What roles do electrons and hydrogen ions play in the
light-dependent reactions of photosynthesis?

Answers

Answer 1

Answer:

Water is broken down into hydrogen ions, electrons, and oxygen gas. Electrons used for energy in photosynthesis but not for general cell needs. Electron energy is then used to make molecules that act as energy carriers.

Which best explains why it rains in the deserts less than other areas on Earth?
O A. Most deserts are in the hottest areas of the world and water cannot condense to form clouds
O B. Most deserts are bordered by oceans, which draw the water away from the land because of gravity.
O C. Most deserts are bordered by mountains that prevent the flow of atmospheric water into the regions.
O D. Most deserts exist in areas where people have overused water resources, preventing any water from staying on the ground long enough to be evaporated.

Answers

answer is O B, because it actually does rain in deserts, just much less than in other ecosystems.

Why are some crows not afraid of scarecrows?

Answer:

C

Explanation:

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?

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.

Not sure what you mean by understanding reflection but i'll do my best.

World War II was one of / if not the biggest tragedy to happen in modern history. It taught the world important lessons about society; that we need to work together and not let our differences enable another global conflict to the degree of WW2. However, history never completely repeats itself and while WW2 was a terrible and unimaginable tragedy, it provided us with information that can help us all in avoiding a future conflict similar in nature. However, how is the author so certain that history doesn't repeat itself? Have we not seen history do such thing. For example, there were vaccination protests all throughout history just like how there is vaccination protest today. So, I am interested in how the author came to his conclusion that WW2 will not inevitably repeat itself.

Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?

Answers

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.

breathing involves the movement of diaphragm and Rib cage



true or false​

Answers

Answer:

True

Explanation:

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!

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.

What happens when the chemical bond that holds the third phosphate is broken?

Answers

The chemical bond between the second and third phosphate groups is a high energy bond. When that bond is broken, energy is released, producing ADP (adenosine diphosphate).

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).
