Final answer:

A carbohydrate is an organic molecule consisting of C, H, and O atoms in a 1:2:1 ratio, important for human biochemistry and found in various forms from simple sugars to complex polysaccharides.

Explanation:

An organic molecule that consists of carbon (C), hydrogen (H), and oxygen (O) atoms in a 1:2:1 ratio is known as a carbohydrate. Carbohydrates are essential biomolecules that come in various forms, such as sugars, starches, and fibers.

They have a general stoichiometric formula of (CH₂O)ₙ, where 'n' represents the number of carbon atoms in the molecule.

These organic compounds are a significant part of human biochemistry, consisting of carbon and hydrogen, and are essential for our diet and bodily functions.

Simple carbohydrates include monosaccharides like glucose and fructose, while complex carbohydrates include polysaccharides such as starch and cellulose.

The carbon skeleton of a carbohydrate provides a backbone to which other functional groups are bound, making them versatile in structure and function within living organisms.

LOTS OF POINTS!!!!!!!! What is a Physical and Chemical Reaction?

Answers

Answer:

See explanation.

Explanation:

In a chemical reaction, the substances change. Put hydrogen and oxygen together and the chemical reaction results in water.

A physical reaction there is a change in form, but the chemical composition remains the same. Take water below freezing, and ice forms - a physical reaction.

Answer:

Explanation:

In a chemical reaction, the substances change all together and there is no going back you cant take them apart.

A physical reaction there is a changes, but the chemical composition dosnt. this one you can go back from it becuse the chemical reaction didnt change.

How are fish adapted to their environment? ( Science Fusion)

Answers

Fish have adapted to the environment by learning to use its fins and gills underwater.
They have streamlined bodies, a lateral line system for gathering sensory input on both sides of the body, a mucus/slime coating to cover scales, thus helping to move faster in water. Some use incredible camoflauge to bkend in with their surroundings. Fins help them to steer, swim, stabilize.

How does meiosis I differ from meiosis II?A) The sister chromatids separate during meiosis I, but not during meiosis II.
B) The homologous chromosomes pair up during meiosis II, but not during meiosis I.
C) Two sex cells are produced as a result of meiosis II, but not as a result of meiosis I.
D) Chromosome number decreases by half as a result of meiosis I, but not as a result of meiosis II.

Answers

Option D is correct, I believe that option A is wrong because in meosis 1 sister chromatids are together option B is wrong because homologous chromosomes are in meiosis 1 not 2 option C is wrong because 4 sex cells are produced in the process of meosis 2
