b)...AGC GAC AGC AGC AGC AGC AGC AAG T...
d)...CAC GGC GGC GGC GGC GGC ATC GC...
Explanation:
Trinucleotide repeat is a genetic mutation where a crack of three nucleotides is repeated, next to each other, so many times that it leaves the DNA molecule unstable.
This mutation is capable of causing errors in the reading of DNA, which results in disorders and syndromes in the affected organism.
The three strands of DNA shown above show this mutation.

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.
In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people—those who exercise every day for an hour and those who don’t exercise at all.
............................ In this case, the statement that people who exercise for an hoour may have lower cholesterol level is HYPOTHESIS. ....................... The cholesterol level would be the DEPENDENT VARIABLE.
An hypothesis refer to a proposed statement based on prior knowledge, which is used as a starting point in scientific experimentation.
In scientific experiments, there are always two variables, independent and the dependent variable. The independent variable is the variable that is changed or controlled in a scientific experiment in order to determine its effects on the dependent variable.

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.

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.
