The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Explanation:

The protein domain of STAT3, which is not expected to play a role in STAT3 signaling, is the signal sequence domain. Correct answer: letter B.

The signal sequence domain of STAT3 is a protein domain that is not expected to play a role in STAT3 signaling. This domain is located at the amino-terminal end of the protein and is responsible for targeting STAT3 to the endoplasmic reticulum for further post-translational modification.

The signal sequence is a short hydrophobic region of about 20 amino acids that is recognized and bound by the SRP (signal recognition particle) receptor of the endoplasmic reticulum membrane. Once bound, the SRP receptor helps STAT3 to enter the endoplasmic reticulum, where it can be modified, folded, and transported to its eventual destination.

Answer: D. no natural selection

Explanation:

Fitness refers to the passing down of genetic make up based on the environmental requirements for reproduction and survival.

Answer choice A is incorrect, as large population, refers to the fact the more individuals in the population, the smaller effect of genetic drift. Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Answer choice B is incorrect, as random mating, refers to each individuals in a population have the same chance of passing on its alleles. An example of random mating includes: lions with darker fur color have the same chance to reproduce as lions with a lighter fur color.

Answer choice C is incorrect, as no mutations, refers to no changes to genes, new alleles are not introduced into the populations gene pool.

D is correct, no natural selection is when no phenotype can have a selective advantage over another - all individuals have equal fitness. And that correlates with the fitness being the same among all individuals in the population.

In a trophic chain, energy passes from one trophic level to the other. Foxes are omnivores. Grasshoppers, meadow voles and gray squirrels are herbivores. Muskrats, red fores and racoons are herbivores/carnivores. Crayfishes are herbivore/detritivores. Red clover, oak tree, and algae are Producers.

-----------------------

When talking about the trophic web, we refer to the energy transference from one organism to the other. These organisms place at different levels. Each level feeds on the anterior one and gets eaten by the next one.  

1) The first link is composed of organisms that take radiation energy to produce organic compounds. These are autotroph organisms or producers.

2) The following links are the consumers:

3) The last links are the decomposers, fungi, and microorganisms that act on dead animals degrading organic matter.  

Any change that occurs at any of the links will immediately affect the other links too. It will cause an increase or decrease in their population sizes.  

From the energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers. This small percentage of energy flows through all organisms in the ecosystem -from autotrophs to heterotrophs- until it dissipates in the environment.  

Only 10% of energy passes from one level to the next one. This assessment is called The 10% rule. It states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.  

The progressive reduction of energy determines the number of trophic levels (4 or 5).

Answer:

Yes, some cells are able to move on their own. This type of movement is known as cell motility, and it is a crucial aspect of many biological processes, such as embryonic development, wound healing, and immune response.

There are different mechanisms by which cells can move. Some cells, such as bacteria and sperm cells, have flagella or cilia that allow them to swim or move through fluids. Other cells, such as white blood cells, use a process called amoeboid motion, where they extend and retract membrane protrusions to move forward.

In addition, some cells are able to migrate through tissues and organs by sensing and responding to chemical cues in their environment. This type of movement is known as chemotaxis, and it allows cells to move towards or away from specific chemicals.

So, in summary, while not all cells are able to move on their own, many types of cells have the ability to move through various mechanisms.

In prokaryotes, the type of RNA that can and cannot be used are dependent on the function it serves.In prokaryotes, three types of RNA can be used whereas RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes.

Prokaryotes are unicellular organisms that do not have a nucleus or membrane-bound organelles. The genetic material is present in the cytoplasm and is arranged in a single, circular DNA molecule. As a result, the RNA transcription and translation occurs in the same location. As a result, there is no alternative splicing or post-transcriptional modification.

Hence, all RNAs are synthesized from a single, uninterrupted gene.In prokaryotes, three types of RNA can be used: Messenger RNA (mRNA) transcribes the genetic information from DNA, which is then translated into a protein. Ribosomal RNA (rRNA) is a major component of ribosomes and is essential for protein synthesis. Transfer RNA (tRNA) is a specialized RNA molecule that carries amino acids to the ribosome during translation. In prokaryotes, RNA that undergoes splicing, such as hnRNA or pre-mRNA, is not used.Eukaryotes are multicellular organisms that have a nucleus and membrane-bound organelles.

Eukaryotic cells have linear DNA arranged into chromosomes and are located in the nucleus. RNA transcription occurs in the nucleus, while translation occurs in the cytoplasm. Eukaryotes also have alternative splicing and post-transcriptional modification. So,RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes. Eukaryotes have five types of RNA that can be used: Messenger RNA (mRNA), Ribosomal RNA (rRNA), Transfer RNA (tRNA), Small nuclear RNA (snRNA), and Small nucleolar RNA (snoRNA).

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.

Women and noblemen,

Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.

Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.

Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.

Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.

In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.

Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.

To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.

In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.

In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

There are five postulates proposed by Darwin to explain the mechanism of natural selection.

- Individuals are variable (therefore, D is incorrect)

- More offspring is produced than can survive (so C is incorrect as well)

- The history of Earth is long

- Some variations are passed down (meaning that B is also wrong)

- Survival and reproduction are not random (so E is incorrect too).

The genetic drift is part of the theory of evolution proposed by Sewall Wright, not by Darwin. Therefore, the correct answer is A. Small populations can lead to genetic drift.

The shape of the active site in a given enzyme is determined by the amino acid residues of the protein and the interaction between such amino acids and also molecules in the physiological conditions of the surrounding media.

The active site in a given enzyme protein is the molecular domain in the enzyme that binds to the substrate in a chemical reaction in order to form the enzyme-substrate complex that will be converted into products. The shape of the active site in the protein enzyme also depends on the amino acids in the domain that binds to the substrate and also to the molecular interactions.

Therefore, with this data, we can see that the active site in a given enzyme protein is dependent on the amino acids in the protein and their interactions.
