Mitosis produces cells that are genetically identical to the parent cell.
Meiosis includes two distinct processes that contribute to the generation of
genetic variation: crossing over shuffles alleles on the same chromosome
into new combinations, whereas the random distribution of maternal and
paternal chromosomes shuffles alleles on different chromosomes into new
<span>combinations.</span>
The presence of inorganic molecules is the meteorite condition in space similar to what was likely present in Earth's early atmosphere.
The earth initial atmosphere in its early form was too reducing and it was made up entirely of gases such as carbon monoxide, ammonia, methane, nitrogen and other gases.
This atmosphere did not have free oxygen, since it was the result of the mixture of metals, hydrogen and other chemical elements.
The high temperatures, ultraviolet rays and electrical discharges in the early atmosphere would have caused chemical reactions of the elements to form primitive organic molecules.
Meteorites are fragments of solid matter that contain a record of the chemical substances that existed in the early Solar System.
The most predominant gases still found in the space are hydrogen and helium.
Therefore, we can conclude that hydrogen and the presence of inorganic molecules are the initial elements that make up the Earth's early atmosphere and that they are conditions that are present in the space and so in the formation of meteorites.

Answer: I think its B
Explanation: I hope this helps :)
Answer:
True
Explanation:
Two strands of DNA are antiparallel to each other because they appear in opposite direction and are mirror image and they are read in 5' - 3' direction which also refers to the orientation of nucleotides of a single strand of DNA and the reading would start from the free phosphate and it will end at the hydroxyl group
Answer:
b. neurotransmitters
Explanation:
Neurotransmitters are chemical substances released by axons that are the terminal parts of neurons, neurotransmitters are stored in membrane-bound synoptic vesicles at axon terminals. The neurotransmitter discharge happens when a nerve impulse reaches the end of the axons
