Volgvan3 years ago
6 0

Answer:

Some wastes e.g. gases easily diffuse out of the plant tissues

- Some waste products are mainly made from carbohydrate and hence are not as harmful as proteinases materials

-Some waste products are formed slowly thus little accumulation of wastes

- Plants are less active

- Some waste products such as Oxygen are reused or recycled

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.

During an interphase lasting 23 hours the S stage takes average 8.0 hours.What is the percentage of interphase is taken up by S
Alik [6]

The right answer is 34.78%

The interphase is the period of the cell cycle that the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:

* phase G1

* phase S: during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.

* phase G2.

Phase G1 is the longest phase of the interphase (its duration depends on the type of cell), followed by phase S, then phase G2.

To calculate the proportion of phase S in the interphase simply make the division:

phase duration S / interphase duration = 8/23 = 0.3478 (in percentage that is 34.78% (0.3478*100)).
