Answer:
a. 21% G
b. 29% T
c. 29% A
Explanation:
Based on Chargaff's rule, we know that A = T and C = G.
.21 C => .21 G
.21 + .21 = .42
So we know all the C and G is .42. So what's left must be the A and T.
1 - .42 = .58
There's .58 A and T, so divide that in half, because they're equal amounts.
.58/2 = .29
.29 A => .29 T
I only know what question 5 is which is D. Sorry:(
Answer:
Explanation:
While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.The key difference between sexual and asexual reproduction is that sexual reproduction involves two parents of the opposite sex while asexual reproduction involves a single parent.
The ability to reproduce and produce a new generation of the same species is one of the fundamental characteristics of a living organism. It involves the transmission of the genetic material from the parental generation to the offspring generation, ensuring the characteristics of the species and perpetuating the characteristics of parental organisms. Before a new individual reaches its own reproductive stage, it normally has to go through a period of growth and development. Some members of the species will die before they reach reproductive age due to predation, disease and accidental death. So the remaining species will only able to produce more offspring and contribute to the continuation of the species. There are two basic types of reproduction; namely, asexual and sexual reproduction.
