macrophage are immune system cells that patrol the blood and body tissues. when a macrophage finds a foreign invader, the macrophage ingests (takes in) the foreign invader and then chemically digests (breaks down) that foreign invader. to perform this frequent chemical digestion, macrophage have more than the average body cell is

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.

Match the given behaviors of water with their correct rationale. Use your observations about water and the reading you have done
kap26 [50]

Answer:

Heat energy first breaks hydrogen bonds before it increases movement of water molecules - High specific heat

As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water- Ice floats on water

A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not - High heat of vaporization

Hydrogen bonds between water molecules keep the molecules "sticking together." - Cohesion

Explanation:

Water is a molecule composed of two atoms of hydrogen and one atom of oxygen. Water is a very unique substance with properties that are unexpected of a molecule its size. Some of the unique properties of water include:

Its high polar nature, High-specific heat, High heat of vaporization, the lower density of ice. One of the reason for these unique properties is strong cohesive forces between water molecules.

Cohesion: Hydrogen bonds between water molecules keep the molecules "sticking together."

Polarity: Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen because oxygen is more electronegative than hydrogen. As a result, water is a good polar solvent.

High specific heat: Heat energy first breaks hydrogen bonds before it increases movement of water molecules.

Lower density of ice: As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water, therefore, ice floats on water

High heat of vaporization: A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not.
