The Krebs cycle occurs in the <span>matrix of mitochondria. It is one of the main processes of creating energy for the organism.</span>
Answer:
active transport require energy to move molecule across a cell.
Explanation:
There are 27 x 10⁷ cells in total for the given conditions of cell culture.
Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.
Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-
75 x 12 = 900 ml
Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-
900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells

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.
