Answer:
Increase
Explanation:
Visceral fat is a type of storage body fat. It is stored in the abdominal cavity and often surrounds many vital internal organs like stomach and liver. Over the time it forms a layer around these organs and also deposits in arteries which can cause many problems.
It can lead to insulin resistance which increases the risk for type 2 diabetes. It can also lead to other chronic conditions like heart disease and stroke. Hence, its increased amount is not good for the body. It can be decreased by proper diet, exercise and decreasing stress.
Answer:
Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin — a protein that carries oxygen in red blood cells. People with two copies of the sickle cell gene have the disease.

Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
Answer:
Specialized structures such as
1. The brightly colored flowers attract insects that transfer pollen from the anther to the stigma of another plant.
2. The scented smell of flowers and their nectars also attract insect and other pollinators to them.
Explanation:
Reproduction refers to the way by which plants and animals produce offspring or their types. Pollination, which is the transfer of pollen grains from the anther to the stigma of the same or another flower is a vital way by which plants accomplish this.
Structures of plants such as their brightly colored flowers, the nectars produced by them, as well as their characteristic smells attract pollinators to them that, in turn, aid reproduction.
