Answer:

COAL

Explanation:

Secondary energy refers to the more convenient forms of energy which are transformed from other, primary, energy sources through energy conversion processes. Examples are electricity, which is transformed from primary sources such as coal, raw oil, fuel oil, natural gas, wind, sun, streaming water, nuclear power, gasoline etc., but also refined fuels such as gasoline or synthetic fuels such as hydrogen fuels.

Write a paragraph on how Blood Glucose goes with Negative Feedback
vagabundo [1.1K]

Answer:

Here are some explanations from 0nline so if you want rewrite in your own words

hope this helps  :))

blood glucose-

"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."

"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."

body temperature-

" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."

"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."

"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."

"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"

Cross a mother who carries the hemophilia gene but does not express it, With a father with hemophilia
alisha [4.7K]

Answer: The cross will produce 4 offsprings with the following genotypes:

XhXh, XhX, XhY and XY.

Explanation: Hemophilia is an X-linked disease. A woman who carries the hemophilia gene but doesn't not express it is heterozygous, therefore she has a genotype of XhX, and a man who has hemophilia has a genotype of XhY. A cross between them will produce one female and one male who are hemophilic (XhXh and XhY), one female who is a carrier (XhX) and one normal male.

See the punnett square attached for the cross
