The virus infections happens when a virus gets past the physical barriers of the body (skin, mucus, and so on) and infect a suitable cell, the virus take the genetic machinery of the host cell to replicate, damaging that cell and making more virus that will do the same process with other suitable cells. After the virus use all the cell potential, it will kill the cell and release all the virus that were in the cytoplasm of the host. While bacterial infections have more autonomy, being not necessary the integral machinery of the cell to multiply in the host body, it can act in differrebt ways, such as: crowd out the host tissue and disrupt the function, killing the cells or tissues outright, destroy the metabolic machinery, cause a massive toxic reaction in the immune system, and release toxins that can make the body stop all their functions at once (paralyze the metabolic and general system of the host).

An example of a primary producer is c. a diatom. Primary producers are organisms that produce organic compounds from inorganic substances through the process of photosynthesis or chemosynthesis.

They are the base of the food chain, as they provide energy to all other living organisms in an ecosystem. Diatoms are unicellular algae that are found in both freshwater and marine environments. They play a crucial role in the food chain, as they are the primary producers in many aquatic ecosystems. They are known for their ability to produce up to 20% of the oxygen on Earth, making them an essential part of the planet's ecosystem. In summary, diatoms are an excellent example of a primary producer because they play a vital role in the food chain and provide energy to other living organisms in aquatic ecosystems.

The cap structure or Capping protects coding sequences at the 5' end of mRNA from degradation.

The cap structure refers to a modified nucleotide structure added to the 5' end of eukaryotic mRNA molecules during transcription. It consists of a modified guanine nucleotide (known as the 7-methylguanosine cap) attached to the mRNA via a unique linkage. This cap structure plays several important roles, including protecting the mRNA from degradation by exonucleases.

Exonucleases are enzymes that degrade RNA molecules by cleaving nucleotides from the ends. By adding the cap structure to the 5' end of mRNA, it provides protection by preventing exonucleases from recognizing and degrading the mRNA from this end. Additionally, the cap structure is involved in other processes such as mRNA export from the nucleus, translation initiation, and recognition by the ribosome during protein synthesis.

In summary, the cap structure protects coding sequences at the 5' end of mRNA from degradation by exonucleases and plays crucial roles in mRNA stability and translation.

A nonsense mutation is one mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.

Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene.

The CFTR gene codes for the CFTR protein whose function is as an anion   channel (chloride ion) which helps control the movement of water in and out of the membrane of cells that are specialized to produce mucus, sweat, saliva, tears and digestive enzymes

When CFTR protein is defective  or absent, thick, sticky mucus accumulates in these cells, obstructing the airways and glands.

The most common mutation of the CFTR gene is a deletion whereby the codon for the amino avid phenylalanine is deleted resulting in the production of a defective CFTR protein.

Another form of mutation in the CFTR gene is a nonsense mutation in which a stop codon is inserted in the middle of the gene resulting in the production of a shortened CFTR protein, which is then degraded by the cell.

Therefore, a nonsense mutation in the CFTR gene leads to cystic fibrosis by causing translation to end earlier in the gene sequence.

Explanation:

Cell replication is an essential process for all living organisms. It is necessary for the production of new cells that are needed for growth and development, as well as for the repair or replacement of damaged or worn out cells.

DNA replication is the process of faithfully copying the genetic information contained in a cell’s DNA so that it can be passed on to the daughter cell when the cell divides.

DNA replication is critical for the continuation of life on Earth because it ensures the faithful transmission of genetic information from one generation to the next.

Without DNA replication, genetic information would become garbled and the species would eventually die out. DNA replication also helps to maintain genetic stability and prevents genetic mutations that could lead to diseases and other problems.

For DNA replication to occur, the DNA strands must be unwound and then copied.

During this process, the two strands of the DNA molecule separate, and then each strand acts as a template for the creation of a new complementary strand.

This produces two identical copies of the original DNA molecule, which are then passed on to the daughter cells when the cell divides.

Because DNA replication ensures the accurate transmission of genetic information, it is essential for the production of new cells, the maintenance of genetic stability, and the continuity of life on Earth.

Dietary fibers from foods such as oatmeal, brown rice, and popcorn are beneficial because they slow down the digestion of carbohydrates. So, option E is accurate.

Fiber-rich foods contain complex carbohydrates that are not easily broken down by digestive enzymes. As a result, these fibers slow down the digestion process, leading to a gradual release of glucose into the bloodstream. This slower digestion helps regulate blood glucose levels and prevents rapid spikes in blood sugar. Additionally, dietary fibers add bulk to the stool, promoting regular bowel movements and aiding in digestive health. However, it's important to note that fibers do not directly digest cellulose, but they contribute to overall digestive health and the elimination of waste.
