The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.

<h3>Why does a virus lethal to us not infect animals?</h3>

For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

What could be a result of an injury to the dorsal column? loss of sensation to pressure and touch loss of control over all invol
IRINA_888 [86]

Answer:

The correct answer would be a loss of sensation to pressure and touch.

The dorsal column-medial lemniscus pathway abbreviated as DCML refers to the sensory pathway of the central nervous system (CNS) which transmits sensations of vibration, fine touch, proprioception, and two-point discrimination from the skin as well as joints.  

Thus, injury to the dorsal column would result in the loss of sensation to touch and pressure.

Which best compares the respiratory system to the circulatory system?
andrew11 [14]

Respiratory system is refers to as the organs which are involved in breathing such as nose, throat, larynx, trachea, bronchi, and lungs. It is also known as respiratory tract.

The  circulatory system  is refer to as which contains the heart and the blood vessels and blood moves throughout the body in vessels. This circulatory system helps tissues to get enough oxygen and nutrients, and it helps them get rid of waste products.

<h3></h3><h3>What is breathing?</h3>

When person inhale (breathe in), air enters in the lungs, and oxygen from atmosphere moves to body blood. At the same time, carbon dioxide, a waste gas, moves from blood to the lungs and is exhaled (breathed out).

Breathing process is known as gas exchange which is is essential to life.

A student analyzed a viral genome and found that the genome had the following nucleotide composition. 28% adenine 20% thymine 35
egoroff_w [7]

Answer: Option A) Double-stranded DNA

Explanation:

First, the presence of thymine infers that the genome is DNA.

Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%

A + C + G + T = 100%

28% + 35% + 20% + 17% = 100%

Since all bases makes 100%, we can conclude that the genome is a double stranded DNA
