Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
There are three phases of stem cells mitosis, gene expression, and differentiation.
<h3 /><h3>What are stem cells?</h3>
Stem cells that are totipotent or omnipotent. programmable stem cells. Multiple-potency stem cells, stem cells with oligopotency, the body's building blocks are stem cells, which are cells that give rise to all other cells with specific roles.
Daughter cells are created when stem cells divide properly in the body or a lab to create additional cells. Most stem cells are found in the bone marrow.
They divide at this stage to produce new blood cells, Once fully developed, blood cells leave the bone marrow and travel into circulation.
Therefore stem cells develop into different cells through differentiation.

I personally think that video games are not a problem in a normal ‘teenagers’ life but if their parents or guardians are not being responsible it can cause some
Problems however for someone adults who put video games before a job or a relationship that’s 100% a problem so in conclusion you need to be responsible doesn’t matter if your a kid or a adult don’t let video games control your life or your health
Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)
In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
