Answer:
Populations evolve, not individuals. ... Individual organisms do not evolve, they retain the same genes throughout their life. When a population is evolving, the ratio of different genetic types is changing -- each individual organism within a population does not change.
Answer:D
Explanation:
. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle.
Answer:
Explanation:
Folding can change the position in which rock layers appear. sometimes, layers of rock are overturned so frequently that the youngest rock layer may appear on the bottom, which is the reverse of what is ordinarily expected.
Answer:
The inner membrane of a mitochondria are made up of phosphoslipid bilayer just like all membranes surrounding animal cells. The bilayer is made up of hydrophobic tails which point inwards, and the hydrophilic layer pointing outwards away from the inner fluid layer. Thus entry of substances into and out of the cells cytoplasm are well regulated.
Layers of protein are embedded in the membrane to transport electron spitted from Hydrogen atoms deposited by FADH2 and NADH2 into the matrix. This set up gradient for the transport of electrons in chains called Electron Transport Chain.
The adaptive features of of inner membrane is its large surfaces areas to volume ratio to accommodate enough hydrogen ions / protons pumped by PMF, needed to set up electrochemical gradient for energy used by ATPase Synthase for ATPs production.
Enzymes are proteins. therefore the smaller units are amino Acids units are linked by polypeptides chains. Basically carboxyl group,Amino group, Hydrogen and R-group( which determines the nature of Amino Acids) are the basic functional group of Amino Acids.
Enzymes are globular proteins formed from confrontational change on the amino acids moiety ,
They are organic catalyst which speed up the rates of biochemical reactions in living organism.
Explanation:
Very small things on the order of micrometers/smaller that cannot be resolved with a light microscope. Things like viruses, non mitotic DNA, certain bacteria/cells can only be resolved via an electron microscope.
