Which statement about endotherms and ectotherms is correct?
ankoles [38]

Answer:

3.  Endotherms spend more energy on internal temperature regulation compared to ectotherms.

Explanation:

Ectotherms, are considered  as cold-blooded animals (reptiles and amphibians),  and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.

Endotherms also called warm blooded animals  (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.

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.

Which water cycle processes usually cause a lowering in the water table? Which processes cause a rise?
olga55 [171]

Answer:

During the summer months, the water table tends to fall, due in part to plants taking up water from the soil surface before it can reach the water table. The water table level is also influenced by human extraction of groundwater using wells; groundwater is pumped out for drinking water and to irrigate farmland.
