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.

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.
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.

Corundum is a mineral with a hardness of 9 on the Mohs hardness scale. For which application would corundum most likely be useful?
Answer: It can be used for grinding optical glass.
Explanation: This is because it is so much harder than glass.
Being a hard mineral, Corundum is most likely to be useful in the cutting of gemstones, grinding optical glasses, and grinding vehicles wheels.
What do you mean by Corundum?Corundum may be defined as a mineral that is very hard and consists of aluminum oxide occurring in massive and crystalline forms, that can be synthesized, and is used for gemstones.
The extreme hardness of corundum makes it more useful and unique in the field of metal polishing, metal grinding, optical glasses grinding, etc.
Therefore, being a hard mineral, Corundum is most likely to be useful in the cutting of gemstones, grinding optical glasses, and grinding vehicles wheels.

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.

A blood sample contains several different types of cells, each of which contains different combinations of specific ions and molecules. The cells are suspended in water, and the water also contains many molecules and ions. Which term or terms could be used to describe this sample of blood
Answer:
A mixture,which is heterogeneous because it is made up of different solutes or components which are not uniform.Therefore when the mixture described in the question are viewed,the cells,ions,molecules mixed together varied from one region to another leaving phases(2 or more) that are separated from one another,with each components still retaining their original properties for easy identification.When these samples are taken out they show variation in their proportion of the components.
Thus blood cells will have their different phase,like wise,water,plasma, etc.
It is different from homogeneous mixture in which the components are uniform and appear in the same proportion,in one phase.
Note-the part of a sample mixture with the same properties and composition is called a phase.
