The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
C) Renal pelvis is the part of the kidney that acts as a funnel to pass the urine that is produced in several nephrons to the ureters.
I think false because no one knows what will happen in the future and anything is possible, although the population does increase it can still decrease by high amounts aswell, anything bad could happen any time. People may not even have money to survive but it really depends on what happens and what could happen in the future, no one really knows what will happen so this statement would be false.
Anyway have a nice day :)
