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)
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.

Which is a goal of the Human Genome Project?
a to identify the 3 billion genes that comprise the human genome
b to sequence the genome of every living individual
c to address the ethical consequences of genomic research
d to measure the length of human DNA
Answer:
C. to address the ethical consequences of genomic research
Explanation:
Option A comes very close to the correct answer but is not the main goal. Although the scientists were after decoding our genome and mapping our genes and such, ultimate goal was also to address the ethical consequences of genomic research because your genome is your blueprint (i.e. your genome makes you).
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
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.

The hydrolysis of GTP to GDP carried out by tubulin molecules Group of answer choices provides the energy needed for tubulin to polymerize. occurs because the pool of free GDP has run out. tips the balance in favor of microtubule assembly. allows the behavior of microtubules called dynamic instability.
Answer:
allows the behavior of microtubules called dynamic instability.
Explanation:
GTP help to stabilize the tip of the microtubule, thereby allowing more monomers to be added.
The hydrolyses of GTP to GDP carried out in the tubulin molecules allows the behavior of microtubules called dynamic instability.GTP hydrolysis changes the conformation of the tubulin molecules and cause the dynamic behavior of microtubules because it allows the cell to rapidly reorganize the cytoskeleton when necessary in which individual microtubules alternate between cycles of growth and shrinkage.

Explanation:
A heterozygous organism has
1.three different alleles for a trait
2. Two identical alleles for a trait
3. Only one allele for a trait
4. Two different alleles for a trait
I'm completely sure your answer would be D.
It has two different alleles for a trait!
An organism that is heterozygous has two different alleles for the same trait. Therefore, the correct option is B.
Alleles are genetic variants that affect the way a trait is expressed in different ways. During sexual reproduction an organism receives one allele from each parent. If these alleles disagree, the organism is said to be heterozygous for that trait. Two different alleles enable genetic diversity and the possibility of different phenotypic outcomes. A dominant allele may be expressed as a result of heterozygosity, while the effect of a recessive allele may be obscured. This genetic diversity is important for evolution because it gives rise to natural selection and the ability to adapt to changing conditions.
Therefore, the correct option is B.

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.
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.
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.
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.
The correct option is C.

Which statement accurately describes dark matter? It is the same as dark energy. It is well understood by scientists. It does not emit electromagnetic radiation. It can be observed by shifts in red and blue light.
Answer:
Dark matter does not emit electromagnetic radiation.
Explanation:
Dark matter comparative to dark energy, has various differences. You could say that dark energy is put into action on a larger scale than dark matter, which is also why dark energy makes up 74 percent of the universe. Thus, dark matter ≠ dark energy.
Scientists have a lot to learn about dark matter, so we can't claim that this subject has been well understood about scientists. In fact, it is one of the least understood parts of the universe!
_______________________________________________________
Now dark matter can be defined as particles that do not absorb, reflect, or emit light. Thus, it can't be observed by electromagnetic radiation - nor shifts in red and blue light. At the same time it does not emit electromagnetic radiation.
