If a fruit fly has four chromosomes then they would only pass on half of their chromosomes to the offspring. The new fly would have gotten 2 chromosomes from the father and 2 from the mother making it 4 chromosomes in total.
Answer: Erythropoiesis is the process which produces red blood cells (erythrocytes). It is stimulated by decreasing oxygen in circulation detected by the kidney which then secrete erythropoietin that proliferate and differentiate red blood precursors & produce red blood cells.
Explanation: The use of erythropoietin to boost red blood cells is called blood doping. The more red blood cells are present in the body, the more the energy expenditure and the slower you will burn calories during physical activities.
I just finished a topic in science on this.. lemme try my best:
4: PCR (Polymerase Chain Reaction)
5: Genetic Engineering
6: Restriction Enzymes (I think)
Let me know if I’m wrong!
Answer:
The correct answer is - C) pH paper + Phenol red.
Explanation:
Iodine is a reagent and indicator that is used to test confirm the presence of the starch in the sample by producing its characteristic blue-black color.
pH paper is an indicator that helps in telling about the pH level of a specific sample or solution by changing its color.
Biuret reagent is used to test for the presence of protein as it identifies peptide bonds in a solution.
Benedict's solution is an indicator that is used to confirm the presence of simple sugar in the solution or sample.
Phenol red solution is used as a pH scale to identifies the pH value of a sample or solution.
Sudan Iv is used to find the lipids and fats in the sample or solution.
Thus, the correct answer is - C) pH paper + Phenol red test for similar conditions.
