Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signal
Dimas [21]

Answer:

Nervous tissue can generate and conduct <u>electrical</u> signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

<em>     The other options are not true because nerve tissue does not generate or conduct </em><em>thermal </em><em>or</em><em> chemical </em><em>signals to perform its function.</em>

What would you expect to happen to levels of mevalonate in human plasma if an individual were to go from a meat-containing diet
enyata [817]

Answer:

increase

Explanation:

The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.

iren [92.7K]

Answer:

Adaption is a gradual process of change or modifications of animal body either physically, structurally or behavioral changes in order to thrive and adjust better in the changing environment for survival.

Explanation:

Adaptation could takes by exhibiting a sort of mimicry to the habitat in which the animal thrive. Also it could takes place by the process of structural changes that blends them well with the environment. Classical Example is the adaptation by Polar bear. In the coolest arctic region, polar bear possesses long white furs with big sized paws and long hair. This help them to blend with white snowy color of environment and the big sized paws prevents them from slipping in ice and also could dig in the ice to take shelter is hostile weather like snowstorm. They have thick layers of fat beneath the skin that keeps them warm. Also they are capable of swimming , in spite of a big body to facilitate their feeding on fishes on arctic sea.
