Natural selection is when the environment favors the best species that is likely to survive. It results in a survival of the fittest. The phenotype best adapted get to reproduce, whereas that species that is less well adapted fails. All of this occur
Where are the corresponding reactions likely to occur in prokaryotic respiration? The chemical reactions involved in respiration are virtually identical between prokaryotic and eukaryotic cells. In...
Correct answer is option A – Inner plasma membrane. Unlike the eukaryotic cell that synthesizes ATP primarily on the inner membrane of the mitochondria; prokaryotic cells synthesize ATP primarily on the inner plasma membrane. Remember, prokary
Which one would be expected to happen? If one of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that when placed in an aqueous...
The pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). In blood the ph is near to neutral. Human blood needs to keep its pH near 7.4, and avoid shifting significantly higher or lower – even if acidic or basic subst
Which option completes this sentence? The atomic number of carbon is 6.14C is heavier than 12C because the atomic nucleus of 14C contains _____________.
The correct answer to this question is B, six protons and eight neutrons. Protons are defined as a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite si
