_____________________________________

Answer:

Mutations:

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

_____________________________________

DELETION:

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

_____________________________________

DUPLICATION:

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

_____________________________________

SUBSTITUTION MUTATION:

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

INSERTION MUTATION:

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

_____________________________________

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid. Option A is correct because B and D are wrong as increase in number of bases and decrease in number of bases is because of deletion and duplication mutations here it asks for substitution and insertion mutations. C is wrong as In mutation there is always a change in bases or chromosome. So all the other choices seem incorrect as it is asking for substitution and insertion the base pair changes which results in the change in type of amino acid.

Is oxygen always necessary for the production of ATP in your cells?

Answers

Yes. Part of cellular respiration (ATP making) is the ETC (electron transport chain). As the hydrogen ions move throughout the ETC, it eventually comes to a close. Just as if a whole bunch of cars were driving on the road, and the light turned red, all the cars would have to stop. The same is for the electrons. Thus, oxygen is REQUIRED to keep the ETC flowing. If the ETC can flow, then the organism can go. That hydrogen ion (electron) bonds with the oxygen to make...water!

That water than powers the ETC in plants for photosynthesis, by the splitting of water. Then that released oxygen is used in CR!

I’m working on a cell project that is focusing on the nucleus and I have to find a theme song for it. Any suggestions about songs that might relate to the function of a nucleus?

Answers

Answer:

https://youtu.be/tRo73dzVfuo

A good song that could serve as a theme song for your cell project is;

The Nucleus Song, sung by Megan and Sarah

The song above can serve as a good background for your cell project. It can be gotten from the mainstream video blog under the name Craigdet.

This song is a good choice because its lyrics mention the various parts of the cell, like the ribosomes, endoplasmic reticulum, cytoplasm, etc., and their functions.

It also mentions and displays the nucleus and its role in the cell. The song is educative and entertaining. It will be a good fit for your project.

36. What are the functions of proteins?
37. What foods contain high amounts of protein?
38. What are the four levels of structure found in proteins?

Answers

30.Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups.

31.Lipids are detected using the emulsion test. This is what happens: The test substance is mixed with 2 cm 3 of ethanol. An equal volume of distilled water is added.

32.In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements. Proteins serve a variety of roles in living organisms and are often classified by these biological roles.

33.amino acids

For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein

34.Peptide Bonds

Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).

35.A polypeptide is a single linear chain of many amino acids (any length), held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty).

Answer:B. Sugar are produced

Explanation: when green leaves absorb sunlight it is converted to Energy by photosynthesis.

Answer:

I'm pretty sure it's C.

Explanation:

Plants don't get to warm unless they don't have oxygen, sugars are produced, but only during all of photosynthesis, and green leaves don't turn red unless the season is changing. But sun light gives chlorophyll what it needs to produce that green color. Therefor, C is your answer.

How do I write a essay using the digestive urinary and excretory system to maintain homeostasis.

Answers

Homeostasis is balance. The shortest answer to your essay is that these 3 systems remove toxins from the body. Some of these toxins are in the air & food we take in, and some are just waste products after we process food.

The digestive system takes the food we eat, pulls out the energy we need to move and live, and passes on the waste to be excreted. If it didn’t excrete the waste, toxins would build up in the body.

The urinary system maintains homeostasis by filtering toxins out of the blood, and deciding how much water should be retained or wasted, based on our blood’s chemistry.

Another part of the excretory system is our skin. We sweat out toxins from exercise.

I hope these ideas are helpful to get to through your essay.
