At higher concentrations, it catalyzes the collisions. think of it like a glow-stick. the smaller ones aren't a bright because less chemicals are inside the tube, but large glow-sticks are brighter, and has more chemicals contained in the tube. the correct answer is 3, the catalyst answer. <span>At higher concentrations, product molecules are able to catalyze the reaction.
hope this helped. good luck!

The red blood cells were placed into an isotonic solution. Water moved into and out of the cells to maintain homeostasis.
Answer:
the roots, and the have to get the right type of tempter from the sun so the leaves don't crinkle up and die.
Explanation:
<span>Age structure would help scientists determine if the problem exists with young or old dolphins.
The age structure shows the distribution of the ages of the individuals in a population. This not only shows the type of change taking place in the population (increasing, decreasing or staying the same) but also is able to help us relate problems to ages. By determining the which age group is more stressed, the scientists will be able to narrow down the causes of the stress and create more accurate hypotheses.

Answer:
Myogenic mechanisms
Hormones
Sympathetic nervous system
Explanation:
Myogenic mechanisms work in the arterioles that serve the glomerulus.
They cause the smooth muscle cells in the arterioles to contract and relax in response to blood pressure changes.
The sympathetic nervous system increases blood flow through the kidneys during resting conditions.
At times of stress, it decreases blood flow through the kidneys, making it more available to the rest of the body.
The hormones angiotensin and aldosterone regulate blood volume by controlling retention of Na⁺ and water.
C is wrong. The parasympathetic nervous system mainly controls visceral organs such as glands.
