Answer: The correct answer is-

a tube that stores and develops sperm cells from the testes.

Epididymis is tube like coiled structure that receives sperms from testes, stores them and partially matures them ( as sperms gain mobility in this region through mobility of its flagella).

It has three parts namely, head (largest part, lying at the top of testes and receives sperms) , body ( a highly coiled/ twisted region), and tail region ( that transports sperm to vas deferens) .

Answer:

$\boxed{\sf A. \ 51 \ mL}$

Explanation:

Amount of water displaced by the sphere will be equal to the volume of complete sphere.

As the sphere completely sinks to the bottom of the cup.

We have been given;

Diameter of sphere (d) = 4.6 cm

So,

$\sf Radius \: of \: sphere \: (r) = \frac{Diameter \: of \: sphere \: (d)}{2} \\ \sf = \frac{4.6}{2} \\ \sf = 2.3 \: cm$

Volume of sphere (V):

$\boxed{ \bold{V = \frac{4}{3} \pi {r}^{3} }}$

By substituting value of r we get:

$\sf \implies V = \frac{4}{3} \times \pi \times {(2.3)}^{3} \\ \\ \sf \implies V = \frac{4}{3} \times 3.14 \times 12.167 \\ \\ \sf \implies V = \frac{152.81752}{3} \\ \\ \sf \implies V = 50.94 \: {cm}^{3} \\ \\ \sf \implies V \approx 51 \: {cm}^{ 3}$

1 cm³ = 1 mL

$\therefore$

V = 51 mL

So,

Water displaced by the sphere = 51 mL

In which group is parthenogenesis a normal event?

bezimeni [28]

Answer:

Bees

Explanation:

Parthenogenesis is a method of asexual reproduction in which an egg cell develops into a new individual without fertilization. Parthenogenesis occurs in insects, amphibians, reptiles, fish, and in some plants. Most of the organisms which reproduces through parthenogenesis, they also reproduce sexually. Parthenogenesis may be occurs by apomixis and by automixis. In apomixis, egg is produced by mitosis and results into diploid clones. In automixis egg is produced by meiosis and the haploid egg develops into diploid new individual by the duplication of chromosomes. Parthenogenesis is an adaptation which allows to reproduce in adverse environmental conditions when sexual reproduction is not possible.
