Answer:

Two factors determine whether a molecule will cross a membrane:

1. the permeability of the molecule in a lipid bilayer and

2. the availability of an energy source.

The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of lipid and is highly soluble in the nonpolar environment of the lipid bilayer.

Can someone please do a summary on how wind works? 7-9 sentences please I will mark brainliest!
Mars2501 [29]

Answer:

Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.

By using sound waves, _______ signals allow oceanographers to determine ocean depth. A. radar B. phone C. sonar D. radio
ryzh [129]
<span>The appropriate answer is c. sonar. Oceanographers use sonar to determine the ocean depth. A sonar signal is sent from the ship. Oceanographers record the time taken for the signal to leave the ship and for it to return. Knowing the speed of sound in water, they are able to calculate the depth of the water. This method is also used to generate bathymetric images of the ocean floor. </span>

Explain why you can see the Moon.<br><br><br> Science
Ghella [55]

Answer:We see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth. As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
