Explanation:
The question that is most likely to be studied by biologists could be "What is the effect of exercise on heart rate in horses?" since they study everything related to the Life. <em>Hope</em><em> </em><em>this</em><em> </em><em>answers</em><em> </em><em>your question</em><em>.</em><em>.</em><em> </em><em>And</em><em> </em><em>good</em><em> </em><em>luck</em><em>!</em><em> </em>
<span>The cell has 1% concentration of the salt. The external environment is highly concentrated with 25% saline solution. This will lead to release of water outside the cell, by passive diffusion from a region of high conentration of solvent to lower concentration. Thus, the cell will shrink.</span>
<h3><u>Answer;</u></h3>
Lithosphere
<h3><u>Explanation</u>;</h3>
- Lithosphere is the solid outer part of the earth which includes the brittle upper portion of the crust and the mantle. It is bounded by the asthenosphere below and the atmosphere above.
- <em><u>The pressure in the lithosphere is about 109 gigapascals or GPa. </u></em>
- <em><u>Asthenosphere has a pressure of about 18 GPa</u></em>
- <em><u>The mantle is a layer between the outer core and the crust, it has a pressure of about 149 GPa.</u></em>
1) The answer is <span>bluegreen algae
</span>
Bluegreen algae or cyanobacteria <span>are thought to have started life on earth because they converted the atmosphere that didn't have a lot of oxygen, into an atosphere with enough oxygen to exist life. That </span>oxygen was a product of their photosynthesis.
2) The answer is lightning.
<span>By Primordial Soup Theory, life began as a result of the combination of chemicals from the atmosphere and lighning (a form of energy) to make amino acids. Aminoacids are necessary to build proteins, and proteins are necessary for all the organisms.</span>
Answer:
Chemicals that are secreted from antigen-presenting cells then activate helper T cells.
