Answer:
Negative feed back control
Explanation:
Hormone secretion I the body system are normally control by negative feed back.
The secretion of Cortisol by the adrenal gland suppresses further secretion of ACTH by the anterior pituitary gland interaction is called negative feedback control because a stimulus causes the release of a substance which has effects that inhibit further release of hormone. This cause cortisol hormone Concentration in the blood to be maintained within a narrow range.
It causes the reduction of its own production i.e cortisol.

Monosaccharides (simple sugars) are also called carbohydrates. Using what you have noticed and learned about the elements in monosaccharides and ratios of the elements, explain why the term carbohydrate is an appropriate term for this group of compounds.
Answer:
Carbohydrate is one of major macromolecule and nutrient that is required for the energy and structure of body of almost every organism. These contains three elements that are carbon, hydrogen and oxygen in the ratio of 1:2:1. The general formula of carbohydrates is Cm(H20)n, in complex sugars m and n can be different.
Monosaccharides are simple sugars basic unit of disaccharides and polysaccharides. the ratio of carbon, hydrogen and oxygen are 1:2:1. As chemical level, they contain carbon, hydrogen and oxygen so termed as carbohydrates.

Thus, the correct answer is - flatworms and roundworms.
What information did you include in your answer? Check all that apply. uranium-lead (U-Pb) dating relative chronology expected effect of additional similar results on mass-extinction hypothesis connection between the use of new technology and a possible revision in the mass-extinction hypothesis identification of the use of the new technology as a new experimental method
Answer: D connection between the use of new technology and a possible revision in the mass extinction hypothesis
E identification of the use of new technology as a new experimental method
Explanation:
The connection between the use of new technology and a possible revision in the mass extinction hypothesis and identification of the use of new technology as a new experimental method is the information to include in an answer. So the correct options are D and E.
What is a hypothesis?
Repeated experimentation and observation have been used to devise scientific theories. These theories have been further referred to by peer reviews before they have been generally accepted by the scientific community.
Science involves methods and data that make sense of the world. The methods of principles are internally-consistent and well described. The progression from a hypothesis to a theory can only be through testable, scientific laws. There are only a few scientific facts that are natural laws as well but there are many hypotheses that can be tested to generate a theory.
Therefore, the correct options are D and E.

answer fastttt!!!!!Start with argon in a gaseous state. Manipulate the heat variable to change it to a
liquid, then a solid. Explain what you did to make this happen:
Answer:
By lowering the temperature.
Explanation:
Argon is a gas at room temperature. By changing its state from gas into liquid, we have to lower the temperature up to -185.7 degree Celsius while to change its state from liquid to solid, we have to lower the temperature up to -189.2 degree Celsius. There are two process occurs such as condensation and solidification, in condensation, argon gas is converted into liquid while in solidification, liquid argon is converted into solid.
2 Describe why it would be an advantage for the seeds
to be able to grow at any angle
Answer:
If plants could grow at any angle, resources could be better used, less labor would be spent, and crop production would increase.
Explanation:
By growing at different angles, crops could be generated in different locations that would not normally be beneficial or feasible for plant growth.
For this reason, land use would be higher for farmers as harvests would increase by making better use of the land and generating ideas to make better use of resources.
They could be better used, for example, a scale cultivation on a sloping terrain, no time would have to be spent flattening the ground and only the crops would have to be cared for.

An engineer wants to build a house on a beach. Buildings on the shore must be built high enough to avoid flooding from oceans during storms. The highest wave height elevation measured for storms in the area is 15 feet. The support beams must reach a depth of 7 feet underground. Based on scientific knowledge, which of these support beams would be the best to use for the building?
Answer:
Answer B
Explanation:
Because i got it correct
Answer:
Support Beams 25 feet or greater
Explanation:
Not only is this the common sense game but the highest wave height is 15 feet, because the beams must reach a depth of 7 feet underground.
15+7 = 22 feet
To avoid the highest wave it must be at least 22 feet.

Fluoxitine is given to a client at a dosage of 500 mg every 6 hours. Assuming that the half-life of this drug is 3 hours, at what point would the drug level in the body be 62.5 mg of the original dose?
Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
