breathing involves the movement of diaphragm and Rib cage
true or false
Answer:
TrueExplanation:
It's a true statement as,
When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.
Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!
Hope this explains better :)

5. What is the difference between impotence and infertility?
Answer:
Impotence, which is another word for erectile dysfunction, simply refers to difficulty getting or keeping an erection that's firm enough for sexual activity. Sterility or infertility means that the body doesn't produce “good” sperm—that is, not enough sperm are produced, or the sperm don't function as they should.
A _________ is an organic compound that must be obtained from the diet and is needed to sustain life.
A Carbohydrate is an organic compound that must be obtained from a balanced diet
Carbohydrates are food nutrients which are also organic compounds which are required for the sustenance of life because they are a very vital source of energy which the body requires for it to function properly and efficiently.
Other organic compounds are Proteins, lipids and Vitamins because they all contain elements of carbon in them. But for the Human body to be active it requires energy and the most important source of energy to the body is Carbohydrate
Hence we can conclude that Carbohydrate is an organic compound that must be obtained from a balanced diet.

Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
Answer:
vaccines basically have the virus they are fighting in them to get the white blood cells in our bodies to know how to fight that virus in the case we do get it
Explanation:
Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

What happens when the chemical bond that holds the third phosphate is broken?
The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).
What is phosphate bond?
The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.
This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.
Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.
Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Amino acids are named after two of their functional groups: the amino group (NH2), which acts like a base, and the carboxyl group (COOH), which acts like an acid. Amino acids also contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH3). In serine, the R group is a methyl alcohol (–CH2OH).
A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.
What functional groups will be joined together if alanine and serine molecules combine to form a single molecule?
A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.
A. an amino group and a carboxyl group
B. two amino groups
C. an amino group and a methyl group
D. a hydrogen atom and an methyl group
The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.
What is amino acids?Amino acids are molecules that join together to form proteins. Amino acids are the building blocks of living organisms. Proteins are broken down into amino acids which is the end product of protein digestion and it is easily absorbed into the body. Amino acids help to build cells, synthesize hormone and neurotransmitters.
Amino acid is divided into essential and non essential amino acids.
The essential amino acids are not synthesised by the body but they are taken up as food supplements and they include that include leucine, isoleucine, histidine, lysine, methionine, threonine, phenylalanine, tryptophan, and valine.
Non-Essential Amino Acids are Amino acids that are synthesised by our bodies. Examples include aspartic acid, glutamic acid, alanine, glycine, tyrosine, serine.
Therefore, The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.
