Answer: A scientific theory is a well-substantiated explanation of such facts. The facts of evolution come from observational evidence of current processes, from imperfections in organisms recording historical common descent, and from transitions in the fossil record.
Explanation:
How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
two types of variables
Answer:Independant and Dependant?
Explanation:
I'm not sure but those are two types
True or false: If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
False.
Correct statement: A rancher uses a particular chicken for breeding purposes because,on average,she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of selective breeding.
What are all living organisms on earth called
Answer:

whats the difference between the lipid structure and the carbohydrate structure
Lipids are an important element of the cell membrane. The structure is usually composed of a glycerol backbone.
Carbohydrates, it's very literal: are “hydrates of carbon” and possess the general structure of C(n)H(2n)O(n).
Lipid molecules comprise more energy per gram than carbohydrates: close to two times as much.Carbohydrates are more readily ingested than lipids and discharge their energy more quickly. Monosaccharides and disaccharides are water-soluble and are less complicated to move to and from storage places than lipids.Animals manage to apply carbohydrates fundamentally for short-term energy storage, while lipids are applied more for long-term energy storage. Carbohydrates are stored as glycogen in creatures while lipids are stored as fats. In plants, carbohydrates are stored as cellulose and lipids as greases.Lipids have less impact on osmotic force inside a cell than complex carbohydrates.Largest gland in human body

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
Which of the following conclusions is most likely to be CORRECT?
A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

The brain stem consists of the ________. Group of answer choices midbrain, medulla, and pons cerebrum, pons, midbrain, and medulla midbrain only pons, medulla, cerebellum, and midbrain
Hey there! I'm happy to help!
The cerebellum is in the back of the brain and it helps with balance and reflexes, but it isn't part of the actual brain stem, so that is not the right answer choice.
The cerebrum is the front part of the brain made up of the many different lobes. Its ultimate goal is to help with thought, movement, and language. This is not part of the brain stem.
The brain stem consists of the midbrain, medulla, and pons. The midbrain is the uppermost part with the pons below it and the medulla oblongata below the pons.
The midbrain is important for functions such as eye and body movement. The pons aids with body signaling and the medulla oblongata also aids with reflexes and involuntary actions (as it is close to the cerebellum). The brain stem as a whole helps with respiration, heart rate, and blood pressure.

Explanation:
As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

the best anatomical term to describe the back region of the body would be
Ventral, gluteal, deep, or dorsal?
Hey there! I'm happy to help!
Ventral has to do with the front side of the body. The ventriloquism (controlling a puppet and talking without your lips without moving to give the illusion that the puppet is talking), it has to do with creating an illusion from the front side of your body. It comes from a Latin word that means "belly", so something like ventriloquism is "belly speaking". The ventricles of the heart are chambers that are closer to the belly. So, this is not referring to the back region of body and is incorrect.
Gluteal has to do with the gluteus maximus muscles. This is a specific section of the back region of the body and not the actual back region as a whole, so this is incorrect.
Deep just means that something is further inside your body (further from the skin). For example most of your bones are deep to your muscles. This is the incorrect answer.
You may have heard of a dorsal fin on a fish or shark. These fins are normally on the top of a fish. This is the same thing as being on their back because their bellies (ventral, front) are facing down. This term does apply to the back region of the body, so this is correct.
The best anatomical term to describe the back region of the body would be dorsal.
