Answer:

1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).

2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

C or E, the Iliac arteries are split from the descending aortic artery. They split in the pelvic following the left and right lower limbs. They then turn into the femoral arteries the run on the inside of your thigh along the inner part of your femur. However, the location that they split may be just right to also supply oxygenated blood to the reproductive organs.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan

Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>

Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
The correlation is that the more plants are present, the less carbon is free in the air.
The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

When neurons "fire," the first thing that happens is that sodium ions enter the cell. this does not require an input of energy.

Karo-lina-s [1.5K]

Answer;

One can infer that membrane transport proteins are required in order for neurons to fire.

Explanation;

Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.

-Transport proteins transport materials such as; ions such as sodium and potassium; sugars such as glucose; proteins and messenger molecules; and many more. In neurons, they play a fundamental role in the functioning of nerve cells. These transporters, a third class of membrane transport proteins, move a wide variety of ions and molecules across cell membranes.

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an

Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

Which is a difference between proteins and carbohydrates and fats?

morpeh [17]

Answer:

HERE JUST TAKE IT

Explanation:

Ok, there's carbon and hydrogen in all of them, that's the only similarity. They are known collectively as macro-nutrients.

Carbohydrates are basically, oxygen, carbon and hydrogen and they're the bodies primary source of energy. This means that they're the first source of energy used which is why if you eat foods high in simple sugars you get a sugar rush. All carbs metabolize down to glucose, some faster than others.

Fats are called lipids. Lipids are very heterogeneous (this means that there's not much similarity between them). Some examples of lipids are steroids, seed oils, pork fat, cholesterol, etc. The main thing in common with them is that they don't mix with water. They are readily stored in fat cells in the form of tryglicerides and are used when carbs are all used up. They also yield the highest per gram amount of energy (it escapes me right now).

In a chemical sense, fats are lipids derived from animals (saturated, solid at room temperature) and oils are derived from plants and seeds (insaturated with some exceptions, and liquid at room temperature. Insaturated are healthier because they contain HDL which cleans your arteries (prevents artherosclerosis).

Proteins are made up of aminoacids, 20 make up the vast amount of human proteins. Enzimes (the most famous being digestive enzimes) are proteins, skin is covered in protein, hair is protein, cilia and flagella are protein, basically EVERYTHING is protein, after water the human body is basically protein. They're only used up as energy when everything else is used up.

When athletes eat/drink protein, it's to give them building materials in order to increase the amount of stuff inside their cells which will enable them to produce more energy.
