Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

What list is composed of substances widely used for many years without apparent ill effects?

balu736 [363]

The list that is composed of substances that are widely used for many years without apparent ill effects is the GRAS. GRAS is an abbreviation for generally recognized as safe; it is an American food and drug adminstration designation where chemical or substance added to food is considered safe by experts, and therefore, it is exempted from the usual federal food, drug, and cosmetic Act.

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.
