Macrophages are immune system cells that are vital to the development of non-specific defense mechanisms that provide the first line of defense against pathogens. These large immune cells are present in nearly all tissues and actively remove dead and damaged cells, bacteria, cancerous cells, and cellular debris from the body.

What is Macrophages?

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.

A model of a gene, DNA, and a chromosome is shown here. A researcher tags the gene with a heavy radioactive isotope (P-32). Whic
adoni [48]

Answer:

The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes

Explanation:

Genes are made of DNA, but there are many (numerous) genes found along chromosomes. Only a small portion of the chromosome will be radiolabeled.

Which of four factors that affect evolution apply to the finches that the Grants studied?
harkovskaia [24]

Answer:

The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.

When a potassium ion (K+) moves from the soil into the vacuole of a cell on the surface of a root, itmust pass through several c
goldfiish [28.3K]

Answer:

C. primary cell wall → plasma membrane → cytoplasm → vacuole.

Explanation:

Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.
