Answers
Explanation:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.o
Reason – The two magnetic field lines do not intersect each other because if they do it means at the point of intersecting the compass needle is showing two different directions which are not possible.
HCl is acidic only when moist or aqueous. Hydrogen Chloride gas will turn blue litmus paper red only if either the gas is moist or the litmus paper is wet with some pure water. This is because when the gas comes into contact with the water on the paper, it becomes acidic, turning the litmus paper red.
