These are the organic molecules:
1) Organic molecules can be found in living organisms, but they can also be found in non-living things, such as petroleum and coal.
2) The four major groups of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.
3) Carbohydrates are molecules that contain carbon, hydrogen, and oxygen. They are the most abundant biomolecules in living organisms. Carbohydrates can be simple sugars, such as glucose, or complex carbohydrates, such as starch and cellulose.
4) Lipids are a diverse group of molecules that are also made of carbon, hydrogen, and oxygen. Lipids are not soluble in water, but they are soluble in organic solvents, such as alcohol and ether. Lipids can be used for energy storage, insulation, and protection.
5) Proteins are molecules that contain carbon, hydrogen, oxygen, and nitrogen. They are essential for life and are involved in a wide variety of functions, such as structure, metabolism, and cell signaling.
6) Proteins are composed of amino acids. Amino acids are molecules that contain an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R). The side chain varies from amino acid to amino acid and gives each amino acid its unique properties.
7) Linked amino acids form polypeptides. Polypeptides are chains of amino acids that are linked together by peptide bonds.
8) The two forms of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
9) Nucleic acids are composed of nucleotides. Nucleotides are molecules that contain a sugar, a phosphate group, and a nitrogenous base. The sugar in DNA is deoxyribose, while the sugar in RNA is ribose. The nitrogenous bases in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). The nitrogenous bases in RNA are adenine (A), guanine (G), cytosine (C), and uracil (U).
10) Nucleotides link together to make a nucleic acid through phosphodiester bonds. Phosphodiester bonds are formed between the phosphate group of one nucleotide and the sugar of the next nucleotide.
11) DNA and RNA are structurally different in several ways. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous bases adenine (A), guanine (G), cytosine (C), and thymine (T), while RNA contains the nitrogenous bases adenine (A), guanine (G), cytosine (C), and uracil (U).

Frog red blood cells have a nucleus that human red blood cells don't. This is because human RBCs eject their nucleus to allow more room for oxygen-carrying hemoglobin, while frog RBCs retain their nucleus potentially for environmental adaptability.
The organelle that frog red blood cells (RBCs) have, which human RBCs do not, is the nucleus. In mammals like humans, the nucleus is ejected from the RBCs as they mature to allow more space for hemoglobin, the protein that carries oxygen.
This makes human RBCs more efficient at oxygen transport. However, many amphibians like frogs retain the nucleus in their RBCs throughout their lifespan. The exact reason why frogs retain their nuclei is not entirely known. However, it might give the cells greater flexibility in responding to changes in the frog's environment.

Explanation:
They squeeze the bones.
B.
They cause bones to bend.
C.
They push bones apart through ligaments.
D.
Muscles contract and thus pull on bones to cause movement.
my guess is d ps idk what subject this is
Your answer is D. Muscles contract and thus pull on bones to cause movement.
recycled products on plant growth. Miguel’s lab
group compared the effect of different aged grass
compost on bean plants. Because decomposition is
necessary for release of nutrients, the group
hypothesized that older grass compost would produce
taller bean plants. Four flats containing the same
species of bean plants (25 plants/flat) were grown for
5 days. The plants were then fertilized with compost
as follows: (a) Flat A: 450 grams of two-month-old
compost; (b) Flat B: 450 grams of four-month-old
compost; (c) Flat C: 450 grams of six-month-old
compost; (d) Flat D: 0 grams of compost. The flats
of beans were planted in the same type of soil. The
plants received the same amount of sunlight and
water each day. At the end of 30 days, the group
recorded the height of the plants in centimeters. What is the flaw in this experiment?
