Somatic cells or body cells of an organism undergo cellular division that maintains the number of chromosomes of the beginning cell prior to the division, this process is called mitosis.
The answer is vacuole and centriole lysosome. An animal cell contains all 3.
An animal cell does not have chloroplasts and a cell wall(a plant has those things). A plant uses chloroplasts (that contains chlorophyll) for photosynthesis. A cell wall is to give the plant a rigid shape(that's why most plant cells look rectangular while animal cells look circular).
Hope this helps :)
Answer:
Although the process of DNA testing provides promising results in the forensic department, it still has certain limitations. Some of the problems with DNA testing are:
<em>1) It takes a lot of time to process a single piece of DNA. Along with time, this process is also very expensive.</em>
<em>2) Some critics consider DNA as a violation of ethics. This is because not all of the suspects are culprits. And the blood of all of the suspects is taken to determine a single culprit. Some people consider it unethical for taking the blood of the suspects as humanism is against it.</em>
<em>3) Some countries are working on making DNA databanks, where they will be able to simply compare the sample taken from a crime scene with the DNA databank. In this way, they will easily be able to identify the culprit. This process is again considered to be unethical besides the large amount of money that will be used to create such a large databank. </em>

Answer:
A. fossils of archaic humans show we have evolved through the differences in bone structure. Humans used to look a lot like chimps, and through fossils we can see differences in our skull shape and size, differences in the amount of body hair we had, and through vestigial bones like wisdom teeth, which we do not need anymore today. Wisdom teeth were likely used to chew raw meat, which we do not do anymore.
C. Chimpanzees are our closest living relatives on the planet, with 99% of our DNA being the same.

Sorry the first one is lengthy, I don't know how long it should be but I hope that helped
Answer:
The result is a Positive Oxidase test
Explanation:
The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain. (note: All bacteria that are oxidase positive are aerobic, and can use oxygen as a terminal electron acceptor in respiration. This does NOT mean that they are strict aerobes.
The reagent is a dark-blue to maroon color when oxidized, and colorless when reduced. Oxidase-positive bacteria possess cytochrome oxidase or indophenol oxidase (an iron-containing hemoprotein). These both catalyze the transport of electrons from donor compounds (NADH) to electron acceptors (usually oxygen).
