins.

When the virus is phagocytosed by the cell, it combines with the lysosome. The lysosome degrades the virus with the help of hydrolyzing enzymes and throws it out of the cells. These are collected by other cells.

Hence, the lysosome of the cell degrades the virus and keeps it out.

A study is done on a group of families in Sweden that are segregating a genetic disorder. A statistical estimate of whether two genes, or a gene and a disease gene, are likely to be located near each other on a chromosome (called Lod-score analysis) indicates that the gene involved in the disorder shows a strong likelihood of linkage with a particular DNA marker locus. However, a second study done in Italy with other families segregating the same genetic disorder results in lod-score values that strongly indicate the lack of linkage between the gene and the same DNA marker locus. Assuming that both studies were performed appropriately, what is the most likely explanation for the different outcomes

Answers

Answer:

This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.

Explanation:

A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one locus that is associated with the disease phenotype. However, in the second study, a second locus that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).
