List and briefly describe four components of innate immunity (include one barrier defense and three internal defenses)
boyakko [2]

Answer: See the explanation below, please.

Explanation:

The immune system allows us to discriminate from the outsider.

There is innate immunity which we carry from birth and protects us against antigens; correspond to barriers that prevent harmful bodies from entering the body.

It is composed of some of these components:

- Skin and mucous membranes (physical barrier): the skin has microorganisms that inhibit the growth of pathogens.

-NK cells (natural killer): they are leukocytes that recognize changes in the cell surface of cells infected by viruses and tumor cells. These target cells are recognized by NK cells, which trigger cytotoxic response and destroy them.

- Neutrophils: white balloons with granules that release enzymes that destroy and digest cells.

-Cytokines (including interleukins 1 and 6, interferons, tumor necrosis factor: TNF): they are low molecular weight proteins that generate immune system response by recruiting or inhibiting the functions of specific cells (dendritic cells) or neutrophils, regulate proliferation and cell differentiation, activate or inhibit the expression of some genes.

What effect does insulin have on the body? It raises blood-sugar levels. It lowers blood-sugar levels. It raises glucagon levels
olchik [2.2K]

it regulates blood sugar level.

Explanation:

Insulin helps control blood glucose ( sugar) levels by signaling the liver and muscle and fat cells to take in glucose ( sugar) from the blood. Insulin therefore helps cells to take in glucose (sugar) to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose ( sugar) and store it as glycogen.

The lionfish are disrupting the marine food chain because there are no known predators. If you were a scientist working on this
Phoenix [80]
Since the lion fish became the apex predator in the controlled environment, I will balance the cycle by adding a (1) new predator which typically feeds on a lion fish and (2) another predatoir which preys on the predator which eats lion fish and preys on lionfish (which unquestionably preys on the lionfishes' prey too). 

This method is effective because in every experiment, there is always a control. The control speciment will be the predator which preys on the lionfish. 

Development can be noted if and only if the populatyion of the lionfish is decreased. If it happened and it will happen, the population of the two predators I added will be decreased proportional to the number of the lionfishes around. 

Using integral calculus: <span>Exponential Growth and </span><span>Decay, we will be able to track down clearly the population of each species in the controlled environment.</span>
