5 0

Answer: Precipitation

Grasslands are characterized as lands covered by grasses rather than large shrubs or trees. Grasslands are found in regions which receives rainfall that are not enough for the growth of forests. Desert covers about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Rainfall are least frequent in deserts as compared to grassland. The desert-grassland boundaries can change as a result of precipitation. The fate of land form of boundary will be dependent upon precipitation. As, if the boundary receives moderate or sufficient rainfall to grow vegetation then it will be included in the grassland and if the boundary receives no or scanty rainfall then boundary will be included in desert region.

"The ____ is the division of the autonomic nervous system that coordinates arousal and involves the expenditure of energy."
finlep [7]

Answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system is the part of the autonomic system of neurons which gets activated in the condition of stress.

The stress conditions activate the sympathetic nervous system which prepares the human body for the stress condition by either fight or flight mode.

The fight or flight responses requires a large amount of energy which are produced by the activation of the parasympathetic energy therefore the sympathetic system involves the expenditure of the energy. The system is also involved in sexual arousal.

Thus, the Sympathetic nervous system is the correct answer.

In this lab, we'll be using PCR to make many copies of a small region of your personal DNA genome. It is a very bad idea to touc
Luden [163]
Sounds like a trick question.

Maybe not. contamination is easy, but gloves are a barrier between other organic material on yourself (such as what you ate for lunch) and what you are testing.

Other than the fact your DNA will be different than another person’s DNA, if we assume you are theoretically free of debris of any kind, then your DNA would test the same always.

Note: any contamination after purifying extract for a small sequence can give false positives. There are repeat sequences possible that would interfere if you are testing a small enough sequence.

I hope that helps!

Another way is to have a lubrication to be applied in order to lessen the discomfort in which the client may have experienced.
