Animal A and Animal B each have 95% of their DNA in common. Animal A and Animal C each have 50% of their DNA in common. What doe
s this suggest about the relationship of these animals? A. B is probably much more closely related to C than to A. B. C is probably much more closely related to B than to A. C. A is probably much more closely related to B than to C.
C. A is probably much more closely related to B than to C.
As per the information given in the question, Animal A and B have 95% of their DNA in common whereas Animal A and C have 50% of their DNA in common. This indicates that DNA sequence of Animals A and B are more similar as compared to the DNA sequence of Animals A and C.
DNA is the genetic material of living organisms that is transferred from one generation to the next. A change in the sequence of DNA takes place when organisms evolve.
Two organisms are said to be related to each other if they share more genetic relatedness ( that is similarity in their DNA sequence).
Fertilizers are inorganic o organic nutrients highly rich in elements like nitrogen, potassium and phosphorus which are essential for the growth of plants.
The application of excess fertilizers in the soil causes the surface run off as well as leaching of these nutrients into the soil from where it is gradually transferred into the nearby water bodies, in this case the lake adjacent to the farmer's property.
In the lake, these nutrients promotes the growth of plants like algae.
The excessive growth of algae in the lake disturbs he ecological balance of the lake and causes a dearth of oxygen in it. This phenomenon is said to be called Eutrophication.
The reduction in the level of oxygen in the lake causes the animals, like fishes, in it to gradually die.
<span>In 80% of the cases of offspring with cri-du-chat syndrome, the father's gametes were the source of the deletion of the chromosome as opposed to the mother's egg being the cause. Therefore, cri-du-chat is largely caused by the father's genetics, not the mothers.</span>
