QUESTION 1
wel

The individual bacteria would appear larger under the magnification of 40X. Thus, the correct option is A.

<h3>What is Magnification?</h3>

Magnification may be defined as the power of a microscope to deliver an image of an entity at a scale larger and sometimes smaller than its genuine size.

Bacillus subtilis is a distinct germ, that is rod-shaped in structure and is Gram-positive. Under the 40X microscope, it looks as rough, opaque, fuzzy white, or narrowly yellow with irregular edges.

The size of the entity or any object under the microscope of 40X magnification is 5mm, while the of the entity or any object under the microscope of 10X magnification is 1-2mm.

Therefore, it is well described above.

Why does a virus lethal to us not infect animals? I know that RNA viruses mutate at 10,000 to a million times faster than DNA vi
Setler [38]

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 is the process where organisms that are better suited to their environment reproduce and pass on their genes more successfu
maxonik [38]

Answer:

Natural selection

Explanation:

Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.

This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
