Answers
Answer: Testosterone, follicle stimulating hormone
Explanation:
Testosterone is a sex hormone produce by the male sex organs or testes typically in the seminiferous tubules. It incudes male sexual characteristics that is the production and development of sperms in males. The follicle stimulating hormone is involved in causing the maturation of the eggs or female gametes in the female sex organs or ovaries. It also induces the mensuration cycle in females. FSH also have a role in stimulating the spermatogenesis in males as it acts on the Sertoli cells of the testes and stimulates the sperm production.

NO LINKS The arctic is an environment in which the temperature is often below freezing. The polar bear and the walrus are both animals which are native to the arctic region. What structures do both of these animals share that allow it to survive in this environment? Explain your thinking.
Answers
Answer:
Polar bears are found in very cold parts of the world where temperatures can drop as low as -20° Fahrenheit (-29° Celsius). Without proper protection, this weather can be deadly, so polar bears stay warm by utilizing their thick fur and fat, or blubber. Polar bears have evolved along with other Arctic animals to take advantage of minimal warmth, and can sometimes actually become too warm because their bodies are so efficient at trapping heat.
As for walrus', they cannot put on a coat to stay warm, but they can use layers -- layers of blubber! A walrus's hide is about one inch thick. Tucked underneath this tough skin is a layer of blubber. This layer of fat is from three to six inches thick. Just like our layers of clothes, a walrus's layer of blubber helps it stay warm.

Answers
Answer:
Animals in space originally served to test the survivability of spaceflight, before human spaceflights were attempted. Later, other animals were flown to investigate various biological processes and the effects microgravity and space flight might have on them. Bioastronautics is an area of bioengineering research which spans the study and support of life in space.
Explanation:
Example 1: Albert II became the first monkey in space on June 4, 1949. He reached an altitude of 83 miles (134 km), but died on impact when the parachute failed. A previous monkey, Albert I, died when the V-2 rocket failed before reaching peak altitude. Two other monkeys, Albert III and IV, also died when their rockets failed.
Example 2:A mouse launched on Aug. 15, 1950, attained an altitude of 85 miles (137 km), but died when the rocket disintegrated due to parachute failure. Several other mice were launched during the 1950s.
Example 3 (and the most important example): Laika became the first living being to orbit the Earth on Sputnik 2, Nov. 3, 1957. She died several hours into the flight from stress and heat.

Rock pocket mice are rodents found in the desert Southwest. They are typically light/tan, but a mutation in the population codes for a
darker fur color. The two fur colors are shown in the images here. The area where these mice live typically have a sand with a tan
background. However, there are areas of cooled lava from a volcanic eruption 10,000 years ago that deposited black rock. The mice
are found on the sand and on the rocks.
Researchers set traps to collect samples of mice from the rocks and the sand areas. An analysis of the data for the mice caught in
each of the areas would show which trend if natural selection were acting on the different phenotypes?
Answers
Answer:
B) Visual predators favored the tan mice on the dark rock and black mice on the light rock.
C) The black mice on the black rock camouflage better, allowing them to survive and reproduce.
E) There are more black mice in the dark environment and more tan mice in the light environment.
Explanation:
I just did it on USATestPrep
The correct option are :
The visual predator favored the tan mice on the dark rock. The black mice on the black rock can camouflage better. The more black mice under dark environments and more tan mice under light environments.What are rock pocket mice?The rock pocket mice are 19 specie of the pocket mice and they are found mainly in the rock out crops of the desert of the southwestern US and Mexico and medium-sized mice of 18 cms.
They have a breeding season that starts in fed to march. They are dark in color and can easily camouflage with the surroundings and this gives them an advantage over the light white mice.

What are the answers to 10 and 11?
Answers
Answer:
The correct answer is -
10. 20 J
11. 29.31 %
Explanation:
According to the law of 10% energy transfer, the energy only transfers 10% energy from one tropic level to another and the rest 90% lost in the form of heat during the metabolic and excretion process.
So, 2000 J transfers only ten percent to the primary consumer that is 200 J and then ten percent of that transfers to long-tailed weasels that are 20 J.
11. The percentage efficiency -= energy after transfer*100/transfer before the transfer
= 350*100/1170 = 29.31%
