Answer:
A. Early signs of life on earth
Explanation:
The Hadean, before the Archean, is the first geologic eon of Earth. It began with the formation of the Earth about 4600 million years ago and ended 4,000 million years ago. The planet had just formed and was still very hot due to high volcanism, a partially molten surface. Some geologists labels the period before the earliest-known rocks on Earth. At the end of it much cooler surface temperature and the formation of solid rock enabled to flaurish the life.

Answer:
The two main reasons are nonpolar core of the bilayer and the active transport.
Explanation:
The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.
If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.
One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
When cells communicate by the signaling process, one cell produces a signaling molecule that must be received by the signal receptor on or in the responding cell. Signaling molecules are often called ligands, a general term for molecules that bind specifically to other molecules (such as receptors).
Answer:
It is known as <u>Progressive Muscle Relaxation</u>
<em>b) She alternates muscle tension and relaxation of various muscles in her body.</em>
Explanation:
PMR is a healthy coping skill normally learned in any kind of psychiatric business. For example, I learned PMR while I was inpatient at a behavioral health unit. The way we did PMR was that we'd sit up in our chairs and start from the toes and on up. We squeezed our toes together for a few seconds and then released and then we'd do it a second time. After the toes, it would move up to the feet and we'd use the same process for that and for the rest of the joints.
