The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.

Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).

This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.

CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.

For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.

Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".

The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.

What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

Answer:

You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.

A way through which geologists may utilize GPS and satellite mapping is to monitor the changes in the environment.

A global positioning system refers to a network of receiving devices and satellites that are used to determine the location of a particular thing on Earth.

It should be noted that a global positioning system (GPS) and satellite mapping can be used in monitoring changes in the environment. It can also be used to collect accurate field data when mapping or surveying.

Explanation:

Cercopithecine Herpes virus-1 (B-virus) pathogen poses the greatest risk to a researcher handling non-human primates if they are exposed and infected with the infectious agent.

pathogens are the biological agent that can cause a disease in another organism upon infecting and causes infectious diseases. ‘Pathogen’ is a or disease-causing organisms such as bacteria, viruses, fungi, protozoans and worms.

There are different types of pathogens such as Class 1 pathogen in which the species is not associated with infectious disease. Class 2 are the pathogen species cause disease in humans but not serious and the the preventive methods, treatments are available.

Class 3 pathogens include the species cause serious diseases in humans, but necessary prophylaxis and treatment are available; Class 4 pathogens include the species cause serious human disease and disseminate in the human population with  no adequate prophylaxis or therapy exists.

Given our understanding of the situation, we can confirm that the use of green or white light would not be ideal for the experiment at hand because it will not yield any useful information.

In this experiment, we wish to determine the dependence of specific color wavelengths on the rate of photosynthesis. The use of white light for this experiment will defeat the purpose, given that white is the naturally occurring color of light and the available data on this is vast.

Furthermore, we would not use green colored light because it will not be effective. The effectiveness of the color of light that we decide to use will be based on the absorption rate of the light at a cellular level. Green light is known to not be well absorbed by the chlorophyll of plants and therefore will not be useful.

Answer: Independent Variable

Explanation: Already explained this one in another post.

Smallest to Largest:

1. Nucleotide

2. Gene

3. Chromosome

4. Genome

Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

Chromosomes are the thread-like structure made up of protein (histones) and a single molecule of DNA which carries all the genetic information in it. It is located in nucleus.

Human have 23 pairs of chromosomes including pairs of 22 chromosomes (i.e. Autosomal Chromosomes) and 1 pair of Sex Chromosome (XX or XY).

Each pair contain two Chromosomes inheriting from the parents, half from mother and another half from the father.

Each chromosome have a point which is constricted in the middle known as Centromere, which divides chromosomes into two arms i.e. short arm “p” and long arm “q”.

Thus, Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

Explanation:

Answer: Narwhals, polar bears, and walruses will be affected the most.

Explanation:

Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.

Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.

Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.

Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".

The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.

Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

The homologous structure to the forearm of humans is the leg of the horse.

Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.

The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.
