A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.

Answer:
A in explanation
Explanation: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Stroma, in a biological explanation, the fluid in between grana, where carbohydrate formation reactions occur in the chloroplast of plant cells photosynthesizing.
Explanation:
Part A
In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.
Part B
In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.
Part C
There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
