Bacteria Growth Rate Formula:
N(t) = N(0) * ( 1 + r)^t
where, N(0) is the number of bacteria present at the beginning of the experiment, r is the growth rate, t is the time taken/ elapsed.
Substituting the numbers for N(t), N(0) and t from the given description, we get the value of r.
220 = 20*(1+r)^(24 hours)
Solving for r, we get r = 0.105074.
1 week has (7 x 24 = 168) hours in it.
Therefore, N(168 hours) = 20*(1+0.105074)^168
Which is approximately 390 millions.
Hence there will be 390 millions bacteria at the end of 1 week.
Answer:
c) degree of myelination of the axon
Explanation:
The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.
Nerve conduction velocity is specific to each individual and depend on the level to which that axon is myelinated, but also on an axon's diameter.
True,
genotypes are the genes of an organism for one specific trait
so without them you would not be able to predict the offspring thus defeating the purpose of the punnett square
Answer:
The appearance of an organism is the phenotype!
