Enzymes are biological catalysts<span> that carry out thousands of chemical reactions, which occur in living cells. Enzymes are large protein molecules with specific three-dimensional structures. Each enzyme </span>catalyzes<span> a specific </span>reaction<span>, or specific type of </span>reaction<span>, that involves specific substrates.</span>
Answer:
Actually, habitat change affects organisms. An organism must be able to adapt to changes in the environment or move to another location, otherwise it will die. Organisms have physical and behavioral adaptations that enable them to survive in their habitat.
Explanation:
Answer:
Positive feedback.
Explanation:
An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.
Stimulus causes an action or response, like the ringing of your alarm clock if you didn't sleep through it. Stimulus is a word often used in biology — something that causes a reaction in an organ or cell, for example. ... For more than one stimulus, use stimuli, not stimuluses.
I'm assuming that by elements, you mean the elements in the periodic table. In that case, the elements form complex compounds in plants and animals which are essential to their survival.
For example, sugars like glucose are used to provide energy which is used for various activities in plants and animals, especially active transport.
