Which of the following changes takes place during the third trimester of a womans pregnancy
A.) the fetus begins to form teeth
B.) the fetus develops toenails,lips, and eyelashes
C.)The mothers uterine contractions begin
D.) the fetus’s hands and feet appear
Answer:D
Explanation:
The fetus develops toenails, lips, and eyelashes is the change that takes place during the third trimester of a woman's pregnancy. Therefore, option (B) is correct.
What happens in third trimester?By the third trimester, which begins around the 28th week of pregnancy and lasts until birth, the fetus has already formed most of its organs and body parts. During this stage of pregnancy, the fetus undergoes significant growth and development. This includes the development of toenails, lips, and eyelashes. Additionally, the fetus begins to accumulate body fat, and its brain undergoes rapid development.
To answer the other options, the formation of teeth begins during the embryonic stage, which occurs in the first trimester. The mother's uterine contractions typically do not begin until labor, which occurs at the end of the third trimester or later. The fetus's hands and feet appear during the embryonic stage, specifically around the 6th week of pregnancy.

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?
Answer:
to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
Explanation:
Firstly, let us calculate the number of calories burnt in 2 hours
in 10 minutes; 30 calories are burnt
∴ in 1 minute 30/10 calories are burnt = 3 calories are burnt
2 hours = 120 minute
∴ in 120 minutes 3 × 120 = 360 calories are burnt.
Next, let us calculate the amount of trail mix that contains 360 calories
100g of trail mix = 450 calories
450 calories = 100 g
1 calory = 100/450
∴ 360 calories = 360 × (100/450)
= 360 × 0.222 = 80g
∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

How does the tRNA-mRNA interaction ensure that the amino acids are added in the correct order?
Answer:
Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA.
This system ensures that amino acids are added to the chain in the correct order. At the beginning of translation, the ribosome and a tRNA attach to the mRNA.

The diagram below represents the circulation of air above Earth's surface at a coastal location during the day and at night.
This local air movement is best described as an example of
1.
conduction between Earth's surface and the atmosphere above it
2.
condensation of water vapor during the day, and evaporation of water during the night
3.
convection resulting from temperature and pressure differences above land and water
4.
greater radiation from the warmer ocean during the day and from the warmer land at night
Submit Answer
Answer:
3. convection resulting from temperature and pressure differences above land and water
Explanation:
Due to the the difference between the ability of land and to water to absorb and radiate heat energy, the land gets heated up by the sun more quickly than water during the hot afternoons. As a result, the air above the land surface gets heated up more quickly than that above water. Warm air being less dense than cold air will rise above to atmosphere creating a low pressure area on land. On the other hand, air above water is not heated up as quickly, thus the dense cooler air over water will rush in and replace the warm air that has risen above the land surface.
At night, the land cools off more easily than water, hence the air above the land surface is cooler. On the other, water does not lose heat as quickly as the land, hence the air above the water surface is warmer than that over land. Warm air over the water surface will rise above, while colder air from land will replace it.
How have freshwater and salt water fish adapted to deal with osmosis in their respective environments?
Answer:
Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis

The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?
Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.
Answer:
earthquakes occur when the edges suddenly become unstuck and slip along a fault
