The answer is A, it's made out of buried plants and animals
Answer:
Companion cells
Explanation:
Companion cells are important structures found in the vascular bundle known as the phloem of plants. They work together with sieve cells in the movement of vital compounds such as Protein, ATP etc to other parts of the plant.
Companion cells are also known as living cells that do not conduct sugar themselves but they play a very important role in the movement of these substances.
23 but when a sperm cell meets the egg the egg gets 23 genes from the mom and 23 from the dad then the baby will have 46 chromosomes all together

Answer:
e. is mostly asexual, with sexual as a second option.
Explanation:
Protist are unicelluar eukaryotic microorganims. Example include:
<u><em>Amoeba</em></u> <u><em>proteus</em></u>
<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>
Dinoflagellates, etc.
Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.
Protist reproduce asexual by binary fission or by budding.
Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.
Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.
They also reproduce sexually by conjugation.
Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.
