The diagram shows changes of state between solid,
liquid, and gas. The atoms of a substance lose energy
during a change of state. After the change, the atoms
are close together but are able to slide past one
another.
Which arrow represents the change of state describes above ?
Answers
Answer:
Arrow O
Explanation:
The question states that the substance is starting out with high energy (gas) and lowers energy to something that is still able to "slide" or flow, a liquid.

Trace what happens to a piece of bread as it enters the mouth to the large intestine. Be sure to mention each organ of the digestive system and what happens to the bread in each part. ( can you put it in high school level)
Answers
Answer:
Bread is a carbohydrate.
Digestion of carbohydrates begin from the mouth.
As the bread is eaten and it is been chewed, the salivary amylase act on it.
This is also called mastication which is the breaking down of large pieces of bread into smaller pieces.
The salivary amylase break the monomeric bond between the dissacharides and starches by breaking amylose and amylopectin into smaller glucose.
When it's get to the stomach there is no further breaking down in the stomach because amylase do not get to the stomach because of stomach acidity. The strong peristaltic contraction of the stomach make it to form uniform chyme.
When the chyme entered the small intestine, the pancrease releases the pancreatic juice which contain amylase that breakdown dextrins into shorter carbohydrates. Additional enzymes are released which break maltose into two glucose and this enzyme is called maltase.
Sucrase breakdown sucrose into glucose and galactose.
There are cells in the small intestines which contain membranes that have protein transport which get monosaccharides and other nutrients to be absorbed in the blood.
The liver receive glucose, fructose and galactose and store them which is later use by the cells.
Explanation:
Digestion is the breakdown of large complex food into smaller pieces which can be easily absorbed by the body.
The goal of carbohydrates digestion is to breakdown complex carbohydrates and dissacharides into monosaccharide that can be absorbed into the body.

Dr. DeRidder lesions, or damages, the ventromedial hypothalamus in one group of rats and the lateral hypothalamus in another group. What effect might he expect on the eating behavior of each group of rats? Both groups should begin overeating and become grossly obese. Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating. Both groups should stop eating and perhaps eventually starve to death. Rats with ventromedial lesions should stop eating; rats with lateral lesions should begin overeating.
Answers
Answer:
Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating
Explanation:
The feeling of hunger stimulates a desire to eat.
The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.
A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.
On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.

Which is one place that glaciers are found?
A) in the ocean
B) in the tropics
C) at low altitudes
D) at high latitudes
Answers
Answer:
I believe it is at high latitudes
Explanation:
I say this because many glaciers are found in Greenland and Antarctica which are both located in higher latitudes
Glaciers are found at HIGH latitudes (Option D).
Latitude refers to the geographic coordinates which are used to indicate specific north-south positions on the Earth's planet.
Low latitudes are geographic coordinates found between the 0 degrees (Equator) and 30 degrees north-south, whereas high latitudes are found between 30 degrees and 90 degrees north-south positions.
At low latitudes, the energy from the sun is able to melt the polar ice.
Thus, glaciers are found at high latitudes because the highest latitudes get a minor amount of energy from the sun compared to low latitudes.
In conclusion, glaciers are found at HIGH latitudes (Option D).

Which of the following is mostly likely to result from an error during transcription A. it is formed by a particular sequence of amino acids B. it is read in groups of three nitrogenous bases C. it is made of the same components in all living organisms D. it is found in the base sequence of nucleic acids
Answers
Answer:
So I think you're trying to ask where transcription errors take place, which I would say is A.
Explanation:
DNA transcrption is when DNA is converted to RNA, which is then sent to ribosomes in the cell to make specific protiens(this is how viruses destroy cells, they use this system to make more viruses by causing viral RNA or DNA(transcripted)to be given to ribosomes) Anyway, transcritpion makes certain sequences of Amino acids for protiens, so an error is going to affect this area first, which can cause large systematic problems later.

Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all.
Answers
Answer:
C
Explanation:
The complete question: A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. In the experiment described in the scenario, which group represents the control group? A. Plant B B. Plant A C. Plant D D. Plant C?
The control group here would be plant D.
Control groups are usually used to minimize the effects of extraneous variables in the course of experiments and to ensure that the differences observed in different experimental groups are due to the effects of the independent variables.
In this case, all the plants were exposed to music except the control group because the aim of the experiment is to measure the effects of music on plant growth. Any difference in growth observed between those exposed to music and the control group can reliably be considered to be due to the music.
