The answer is a. I'm pretty sure
M. J. Schleiden:
In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)
<h3>
What is cell?</h3>
All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.
His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.
Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.
Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.
His experiment:
Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

There are five basic types of emergencies that every hunter should know about, these types are as follows:
1- victim not breathing or is unconscious: You can make sure that the victim is unconscious by simply shouting at him. If he's unconscious or not breathing, he won't reply. In this case, the hunter has to check that the airway passage is completely clear and there are no obstructions in it. After that, the hunter has to check if the victim started breathing or not. If not, then CPR is required. A last step is for the hunter to check the victim's pulse.
2- victim with burns: first thing is to check the type of burn. If it is first degree burn (burn that is on the surface of the skin), then it can be treated by cold water and aspirin. If the burn is from the second degree (blister is more serious and the burn is deeper under the skin). then it should be treated by covering it with a sterile and dry bandage without applying any pressure. If the burn is third degree (very deep into the skin and is into the flesh) should be covered with a sterile and dry bandage until qualified medical help is provided.
3- victim bleeding: The bleeding must be stopped as soon as possible and must be covered to prevent infection.
4- victim with break or sprain: it is difficult to know the difference between fracture and a break, therefore, the best scenario is to use sticks or splint boards to keep the fracture or the bone from moving.
5- victim in shock: shock can slow down the heart and might lead to death. The best treatment for shock is to make sure that the victim is comfortable, secured and dry.<span />
