Diffusion is simply particles spreading around. Think of it like spraying perfume in a room. Where the person sprayed the perfume would be a high concentration as there is a lot of that perfume there. However, on the other side of the room there would be little to no perfume. So the perfume spreads around until it is evenly distributed in the room.
The sequence of mRNA for a DNA strand AACGTAACG will be UUGCAUUGC.
Central dogma can be described as a process by which information in the DNA is transcribed into mRNA and then changed into proteins.
For a strand of DNA, a complementary mRNA strand is made in order to decode the information in this strand of DNA into mRNA.
The pairing is done as follows: Adenine pairs with Uracil, and Guanine pairs with Cytosine for forming the mRNA transcripts. The nucleotide thymine is absent in mRNA.
Hence, for the strand AACGTAACG, the mRNA strand will be UUGCAUUGC.

The answer is either A, the bottleneck effect or C, natural selection. The answer is most likely A because it is hinted that the predator fish was placed in the isolated stream. The predators eating the darters less than 5cm is natural selection though.
Answer: D
Explanation:
If you look it shows the order in the sentence.
Answer:
C) reception, transduction, and response
Explanation:
Plant signaling means that information is conveyed from receptor systems to effectors within and between plant cells.
Signals can be of chemical form or electrical form.
Plant responses to internal and external signals take place in the following sequence:
Reception
Transduction
Response
So, option C) is correct
