Answer:

This hormone was made by a different cell, and it’s now being taken in by another cell using a steroid receptor. The steroid receptor is affecting the process of transcription in the nucleus so that a specific type of mRNA can exit the cell and form a new protein in the ribosomes. This formation wouldn’t be possible unless specialized cells were working together to perform this function.

Indeed, steroid hormones have an important role in the well-being of the individual through specialized cells (having specific receptors). Take the example of vitamin D.

Vitamin D is involved in calcium and phosphorus absorption by the intestines, as well as in their reabsorption by the kidneys. It is involved also in bone mineralization of the skeleton and joints, as well as on muscle tone.

The mechanism of action of the hormone is identical to the scheme:

Its carrier is vitamin D-binding protein

The cell may be an intestinal cell, bone cells or renal cells.

The vitamin acts on the DNA is activating / inhibiting certain genes encoding proteins so as to increase the level of calcium in blood.

1. The glutamate causes an influx of ca2+ ions into the nerve cell akin to what occurs during depolarization. However, this occurs excessively without regulation (due to excessive stimulation by the glutamate) that  eventually causes nerve injury through cytotoxic edema.



2. When the ca2+ levels are lowered during stroke, then nerve cell injury would be obviated hence enabling the chances of restoration of nerve cell function.   This would happen because there would be no excess calcium ions to influx when the NMDA receptors are excessively stimulated by the glutamate molecules.

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Which of the following statements correctly determines the process when following the scientific method?
crimeas [40]

Answer:

A) Formulate question,conduct research,propose hypothesis,test hypothesis

Explanation:

The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:

1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.

2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.

3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.

4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.

This seems to be the best answer: C. The data does not take into account underground growth and the actual area of fungus spread may be larger, so the original conclusion of the experiment is not accurate.
