Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Answer: Option B) Photosynthesis
Explanation:
It is impossible for plants to release energy from glucose using photosynthesis because photosynthesis results in the formation of sugar molecules such as glucose.
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
From the equation, photosynthesis is seen to as a biosynthethic reaction not a catabolic one.
Thus, it produces energy-rich compounds like glucose not otherwise
Hi!
The correct option is B. Which genes are active.
Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.
But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.
Hope this helps!
