Answer:
D. Increased sunlight and increased nutrients will increase phytoplankton populations.
Explanation:
Both sunlight and nutrients are required by phytoplankton communities. We know that <u>phytoplanktons</u> are <u>primary producers</u> and they produce food via <u>photosynthetic activities</u>. To carry out photosynthesis, <u>presence of (inorganic) nutrients and sunlight is highly important</u>. In this process, energy is fixed in energy rich molecules such as glucose and organism multiply and/or gain biomass. A decrease in any of them will result into reduced photosynthesis and hence reduced phytoplankton population growth.
The answer is there (3). This is because a mitochondrion has it own DNA called mitochondrial DNA. Therefore the three genetic materials from different parents (mitochondria from donor mother, DNA from biological mother and DNA from biological father) would be present in the baby. Somatic nucleus transfer is the medical procedure used when the biological mother has mitochondria disorder which she would not wish to pass to her offsprings (which are inherited maternally).

Answer:
d. UAC
Explanation:
An anticodon, present on tRNA, is the complementary sequence to a determined codon on the mRNA. tRNA is responsible for placing the aminoacids in the correct order when a protein is being translated, and it does so by complementary binding the codons on the mRNA. Each tRNA can hold a different aminoacid, so, for example, the codon AUG encodes the aminoacid methionine, and this means that only a tRNA that has an anticodon with the sequence UAC will be able to hold metionine and place it on its position on the protein sequence.
