Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
DNA is, DNA is in prokaryotic cells, which is present in a single circular chromosome, that is located in the cytoplasm. Its in chromosomes, which is in cytoplasm, so technically, DNA is in cytoplasm.
Answer:
The Nervous System.
Explanation:
The nervous system's job is to help in receiving information about the environment around us and generate responses to that information (a.k.a homeostasis). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Hope this helps!
Answer:
Each organism lives in different environments to enable it to survive. All animals from different species have different traits that helps them survive in their environment. And because some animals have many variations of traits in their gene pool it can help them adapt to the changes in their environment.
