Answer:
Darwin was able to explain evolution with evidence, something Lamarck did not do.
Explanation:
Lamarck and Darwin both were scientists who tried to understand the concepts of evolution. Lamarck's theory of evolution was based upon how living organisms vary during their lifetime, and after that they pass these changes to their offspring. While on the other hand Darwin's theory was very much based upon evidences and practical explanation that is why his theory became accepted and Lamarck's wasn't.
Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.
