Nitrogen is so important to plants because it is a major component of chlorophyll , or the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (photosynthesis). It is also a major component of amino acids, the building blocks of proteins for plants.
Because we can't take in light energy directly, we consume plants. Plants convert light energy into chemical energy through the process of photosynthesis. So when we eat plants, we get the chemical energy stored in the carbohydrates, which fuels all our physical activity.
The picture is not popping up maybe post it again.
Answer: D) retroviruses
Explanation:
Retroviruses are a type of virus that converts its genetic material into DNA using a special enzyme, called reverse transcriptase. The DNA is then able to integrate into the DNA of the host cell. Once integrated, the virus can make additional viral particles using the components of the host cell.
Retroviruses which cause cancer at low incidence do not contain host information inserted. Rather, they tend to cause cancer via the expression mutation of potentially oncogenic host genes. Retroviruses incorporate proviral DNA into their host's chromosomal DNA during their natural life-cycle. Provirus DNA promoter affect regulatory gene expression over.
Hence, the correct option is D.
Answer:
Photosynthesis and Oxidative Phosphorylation
Explanation:
The mitochondria uses oxygen within the cell to convert the chemical energy we get from the foods we eat, this makes energy in a usable form.
Chloroplasts help plant cells undergo the process of photosynthesis
