Answer:
Option C, It can regulate temperature
Explanation:
Carbon atom is able to form bonds with other carbon atoms or atoms of hydrogen , oxygen , nitrogen , phosphorus etc. A carbon forms a diamond/graphite when it joins cohesively while they form molecules like hydrocarbons, CO2 etc, when it joins adhesively with other than carbon atoms. Thus Option A is incorrect
Since carbon combines with other chemical atoms to form polymers, lipids , proteins etc, as they are adhesive to other than carbon atoms. Option B is also incorrect.
Option C, is a physical phenomena in which carbon compounds do not allow heat to escape from earth and in this way it regulate the temperature of earth. This is not an internal property of carbon and hence option C is correct.
Option D is incorrect as carbon can be easily decomposed along with production of energy by decomposers or by burning the fuels containing carbon.
Pepsin functions best in acidic environments and is often found in an acidic environment, particularly those with a pH of 1.5 to 2".
"Trypsins have an optimal operating pH of about 8".
It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5
Answer:
hope this makes sense
Explanation:
In an experiment, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: The difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group.
respiration provides energy for cells without using oxygen
They squeeze the bones.
B.
They cause bones to bend.
C.
They push bones apart through ligaments.
D.
Muscles contract and thus pull on bones to cause movement.
my guess is d ps idk what subject this is
Your answer is D. Muscles contract and thus pull on bones to cause movement.
