<em>D. The release of oxytocin in response to stretching of the uterus.</em>
Explanation:
There are two types of feedback loops, negative and positive.
Negative feedback loops' main goal is to maintain homeostasis, or equilibrium within the body. When there is a stimulus, the negative feedback loop will try to make the output less than it is, to make homeostasis equal again. An example of this would be regulating blood sugar. If your blood sugar levels are low, your body will release glucagon to make them higher, that is a negative feedback loop.
Positive feedback loops' main goal is to make the reactions go by more quickly, it makes the equilibrium unstable while accelerating the reaction. An example of this would be releasing chemicals in the body such as oxytocin, during childbirth to make it less painful and to speed up the process.

Answer:
d. He did not but instead proposed an erroneous evolutionary mechanism known today as inheritance of acquired characteristics.
Explanation:
Lamarck believed that organism changes as the environment change, and that those changes are passed to offspring ( inheritance of acquired characteristics). He also believed that if a certain structure isn't used by an organism it will gradually disappear through time.
According to Darwin's theory of evolution, natural selection is the main evolutionary mechanism. Darwin explains that organisms that have heritable traits that help them survive and reproduce, will be favorable by natural selection. Those favorable traits will enable organism to better adapt to their environment and to pass more genes on to the next generation (offspring).
Organisms adapt to their environment by changing their behavior, structural traits or physiology as a response to environmental change, so that they become well suited to it.
It reflects all other colors of light therefore except blue. All the spectrums of the light get reflected back.
