A, as with all organisms, growth is always the primary result of cell division, the mitosis type, meiosis cell division results in gametes (sperm and eggs)
Microtubule – serves as a framework of the cell –cytoskeleton.<span>

Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>
Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.

Answer:
(D) Enzymes can function only within living cells.
Explanation:
<em>Enzymes are biological molecules that are proteinous in nature and speed up the rate of biological reactions.</em>
Option A is true because enzymes are not used up or changed when they are used to catalyze reactions
Option B is true. Enzymes are very specific with regards to the reactions they take part in.
Option C is true. Some enzymes contain non-protein component that assist them in their functioning. These non-protein components are called co-factors.
Option E is true. Because enzymes are proteinous in nature, they can be destroyed/denatured by high temperatures.
<em>The only untrue option is D. Some enzymes can function outside living cells. For example, the enzymes involved in digestion can function not just within living cells but also outside it. The functions of some of the digestive enzymes can be demonstrated in the laboratory.</em>
The correct option is D.
i think that the body does its just that the antibodies arent strong enough to combat the virus completely
The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
