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).

Answer:
how do i actually answer you bro? there are so many questions
circulatory; immune
B)
endocrine; lympathic
C)
circulatory; excretory
Eliminate
D)
circulatory; respiratory
Answer: The correct answer for the fill in the blank is A) Circulatory, immune.
Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.
Blood contains different cells like white blood cells, red blood cells, platelets.
White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
B. tree roots growing downward because of gravity
C. sunflowers turning toward light
D. vines curling around a fence
I AM THinking b but im not sure
One example that is not a behavioral adaptation in plants is tree roots growing downward because of gravity. The correct option is B.
Behavioral adaptation is what creatures do to survive. If we are talking about animals, the behavior can be acquired and carried down over generations, or it can be an innate adaption, which entails adaptions being passed down through generations genetically.
Individual organisms or entire groups can benefit from behavioral adaptations. Behavioral adaptations are actions taken by a plant to increase its chances of survival. Tropisms are an example of a behavioral adaptation in plants. Tropism refers to plant growth toward sunlight.
Roots growing downward due to gravity is not an adaptation because it is a natural cause, adaptations are the ones that save them from extreme conditions.
Therefore, the correct option is B.
