jeyben [28]

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.

a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere

b) all organisms are descended from one or a few common ancestors

c) the genetic code readily evolves by natural selection

d) there's only one possible way to encode information in a macromolecule

Answer:

b) all organisms are descended from one or a few common ancestors

Explanation:

Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.

A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight g
madam [21]

Answer:

The correct answer is - 11.25

Explanation:

Given:

Average weight gain between weeks 2 and 4 = 10 grams

The narrow-sense heritability of the weight gain between 2 and 4 weeks

= 25%

Then

Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-

by the formula:

Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )

= 10 + 0.25 (15-10)

 = 10 + 0.25 (5)

= 10 + 1.25

  = 11.25

Thus, the correct answer is - 11.25

Describe the basic components of<br> DNA (deoxyribonucleic acid).
Reika [66]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
