The diploid cells have 74 chromosomes, or 37 homologous pairs.
Haploid cells only have one copy of each chromosome. So we can find the number of chromosomes in a haploid cell by dividing the number of chromosomes in the diploid cell by 2.
76/2 = 37
So the haploid cell contains 37 chromosomes.
Answer:
(a) <u>16</u> % of the alien genome is comprised of G.
(b) 17% of the alien genome is comprised of T.
(c) 17% of the alien genome is comprised of A.
(d) <u>22</u> % of the alien genome is comprised of X.
Explanation:
Assuming the alien follows Chargaff's rules which states that DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases.
So if:
16% contains C ; 16 % pairs with G = 32% C-G pairing.
22% contains Y ; 22 % pairs with X = 44% X-Y pairing.
44% G-C + 32% X-Y = 76%
100%-76% = 34% the remaining should be split between T and A which is 17% each one.
Infectious disease is a sickness that can be passed one to someone else, like the flu. a lifestyle disease are sicknesses that you can not get or give to other people.
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
