Answer:
Because these circles have three factors that are directly interconnected.
Explanation:
As you know, communication is one of the primary factors for the creation and maintenance of societies. Societies grow and develop with communication as a starting point and a link between people and the actions that a society lives.
Science, in turn, is also directly influential in the creation and development of society, since it is a transforming factor that shapes society through its constant evolution.
As science evolves, society changes and communication must accompany these changes, so that both society and science continue to exist.
For this reason, we can say that the circle of communication results is linked to the circle called science and society, because these factors are directly interconnected.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6
Answer:
option A is correct that is 12
Explanation:
meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)
now 2n=24
n=24/2 =12
after meiosis stage 1...........two daughter cell each with 24 chromosomes
stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes
net result.......4 daughter cell each with 12 chromosome(assuming cell as a diploid cell)
If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.
The answer is option A.
What are meiotic and mitotic cell divisions?There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells. Meiosis is the sort of cell division that creates egg and sperm cells. Mitosis is an essential technique for lifestyles.

Vanessa attempts to freeze liquid mercury. Which statements describe particle arrangement and motion that occur in mercury?
Answer:
Volume of mercury decreases due to close arrangement of particles.
Explanation:
When we freeze liquid mercury, its volume decreases and density increases from from 13.69 g/cm3 to 14.184 g/cm3 and form a solid mercury. The motion of particles stop when we freezes liquid mercury and the particles settles into a stable arrangement. If we cool the liquid mercury and the temperature reaches to -38.83 °C, then it converts from liquid into solid substance.
The diagram summarizes the light-dependent reactions of photosynthesis. A diagram shows the light-dependent reactions of photosynthesis. x goes to the light dependent reaction. The light dependent reaction goes to chemical energy and oxygen. What is the input of the light-dependent reactions, labeled X? CO2, H2O, O2, and light CO2, H2O, and light CO2 and H2O H2O and light
Answer:
Although there is no diagram attached to this question but it can be answered based on the general knowledge of photosynthesis. The answer is:
H2O and light
Explanation:
Photosynthesis is a unique phenomenon that occurs in the Chloroplast of plant cells. It is the process by which plants and other autotrophs obtain their energy source (food) in the presence of sunlight. Photosynthetic process occurs in two distinct stages viz: light dependent reaction and light independent reactions.
The light dependent reaction, as the name implies, is dependent on light to occur. It occurs in the Thylakoid membrane of the Chloroplast, where a photon of light is captured by the Chlorophyll pigment and the energy is used to split molecule of water in a process called PHOTOLYSIS OF WATER. The transfer of electrons across the thylakoid membrane creates a proton pump, which is used to generate ATP and NADPH. NADPH and ATP are electron and energy carriers respectively which enters into the light independent stage in order to synthesize glucose (sugar).
In a nutshell, the inputs of the light dependent stage are LIGHT from the sun, and water (H2O), which provides the proton and electron when split.

2. Explain the factors that led Wilson to the idea of (a) studying small islets, (b) fumigating them, and (c) observing the recolonization of species.
Answer and Explanation:
The ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could be inhabiting on an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance from the mainland and the size of the island.
At the same time, these factors affect inmigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.
Experiment:
To prove that the observations about the species richness and its relation to island size and distance to the continent were not a casualty, manipulation experiments were developed. These experiments helped to prove how the colonization process take place from cero. To observe the entire process of ecological succession and the tendencies proposed by the island biogeography theory Wilson and Simberloff (1970) eliminated the fauna on some islands to observe how they were recolonized from the continent. They fumigated the mangler island and studied these islands to account for the variation in arthropod richness over time. They studied many islands classified by distance. On each island, the richness increased at different rates. The island closest to the continent received more immigrants and is colonized faster than the other ones, reaching its original richness faster. The farthest island was recolonized but at a much lower rate and it does not reach equilibrium while the study was going on. Although, it was expected to reach equilibrium with time.

Scientists are able to reproduce certain plants and animals by cloning them in laboratories. The diagram shows the steps of cloning using tissue cultures. Do you think cloning is a form of asexual reproduction? Explain your answer using evidence from the diagram
Answer:
Yes.
Explanation:
Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.
Answer:
Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

When objects of two different temperature are in contact, what happens?
Answer:
The answer is C.
Explanation:
This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.
What change in temperature when object are in contact?It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.
Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.
The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.
Therefore, The warmer object transfer heat energy to the cooler object.

Algae in the genus Caulerpa typically grow to a length of over half a meter and have structures similar to stems,leaves,and roots.Reproduction occurs when adults produce sperm and eggs that fuse to form offspring.Each adult Caulerpa consists of just a single cell,however.Which of the following statements is true?
A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.
Answer:
D) The existence of Caulerpa is consistent with the cell theory.
Explanation:
This question describes species of algae in the genus, Caulerpa, which is a unicellular organism that possesses structures similar to leaves, stems and roots in plants. It also grows to a length of about 0.5metres. it reproduces sexually by fertilization of gametes (sperm and egg).
According to all these described characteristics of Caulerpa, it's existence is in conformity or accordance with the unified cell theory, which was proposed by three scientists namely: Matthias Scleiden, Theodor Schwann, and Rudolf Virchow in the 1830's. The three components of the cell theory states that:
1. Cell is the fundamental and basic unit of life existence.
2. All living organisms are composed of one (unicellular) or more cells (multicellular).
3. All cells come from already preexisting cells.
Hence, based on the components of the cell theory and the life pattern of Caulerpa i.e. Caulerpa is made up of one cell, it is made from the fusion of preexisting parental cells etc. It is consistent with the cell theory.

What has a greater influence on protein levels? A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from
Answer: b
Explanation: i got the answer wrong and i’m looking at the results rn
Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.
The cause of the greater influence of protein levels has defined as follows:
The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.
Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

During the 1950s, a scientist named Lysenko tried to solve the food shortages in the Soviet Union by breeding wheat that could grow in Siberia. He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring. Based on the ideas of artificial and natural selection, do you think this project worked as planned
Answer:
No
Explanation:
Trofim Lysenko was a Biologist in the then Soviet Union, who did not believe in the fundamental laws of science. Selective breeding is the method developed by humans to change certain characteristics of species to desired outcomes. This is based on the fact that living things have inheritable traits encoded in genes that can be passed from one generation to another.
Lysenko did not believe in this fact. He rather believed that when exposed to the right environment, plants and animals soon become adjusted to the exposure and can then develop traits that would be passed on to their offsprings. He applied this theory of his when he exposed wheat plants to cold believing that they would develop tolerance to cold. This failed woefully and resulted in severe starvation that caused the death of millions of people in the Soviet Union.

Nitrogenous bases are used to construct nucleotides. Until the discovery of the helical shape of the DNA molecule, were only possible to identify the genetic material (chromosomes) by the microscope. Chromosomes are composed of DNA and proteins (histones). Nucleotides are the building blocks of the DNA molecule. The X-ray diffraction data obtained by Rosalind Franklin were used to decipher the DNA structure. The ball-and-stick is a molecular model where atoms are represented by spheres and bonds are represented by rods. Chargaff's rules indicate that the content of cytosine is equal to guanine and adenine is equal to thymine. Rosalind Franklin died of ovarian cancer in 1958. The double-stranded DNA molecule must be unwound and then the DNA strands serve as templates to synthesize identical DNA molecules.
