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

Biology

boyakko [2]2 years ago

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.

Is the possession of flagellated sperm a primitive or advanced characteristic in the plant kingdom?
Triss [41]
The possession of flagellated sperm is considered a primitive characteristic in the plant kingdom. A flagellated sperm has a special characteristic called flagellum, which enables the sperm to propel and swim in the water. Plants who live in water have flagellated sperm since their sperm needs to swim to reach the eggs. More evolved plant species are terrestrial, therefore their sperm is transferred to the eggs through the air or pollinating insects. At this evolutionary stage, the sperm of the plant lost its flagellum.

vesna_86 [32]

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Explanation:

On the islands, Charles Darwin discovered several species of finches. He found out that different species of finches varied from island to island. Besides elaborating his thoughts on natural selection, this also helped him in his investigation on the evolutionary changes of the finches.  Beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti. Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits. Shorter, stouter beaks served best for eating seeds found on the ground.
