Answer:

Organisms depends on physical and biological factors of an ecosystem.

Explanation:

Biological and physical changes cause shift in an ecosystem's populations because the population of organisms depends and greatly affected from the environmental factors such as temperature, moisture etc. These environmental factors causes change in the physical features of an ecosystem so when these changes occur in physical factors, it greatly affected the population of organisms.

Why would it be important for epidemiologists, scientists who study the spread of disease, to determine patient zero?
amm1812

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.
