Both prokaryotic and eukaryotic cells use RNA polymerase to turn certain genes on or off. The correct option is A.
What is RNA polymerase?RNA polymerase, or more specifically DNA-directed/dependent RNA polymerase, is a molecular biology enzyme that synthesizes RNA from a DNA template.
The RNA polymerase enzyme is a large complex composed of many subunits. The prokaryotic RNA polymerase has four subunits that can transcribing all types of RNA.
These enzymes in eukaryotes have eight or more subunits that aid in the attachment and processing of DNA during transcription.
RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is a molecular biology enzyme that synthesizes RNA from a DNA template.
RNA polymerase is used by both prokaryotic and eukaryotic cells to turn genes on and off.
Thus, the correct option is A.

Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?
Answers
Answer:
Genotype of night blind woman - XnXn
Genotype of normal man - XY
Explanation:
Given
Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive
In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect
Genotype of night blind woman - XnXn
Genotype of normal man - XY

what are the merit of
indigenous education
Answers
Answer:
It was a way to protect, preserve and develop traditional indigenous skills and cultures. Education was a significant step towards empowering indigenous peoples to participate more fully in their communities. It was an indispensable asset to attain freedom and social justice.
Answer:
The core of indigenous education in Africa focused on providing each individual in the community with knowledge, practical skills and attitudes in order to prepare them to for his/her role in the society. It is a holistic system, in which apprenticeship, story telling, proverbs and myths played an important role. Traditional education developed in the ‘learners’ a sense of obligation towards the community and made learners to appreciate the history, language,customs and values of the tribal group, keeping in touch with their heritage, their cultural roots. Western education alienates young Africans from their cultural heritage.

2. 2,3-bisphosphoglycerate is an allosteric inhibitor of oxygen binding to hemoglobin. a. Acclimatization to high altitude involves numerous physiological and biochemical changes, including an increase in the concentration of 2,3-bisphosphoglycerate in red blood cells. Explain why the 2,3 bisphosphoglycerate concentration increases at high altitude. b. The 2,3-bisphosphoglycerate concentration in maternal red blood cells also increases during pregnancy. Why
Answers
Answer:
A. At high altitude, increase in 2,3-bisphosphoglycerate (BPG) ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.
Explanation:
Atmospheric pressure is low at high altitudes with the result that oxygen molecules in the air are further apart. The reduction of oxygen availability in the air thus reduces the oxygen saturation in the blood and brain. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
2,3-bisphosphoglycerate (BPG) is an allosteric inhibitor of oxygen binding to hemoglobin. At low concentration, oxygen delivery to tissues is low while at hgh concentrations, oxygen delivery to tissues increases. It ensures that oxygen bound to hemoglobin in blood from the lungs is delivered to the tissues. Thus, at high altitude, increase in BPG ensures that enough oxygen is delivered to the tissues despite the low oxygen saturation levels there.
B. During pregnancy, there is a significant increase in oxygen demand. This is due to a 15% increase in the metabolic rate and a 20% increased consumption of oxygen as the developing fetus obtains nutrients and oxygen from the mother's blood.
An increase in 2,3-bisphosphoglycerate (BPG) is necessary during pregnancy as it ensures that both the pregnant woman and developing fetus have enough oxygen for their metabolic needs.
