This condition was caused by the human immunodeficiency virus (HIV). This virus can reduce the number of white blood cells.

<h3>What is HIV?</h3>

The human immunodeficiency virus (HIV) is an infectious virus that attacks the immune system.

White blood cells or lymphocytes can be considered fundamental players of our immune system that attack pathogenic viruses.

The human immunodeficiency virus (HIV) can infect and then eliminate CD4+ white blood cells.

Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?
Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

  • Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
  • Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

  • Solar energy
  • Nuclear energy
  • Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .

leonid [27]
<span>At the end of meiosis II, compared to the DNA from the original cell, the DNA in each of the four new cells is C)half as much and genetically different from the original. Meiosis is the type of cell division in which the genetic material is reduced by half. Thus, choices B and D are incorrect. Further, the exchange of genetic material between homologous chromosomes so-called the crossover occurs during meiosis, so DNA in new cells will be genetically different from the original DNA. Thus, the correct choice is C.</span>
