1. Proteins are made from subunits called amino acids. There are 20 different amino acids which are responsible for the variation of proteins. Those amino acids are linked together by peptide bonds and form polypeptide chains. According to the polypeptide structure, there are 4 levels in protein structure as primary structure, secondary structure, tertiary structure and quaternary structure.
2. Starch is a type of carbohydrate. Hence, the subunits of starch are sugar molecules which are called as glucose. The elements of glucose are C,H,O. By linking glucose units with 1-4 alpha glycosidic bonds, the polysaccharide chain is formed. Hence, starch is also a polysaccharide<span>.

3. DNA is made from subunits called nucleotides. Nucleotides consist of deoxyribose, phosphate group and nitrogenous base.
There are two types of nitrogenous base as purines and pyrimidines. Adenine (A) and guanine (G) are purines and
thymine (T) and cytosine (C) can be seen as pyrimidines. Those nucleotides are linked together by sugar phosphate bonds which are formed between 5' phosphate group and 3' -OH group<span>.</span><span>

<span>NADH and FADH2 are part of the Calvin cyle, so A and B are incorrect. I'm not sure, but I think that cytochrome C to oxygen has to do with cell division. The correct answer is D, the electrons are passed from reduced ubiquinone (QH2) to cytochrome, C, one at a time.</span>
Answer:
D)clues about the past climate of Earth
Explanation:
The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never be found.
Answer:
Medications that can increase the chances of getting a fungal infection
Budesonide (Entocort EC)
Cortisone (Cortone)
Dexamethasone (Decadron)
Hydrocortisone (Cortef)
Methylprednisolone (Medrol)
Prednisolone (Prelone)
Prednisone (Deltasone)
Triamcinolone.
They are both made up of protons,neutrons and elements
