Answer:
Glutamate Hippocampus, Frontal lobe, Sympathetic nervous system Cerebellum and GABA increases the performance during exam.
Explanation:
Glutamate, Hippocampus and Frontal lobe are the factors which help him in the preparation for successfully taking the exam because all these factors are linked to memory and we know that good memory gives good results in the examination. Sympathetic nervous system, Cerebellum and gamma-Aminobutyric acid (GABA) have a great impact on the Jackson's performance on the day of the exam because Sympathetic nervous system sends extra blood to the muscles when there is stressful situation while Cerebellum helps in the coordination of the muscles i. e. helps in movement of muscles such as for writing. Gamma-Aminobutyric acid (GABA) is eaten orally due to relieving the anxiety during stressful condition.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
Answer: option C) negatively charged and contains less sodium
Explanation:
In the absence of any stimulus, a neuron is said to be resting. During this time, more positively charged potassium ions (K+) than sodium ions (Na+) occupy the interior of its cell membrane, whereas more sodium ions than potassium occupies the exterior - making the cell membrane to be electrically Polarized with net positive charge outside and a net negative charge inside the cell membrane.
Thus, the interior is negatively charged and contains less sodium ions
Answer:
A. Salamanders
Explanation:
Specialists species are species that can thrive in a unique and limited range of resources. They require a specific environmental condition to reproduce and survive in environment and also have limited or few diets they need for nutrition. These limiting characteristics put them at a disadvantage of being endangered and threatened.
Salamanders are endangered species that are fast going into extinction. They require wetland (freshwater pools) for reproduction to be possible, and feed mainly on insects. This makes them specialist species.
Ospreys, snapping turtles, and beavers are all generalist species. They can all thrive in a wide range of environmental conditions, and also have varieties of diets they can get nutrition from to survive.
It would be A because plants use photosynthesis to make proteins and fats to kind of survive
