I believe the answer is C) How does a change in temperature affect the reproduction of crayfish?
The concentration of H+ ion (pH) could influence the structure of protein, which might inactivate some enzyme of an organism and alter their metabolism. All research questions beside option C is related to the pH. Buffer solution will provide an protection that will makes the pH become more stable. Acid rain contains acid which will decrease the pH of the surrounding environment.
Answer:
humans killing whales caused orcas to have to eat otters which caused sea urchin populations to increase which caused kelp populations to decrease
Explanation:
The energy that is used in organisms is: ATP
The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.
Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.
For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.
