Answer:
b. absence of peptidoglycans in the cell walls of archaea.
Explanation:
<em>Archaea is a domain of unicellular organism (procaryotes) that live in extreme environments, their cell walls are made of pseudo peptidoglycan (similar in function to peptidoglycans but different in structure), </em>on the other hand, bacteria's cell walls are made of peptidoglycan and lipopolysaccharide.

Biotic factors are those that are living in an ecosystem, such as plants and animals, while abiotic factors are those that are not, such as rocks, temperature, water, sunlight, soil etc.
C is correct for number 2 because broadleaf trees are a biotic factor, while precipitation, or rainwater, is abiotic.
A is incorrect because both are biotic factors, since both are living
B is incorrect because both are abiotic factors, since both are nonliving
D is incorrect because both are biotic factors, since both are living
Answer:
1. The reason there is energy released in the process is because the products formed (ADP and hydrogenphosphate/phosphate) have stronger covalent bonds (plus intermolecular forces with the surrounding solution and dissolved ions) than the starting materials.
2. The end product of oxidative phosphorylation is ATP and water. ATP synthesis is coupled with the transfer of electrons to O2, which combines with protons to form water. Phosphorylation is the chemical addition of a phosphoryl group (PO3-) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (there are enzymes involved). kinases and phosphatases, From the family of Enzymes.
