Answer:
Explanation:
According to Erwin Chargff's rule, he stated that, adenine (a purine) always forms base pairs with thymine (a pyrimidine) and that guanine (a purine) always forms base pairs with cytosine (a pyrimidine). an adenine does not form base pairs with cytosine despite it being a pyrimidine.
thus the amount of adenine will always be equal to that of thymine while
the amount of guanine will always be equal to that of cytosine. Therefore, since we have 22% of adenine, the amount of thymine will also be 22% making a total of 44%. thus to find the amount of guanine and cytosine = 100-44= 56%.
the amount of guanine will thus be 56/2= 28%, since guanine and cytosine are of equal amount.
Answer:
In primary succession there is no presence of soil or the soil cannot support life in secondary succession there is a presence of soil in which it can support life
Explanation:
Biological dispersal is the act of movement of individuals from their birth site to a breeding site or from one breeding site to another. It is a phenomenon that contributes to gene flow and affects population genetics and species distribution. Also, it strongly affects population dynamics and induces changes on the ecosystem.

A virus<span> is a small </span>infectious agent<span> that </span>replicates<span> only inside the living </span>cells<span> of other </span>organisms<span>. Viruses can infect all types of </span>life forms<span>, from </span>animals<span> and </span>plants<span> to </span>microorganisms<span>, including </span>bacteria<span> and </span><span>archaea
</span>While not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles. These viral particles<span>, also known as </span>virions<span>, consist of two or three parts: (i) the </span>genetic material<span> made from either </span>DNA<span> or </span>RNA<span>, long </span>molecules<span> that carry genetic information; (ii) a </span>protein<span> coat, called the </span>capsid<span>, which surrounds and protects the genetic material; and in some cases (iii) an </span>envelope<span> of </span>lipids<span> that surrounds the protein coat when they are outside a cell. The shapes of these virus particles range from simple </span>helical<span> and </span>icosahedral<span> forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an </span>optical microscope<span>. The average virion is about one one-hundredth the size of the average </span>bacterium<span>.</span>
