Answer:
A). Organisms within a population compete with each other to survive.
Explanation:
Charles Darwin in his evolution theory proposed that the organisms of all species emerge and develop via the 'natural selection' of tiny, inherited discrepancies and these disparities enhance the individual's ability to contest and compete with each other in order to survive and reproduce to continue their existence. This led to the emergence of the phrase 'survival of the fittest' which suggests that in this competition of 'natural selection', only the fittest will survive. Thus, <u>option A</u> is the correct answer.
Answer: the answer is B
Explanation: Yellow bone marrow is involved in the storage of fats. The fats in yellow bone marrow are stored in cells called adipocytes.
Answer:
(b) inhibition of ATP synthesis
Explanation:
The inner mitochondrial membrane is impermeable to protons. Electron transfer from NADH and FADH2 to molecular oxygen via electron transport chain generates electrochemical gradient by pumping the protons from matrix to intermembrane space. This electrochemical gradient drives ATP synthesis by down the concentration gradient transport of protons back to the matrix via proton channels.
A compound able to carry protons back to the mitochondrial matrix would dissipate the electrochemical gradient. In the absence of proton concentration gradient across the inner mitochondrial membrane, ATP synthesis would stop.
Answer:
raised atmospheric concentrations of CO2 by 47% above pre-industrial levels
Explanation:
Over the past 170 years, human activities have raised atmospheric concentrations of CO2 by 47% above pre-industrial levels found in 1850. This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm).
it would be Active transport .
