m_a_m_a [10]

Answer:

Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.

S phase

Explanation:

 DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.

Carbon dioxide

SOURCE:- carbon dioxide can be from both human and natural source. Example of the sources includes; natural source ( ocean release, decomposition and respiration), human activities ( burning of coal, oil and natural gas, cement production etc)

IMPACT:- carbon dioxide causes difficulties in breathing as it displaces oxygen in the air.

IMPACT:- Nitrogen oxides has also been linked to many respiratory health issues such as bronchitis and wheezing. It causes the lining of the lungs to inflame there by reduce the immunity of the lungs to respiratory diseases.

Methane

SOURCE:- methane can be from either natural or human activities. The natural source includes; food digestion by cattles, decay of organic materials. Human activities such as waste management, rice production, oil and gas production etc.

IMPACT:- Methane is considered a green house gas like carbon dioxide, it contributes to the trapping of heat energy in the atmosphere which causes global warming. It is also linked to serious health issues such cardiovascular, respiratory and neurological problems.

Particulates

SOURCE:- particulates are fine tiny particles of matter found in the air, it might be in solid or liquid form. Example; dust, smoke, fumes etc. This particles can suspended in the air for an extended periods of time.
