The answer is photosynthesis.
<span>Photosynthesis
occurs in the leaves of green plants. During photosynthesis, carbon
dioxide and water are converted into using the energy of
sunlight to glucose and oxygen. After great evolution of plants, the photosynthetic rate was increased. More plants mean more oxygen produced in the process of photosynthesis. Thus, photosynthesis </span><span> is most responsible for the increase in early Earth’s atmospheric oxygen levels.</span>
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
Virus are living because they:
Reproduce, have Genetic Material (Nucleic Acids) and Adapt
.
Explanation:
Virus have genes or genetic material which are layered in a capsid or protein coat and sometimes a lipid bilayer.
It is not made up of cells yet can be considered a living organism because of the genetic material RNA or DNA in it.
The infect the host and take over host replication machinery and replicates itself. Although it is not able to replicate outside the living body.
They adapt to the host's body environment as many adaptation are present in it as capsid layer which protects its genetic material from getting degrade till the time it reaches nucleus of the cell.
There are 7 point criteria for an organism to be living, virus fulfils some of it except having made up of cells and having cellular organization.

Explanation:
Answer:
B
Explanation:
Crossing over is the process involved during meiosis of two chromosomes sharing genetic information with each other from each parent. This happens so the two daughter cells or sister chromatids have a variety of genetic information and so they are not completely identical. This leads to genetic diversity or variation.
