They surround and engulf foreign objects and organisms- process called phagocytosis
Zolol [24]3 years ago
5 0

Answer: Option C

Explanation:

The process of phagocytosis can be defined as engulfing the foreign particles and harmful organism so that they cannot harm the body.

When the body gets exposed to different types of foreign materials then there are chances that the body can come across different types of pathogens.

In this case the body response and the phagocytes engulf all the pathogens and organism so that the body is free from infections.

I need help on this question in biology and biology is hard and confusing
Yuliya22 [10]

Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.

Define virus and virion, and describe the parts of a virion.
leva [86]

Answer:

A virus is a tiny infectious biological agent that can only replicate or duplicate inside the host cell. These infectious agents can infect all different types of living organisms ranging from animals and plants to microorganisms and archaea and bacteria.

Virions are ineffective particle or form of the virus outside of the host cell, with RNA or DNA and a protein capsid.

The main role of these infectious agent virions is to transfer the DNA or RNA genome from itself to the cell of host and expressed the gene which means produce proteins from the genome transferred to the host cell.

Diastole is the ________ phase of the cardiac cycle.
STatiana [176]
Diastole is the relaxation phase of the cardiac cycle. It is the normal rhythmic dilation of the heart's valves. During this time, the valves start to gather blood inside of their chambers. There are two types of diastole that occur in the heart, and they are:

1. Ventricular diastole - this is the period where the ventricles are filling and relaxing. 
2. Atrial diastole - the period in which the atria are relaxing. 

This is a continuous cycle that occurs in the heart the moment a person is conceived until the person meets his/her death.
