During which phases of the cell cycle are chromosomes composed of two chromatids?
Answers
Answer:
The correct phases are S phase, prophase, anaphase.
Explanation:
The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.

(50pts) The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light coloration. However, because of widespread pollution during the Industrial Revolution in England, the dark colored moths became much more common.
Question:
What specifically caused the shift in phenotype of the moths? Please explain in detail.
Answers
Answer:
The peppered moth is a temperate species of night-flying moth. Peppered moth evolution is an example of population genetics and natural selection and not artificial selection.
Explanation:
Answer:
The phenotype of the moth changed due to natural selection. During the Industrial Revolution, objects in England became a lot darker in color due to the settling of coal pollutants in the air. These light colored moths did not have good camouflage in this environment. Therefore, most of the light colored moths did not survive to reproduce. However, the dark colored moths had better camouflage, and were therefore more likely to survive and reproduce. This lead to a shift towards darker color moths, as they had a higher survival rate than the light colored moths.
choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
Answers
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

Humans often like to help wild animals. A marine biologist near the area where Anchor’s offspring are located has decided to feed them. He begins putting medicine in the food that keeps the pups from contracting infections common to sharks in the area. Because of this, nearly all of Anchor’s offspring survive to adulthood. Eventually, the marine biologist gets a job transfer and leaves the area. Predict what we may see in the following generation (Anchor’s grandpops). Will they still be fitter than other sharks?
Answers
Answer:
I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.
This question seems like its asking about natural selection.
"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"
Explanation:
If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes.
The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die.

Describe how the process of apoptosis occurs?
Answers
Answer:
Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
What is apoptosis ?It is a natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.
There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.
Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.
Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated Bax, and Bcl-2 molecules.
Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

Where does the mRNA go after it is produced?
Answers
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.

Restriction enzyme is use to cut DNA into smaller fragments by preventing the replication of the phage DNA .
Restriction enzyme is use when there is infection or foreign materials that intrude into a bacterium,the bacterium uses it to defend itself against infections that might be cause by viruses, pathogens e.t.c.
