Answer:
ATP molecules
Explanation:
Density centrifugation is a method that separates components of a sample on the basis of their density or density gradient.
During centrifugation the sample will be layered according to their density and that is the principle of density centrifugation.
When centrifuging a sample containing homogenized cells. ATP molecules will be found at the top of the centrifugation gradient due to having a lighter density compared to the rest of the molecules.
<span>Carbohydrates
Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.<span> </span></span>
I think it is B because horses now have flat teeth, while horses back then had sharper teeth, I think. Tell me if I am wrong.
Answer:
humans use their knowledge to locate resources.
Explanation:
The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.
The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.
brainiess plsssss
