C) the phases are there for the cell to grow and mature properly ( much like a human) - if they don’t grow properly they won’t be able to reproduce.
1) control - does not get independent variable 2) experimental - gets the independent variable 3) independent variable - is being changed/controlled 4) dependent - is being tested
Answer:
The correct answer is "Provisioning services are disrupted by increased combustion of fossil fuels, which leads to an increase in air pollution".
Explanation:
The ecosystem provides several services that if used with responsibility, could be sustained by the nature. Unfortunately, disruption of an ecosystem service could happen by an anthropogenic activity, which are the activities that humans perform. One example is the disruption of provisioning services by increased combustion of fossil fuels, which leads to an increase in air pollution. The ecosystem provides clean air that gives oxygen for people and animals to breath, however high combustion of fossil fuels could disrupt this service.
If one has an esophageal cancer it is important to have a good nutrition.

A tube called J tube can be put in one's small intestine or G tube if put in a stomach. Parenteral nutrition can also be done if there is an intravenous drip.
Answer:
DNA replication is initiated by the help of these enzymes.
Explanation:
Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.
Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.
Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.
