They help bring about chemical reactions.
A.) The phenotype is yellow, smooth
This is because (Y) yellow is dominant over (y) green. If an organism has a trait that is dominant, it will show up with no exceptions (YY, Yy, Ss, SS). Recessive traits on the other hand will only show up if both the maternal (Mom) and the paternal (Dad) copy given are both recessive (yy or ss).
b.) It depends on what the YySs plant is paired with. Will it be paired with another YySs, with YYSS, yyss, YySS, yySS, YYss...? For example, if it is paired with another YySs, make a punnett square.
Answer:
trench
Explanation:
Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. This process results in the formation of a trench. The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates. The deepest part of this trench, called the Challenger Deep, is over 36,000 feet deep, deeper than Mount Everest is tall.
<u>Answer</u>: As the growth rate increases, the population size increases more rapidly. The slope becomes steeper.
An increasing growth rate means that more and more of the offspring will survive. Thus, this leads to a cumulative effect in which with an increasing growth rate, the slope becomes steeper.
If in the beginning only 1 out of 10 offspring will survive (r=0.1), then the population will increase with only one individual. However, if r=0.5 then 5 new individuals will be added. These in turn will be able to reproduce themselves with even higher r, which results in the cumulative effect mentioned above. The more individuals survive and the higher r, the faster the population size will increase.
No ecosystem is capable of sustaining such a growth for long periods of time. The population will reach and exceed a level called carrying capacity, which is the maximum number of individuals the ecosystem can sustain. Once this happens, the growth rate will be negative until the population size is once more under this level.
From now on, the population will vary around the carrying capacity with r switching from positive to negative in a continuous cycle. Furthermore, if this level is exceeded very much, then currently available resources will be consumed and thus the population size will plummet back to extremely low levels.
Locust swarms are a good example. The population size increases rapidly and devours all available food. If no more food can be found, then the majority of the individuals will die of starvation.
Answer:
A)Use restriction enzymes to cut the DNA at specific sequence sites.
Explanation:
Restriction enzymes cut DNA in specific sites. There are high and low frequency endonucleases. The easiest to get fragments to make the words: WILL YOU MARRY ME? is to amplify PCR fragments of known size and sequence, therefore, use restriction enzymes to cut the fragments of the desired size. It will be very useful make an in silico digestion to predict all the fragment sizes to be obtained, and a simulation of the gel before loading it.
