<h2>Answer:</h2>
The correct statement is option A which is, "A gene is a segment on the DNA. DNA is wrapped in proteins to form a chromosome".
<h3>Explanation:</h3>
- A gene is the part of DNA in the nucleus which encodes for the specific trait in the body. DNA is the nucleotide sequence which is the blue print for the whole organism. It contains genes for all the structures and functions in the body.
- So it is very long sequence containing the million of genes. So in nucleus it is present in compress form. It is wrapped on the histones proteins and condense and supersondense into a specific structure which is known as chromosome.
As both fill with liquid they expand. They are also both rounded shapes
The answer is c because many things are losing their habitat and food sources
Answer:
A. an increase in genetic diversity
Explanation:
Genetic diversity is the degree of gene variety within a single species (animal or plant). It corresponds to the total number of genetic characteristics in the genetic composition of species or subspecies. Genetic diversity is one of the main aspects of our planet's biodiversity, such as populations and ecosystems.
In the case of Siamese cats, genetic diversity has caused some lineages to change their appearance from classic to modern. This occurred by crossing Siamese cats with cats of other breeds, creating a wide genetic variety that resulted in the change in appearance of these cats.
