The correct answer is "a steroid hormone that reduces the amount of fluid excreted in the urine".
Aldosterone is a steroid hormone produced in the adrenal gland, whose main function is the homeostatic regulation of the blood pressure, plasma sodium, and plasma potassium levels.
Aldosterone's main mechanism of action is to regulate the reabsorption of sodium and excretion of potassium in the kidney, which in turn influences the retention of water and the volume and pressure of the blood. Based on all this, aldosterone reduces the amount of fluid excreted in the urine.

Within an infected wound bed, many cell types are involved in protecting the host and eliminating the "foreign invaders" to prom

Oxana [17]

Explanation:

All vital organs begin to lose some functionality as one ages during adulthood. Aging changes occur in all cells, tissues and organs of the body and affect the functioning of all body systems.

The living tissue is made up of cells. There are many different types of cells, but they all have the same basic structure. Tissues are layers of similar cells that fulfill a specific function. Different types of tissues group together to form organs.

There are four basic types of tissue:

The connective tissue supports the other tissues and joins them. This includes bone, blood and lymphatic tissue, in addition to the tissues that provide support and structure to the skin and internal organs.

The epithelial tissue provides coverage for the superficial and deeper layers of the body. The skin and lining of the ducts inside the body, such as the gastrointestinal system, are made of epithelial tissue.

Muscle tissue includes three types of tissue:

Striated muscles, such as those that move the skeleton (also called voluntary muscles)

Smooth muscles (also called involuntary muscles), such as the contents in the stomach and other internal organs

Myocardium, which makes up most of the wall of the heart (also an involuntary muscle)

Nervous tissue is composed of nerve cells (neurons) and is used to carry messages to and from different parts of the body. The brain, spinal cord and peripheral nerves are composed of nerve tissue.

An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in which function?

PilotLPTM [1.2K]

An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in CELL TO CELL RECOGNITION.
Carbohydrates have diverse functions, one of their functions is that they serve as a recognition signal at the surface of cells.
Carbohydrates located on the surface of cells enable cells to recognize and communicate with one another.

Avery and DNA (page 289)

Ivan

Yes, Avery, Mc Leod and Mc Carty do thought that genes may be involved in the transformation of non virulent rough Strains of <em>Diplococcus pneumoniae</em> to harmful smooth strained bacteria

<h3><u>Explanation:</u></h3>

Avery was a Canadian medical researcher who along with other two well known scientists of the contemporary time went for an experiment where he took two strains of bacteria Diplococcus pneumoniae - one is rough and nonvirulent and another is smooth and virulent. For a control run, he injected both the bacteria in separate mice and the expected result was there. Now as he injected heat killed smooth bacteria, the mice survived. But as he injected heat killed smooth bacteria with rough bacteria, although there was no organism which can kill the mice the mice died. And autopsy revealed the presence of live smooth bacteria in the lungs.

Thus they suspected something have gone from the dead smooth bacteria into the non virulent rough bacteria which lead to transformation of the rough bacteria to smooth ones. Thus, the experiment was carried on, which suspected role of genes in this transformation.

Some fungal species can kill herbivores while feeding off of sugars from its plant host. What type of relationship does this fun

LenKa [72]

Answer:

parasitism

Explanation:

In evolutionary ecology, parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life.
