Which describes the temperature for successful sperm production? slightly higher than body temperature slightly lower than body

gladu [14]

Answer:

The correct answer is - slightly lower than the body.

Explanation:

Spermatogenesis is the process of the generation of sperm. It is the process that requires a slightly low temperature than normal body temperature to produce sperms in viable conditions.

This is the prime reason for the location of the scrotum which is outside the body which allows to testes maintain lower body temperature lower than the rest of the body. There is a 1-8 degrees C difference in the rest of the body and testes.

A neuron's ability to generate action potentials depends: Question 1 choices Choice A., on the axon reaching threshold and the o

SOVA2 [1]

Answer is A
Firstly axon must reach the threshold level and then depolarisation occurs. Depolarisation phrase means sodium enters and potassium leaves the axon . Choice C can't be because main idea is the entering of sodium ions.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort

Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide $(CO_2)$ , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

<u>Explanation:</u>

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - $(CO_2)$ combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.

4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the

dalvyx [7]

Given that,

The speed of a wave, v = 200 m/s

Wavelength, $\lambda=2\ m$

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

$v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz$

So, the frequency of this wave is 100 Hz.
