Can anyone help with this question please

Answer:

A blastocyst is made up of an inner group of cells with an outer shell. The inner group of cells will become the embryo. The embryo is what will develop into your baby. The outer group of cells will become structures, called membranes, which nourish and protect the embryo

Answer:

Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.

Answer:

Glucose

Explanation:

Glucose is the sugar found in plant leaves and is produced by photosynthesis. Photosynthesis requires carbon dioxide. Fructose is found in fruit while lactose is found in milk. Therefore, glucose is the only possible answer. Hope it helps :)

Answer:

Acetone

Explanation:

Answer: Acetone.

Explanation: Acetone molecules have a polar carbonyl group that allows them to ACCEPT hydrogen bonds from OTHER compounds. The slightly positive charge on each hydrogen can attract slightly negative oxygen atoms on other water molecules, forming hydrogen bonds. If acetone is added to water, acetone would completely dissolve.

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.

Answer:

False, it says that all alleles are dominant :D

Explanation:

Answer:

Air lower in the atmosphere is more dense than air above, so air pressure down low is greater than air pressure higher up. ... Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink.

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%

Answer:

antimicrobial resistance

Explanation:

when we use antibiotics some bacteria die but resistant bacteria can survive and even multiply. The overuse of antibiotics make resistant bacteria become more common. The more we use antibiotics the more chances resistant bacteria have to become resistant to them

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.

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.

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 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.
