Answer:

The correct answer will be option-pollen.

Explanation:

The pollen are the male gametophyte which is produced in the seed plants.

The pollen produce male gametes after entering the female gametophyte. The male gametes fuse with the egg cell and form the embryo inside ovary which matures and forms seeds.  The vascular seed plants lack these pollen but instead produces male gametes in gametangia which are replaced by the pollen in the seed plants.

Thus, option-pollen is the correct answer.

A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product. The model is based
lions [1.4K]

Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.

    The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.

The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

How will the enzymes in these bacteria most likely change if the temperature is lowered to 45
larisa [96]
The enzyme will likely be less affective or more affective, however, it depends on what the perfect temps tire is. since this sounds like it is lowering its temp from the “ideal range”, the enzyme will be less effective!
