2. How does the gametophyte obtain nutrition?
bezimeni [28]

Answer:

The gametophyte is generally green and photosynthetic, and obtains water and other nutrients from the soil by direct absorption into its cells. It contains no cells specializing in the transport of water and/or nutrients (vascular tissue) and therefore cannot grow so large as to prevent contact between the soil and the majority of its cells.

Assume that a population is in Hardy-Weinberg equilibrium for a particular gene with two alleles, A and a. The frequency of A is
KatRina [158]

Answer:

q = 0.2, p = 0.8

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

q² = aa = 0.04

q = √0.04 = 0.2

p = 1 - q

= 1 - 0.2

= 0.8

In muscles, ATP is generated by glycolysis from two sources of glucose. One source is glucose that is broken down from glycogen
fgiga [73]

Answer:

The answer is B a net 2 ATPs are always generated per glucose regardless of its source

Explanation

Glycogen breaks down in the muscle so as to have enough glucose for muscle contraction and it produces 2ATPs

Glycogen also breaks down in the liver to release enough glucose which gets to the blood stream and is then taken up by other cells. It also produces 2ATPs at the expense of 6ATPs
