The diagram below shows the position of the sun, moon, and Earth. The labels A, B, C, and D represent four coastlines on Earth.Three circles are shown. The smallest circle is in the middle and is labeled Moon The circle labeled Earth is on the left of the moon and the biggest circle is labeled Sun and it is on the right of the moon. The circle labeled Earth has A marked on top, B marked on the right, C marked below, and D marked on the leftAs Earth rotates, coastline B moves to where coastline A is. Which statement is correct about coastline B in its new position?It will experience a high tide because water is drawn away from the area between the low tides.It will experience a low tide because water is drawn away from the area between the high tides.It will have a low tide because the greatest gravitational pull of the moon is experienced when the coastline is at right angles to the moon.It will have a high tide because the greatest gravitational pull of the moon is experienced when the coastline is aligned with the sun and moon.

How does the immune system work together with the circulatory system to function properly? A.The immune system's red blood cells fight and destroy foreign antigens.B.White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.C.The circulatory system's arteries cause the immune system to work harder by bringing oxygen-depleted blood to the infection site.D.Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.

Pls help :(Which lettered points would you use to show Zoe's voluntary action of choosing to move her leg out of the way? What
should the labels be?

Answers

Zoe'svoluntary action of choosing to move her leg out of the way is labeled as point D. Point B is the one from which signal travels down spinal cord to skeletalmuscle. Zoe uses muscle to move leg out of the way from point C.

What are voluntary action?

Voluntaryaction occurs when an action is performed with the involvement of thoughts.

Voluntary actions are usually being controlled by brain. These are the actions that are takes consciously which is done by coordination of brain and spinal cord.

In the given scenario, Point D represents Zoe's voluntary action of moving her leg out of the way. Point B is where the signal travels down the spinal cord to the skeletal muscle. Zoe uses muscle to move her leg away from point C.

Thus, the answer is pointD.

#SPJ5

Answer:

Because this action is a voluntary action, it starts in the brain. Here are the steps:

D: Zoe chooses to move her leg into a different position.

B: Signal travels down spinal cord to skeletal muscle.

C: Zoe uses muscle to move leg out of the way.

Point A is not used in this sequence of steps.

Favorable traits are traits that promote an organism's success in a particular environment. Organisms with favorable traits are more likely to thrive, survive, and reproduce than organisms without favorable traits. Over time, favorable traits are likely to________ within a population and unfavorable traits are likely to ________ within a population.

Answers

Answer: Grow ; Disappear.

Explanation:

The organism that best suits in the environment is likely to grow and reproduce and its population in the environment increases.

Over the time the characters that are favored more survive and the characters that does not allows the organism to survive in harsh conditions are not favored.

These organism die and over the time the traits disappear from the population.
1. Evolve/Grow
2. Disappear

It's because they can survive and reproduce while the unfavorable die off and cannot reproduce, so their traits disappear from the gene pool.

Which of earth layers has the same chemical composition as the mesosphere

Answers

Answer:

astenosphere

Explanation:

The mesosphere and the astenosphere are both part of the mantle. The mesosphere is the deeper part, while the astenosphere is the outer part of the mantle. Both of these layers have the same chemical composition, but the temperature and pressure are different in them. The mesosphere has higher temperature and pressure, so even though it is very hot, the rock is actually solid. The astenosphere has lower temperature and pressure, so the rock is more liquid.

Answer:

astenosphere
