You didn't give options so I couldn't properly answer your question.
However, hope this helps xox :)
Any pair of chromosomes other than that of sex pair of chromosomes are referred to as autosomes or autosomal chromosomes.
Answer:
C Volcanic activity releasing carbon into the atmosphere.
Explanation:
The statement that best describes the cycling of carbon between the atmosphere and geosphere among the options is volcanic activity that leads to releasing carbon into the atmosphere.
Volcanic activities has to do with the activity of the geological layer of the earth that leads to the emission of gases, eruption of lava or the combination of the two.
When a volcanic activity leads to the release of carbon related gases such as carbon dioxide into the atmosphere, carbon is being circulated between the geosphere (the earth) and the atmosphere (the air).
Hence, the correct option is C.
Answer:mitosis
Explanation:meiosis produces haploid gametes. Mitosis is simple cell division
Answer:
No, Presence of different alleles for an X-linked gene is required to test the Lyon hypothesis.
Explanation:
According to the Lyon hypothesis, to compensate the dosage of X linked genes in males and females of mammals, one X chromosome in all the cells of a female mammal is inactivated and the presence of the gene on the other X chromosome is expressed.
Inactivation of the X chromosome is a random process, that is, either maternal or paternal X chromosome may be inactivated during early embryological development in females.
To test the Lyon hypothesis, the expression of alternative alleles of an X-linked gene in the cells of a female mammal is studied. Given that the human female is homozygous for an X-linked gene, all of her cells would express the same allele for the gene, and the Lyon hypothesis can not be tested.
