<u>Answer:</u> A. Tissues
<em>Cells that perform similar functions combine to form tissues.
</em>
<u>Explanation:</u>
Cells are the smallest units in the body of an organism. Based on number of cells in an organism’s body they can be classified as unicellular or <em>multicellular organisms</em>.
It is the group of cells performing similar functions that form a tissue. Group of tissues performing similar function forms an organ. <em>Tissue structure and function may differ in plants and animals. </em>

</em>
It will increase the amount of ground level ozone in many regions, and result in impacts of air quality.
This will cause problems for ozone standards in the future.

D, since it is semi-permeable then it will be able to control what enters and leaves.The cell membrane is a bi-layer its outer surface is hydrophilic and inner surface is hydrophbic so the substances that pass through it have to be sufficiently hydrophobic and hydrophilic in order to pass it and it also has small openings in it which allows the free exchange
I believe it’s “B” as typically thermophiles thrive in high temperatures, between 45-80°c
