The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.
Hope I helped you!
Answer:
translation and transcription
Explanation:
no. 1 is to do with energy in plants
no. 2 is cell reproduction
no. 3 is cell evolution
Answer:
CFU/mL
Explanation:
Given -
a) Number of colonies of bacteria is equal to 
b) Total volume of the solution is equal to
mL
c) Dilution factor is equal to 
As we know that
CFU/mL 
Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume
Substituting the given values in above equation, we get -
CFU/mL 
The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.
