Answer:White blood cells, also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system.
Explanation:
Genetic Drift Defined. Populations of organisms are constantly changing and adapting to their environment. Drastic changes in environmental conditions can sometimes cause drastic changes to the gene pool of the population. Genetic drift is when chance events cause changes in frequencies of alleles in a population.
Answer:
There are two basic types of fermentation, both of which produce organic molecules as waste. Ethyl alcohol (C2H5OH) is produced in alcoholic fermentation by fungi, such as brewer's yeast; In the case of lactic fermentation, it is carried out by muscle cells and by bacteria that sour milk, the residue produced is lactic acid (C3H6O3). Knowing that, in both processes, two molecules of each of these substances are produced, it is correct to affirm that: of the reagents such as carbohydrates or glucose that are based on carbonated molecules, produce acids or alcohols as a product.
Explanation:
The fermentation of carbohydrates can then be said to give two possible routes as a product, the alcoholic route that when reacting a carbohydrate with an enzyme or another reagent gives an alcohol, and the acidic route where the carbohydrate reacts with another chemical compound and gives an acid.
Because the group of small cells would have a greater surface area-to-volume ratio, so they are able to exchange materials with their surroundings more efficiently. In shorter terms, they have a greater surface to volume ratio.
A critical part of homeostasis is the tranfer and intake of molecules (whether necessary or not). It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process.
Hope this helped :)
Have a great day
