Answer:
The independient variable in this study is the memory-enhancing drug that Dr. Bonne DeMuth is testing on the students.
Explanation:
In research studies, there are independent variables which are those that are being studied and analyzed. When these variables are intervened, these will be the ones that will directly affect the results.
So , in this case Dr Bonne DeMuth is trying to find out if a memory-enhancing drug would help decrease the time it takes students to learn how to trace a maze.The independent variable in this case would be the drug analyzed by Dr Bonne DeMuth and the intervention that is being carried out on this variable is to know if it can achieve the desired effect(decrease the time it takes students to learn how to trace a maze).
Answer:
Food production will increasingly be impacted by climate change, in particular from the increased frequency of storms, droughts and other extreme weather events. Food production is in turn a major contributor to greenhouse gas emissions as well as water scarcity and wider biodiversity issues.

Answer:
I think that it is A. Smooth Muscles but i could be wrong
Explanation:
Smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically. (Found on g o o g l e)
Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium.
Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control.
