Answer:

Option (2).

Explanation:

Zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. The zygote undergoes further development inside the female womb.

The embryonic period starts from the third week after the conception. The important organs and structure development occur during the embryonic period. The formation of three germ layers occur in this period.

Thus, the correct answer is option (2)

A guinea pig with giant muscles is bred with a guinea pig with regular muscles. If muscle size in guinea pigs is INCOMPLETE domi
Whitepunk [10]

Answer:

Yes, they would be able to produce weak muscled guinea pigs

Please see details below

Explanation:

This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.

According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:

GG - G and G

RR - R and R

Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:

GR, GR, GR, and GR

This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production
natima [27]

Answer:

This question lacks options, the options are:

a) Negative primary production

b) Net primary production

c) Secondary production

d) Negative secondary production

e) Positive primary production

The correct answer is b.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.

Explanation:

Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).
