I think the answer is B lil bruh
The answer would be letter a
Answer:
Haploid number of chromosomes.
Explanation:
Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.
Don't listen to the other answer (if it's still there) the answer is C. Winter
Answer and explanation;
-The most important life processes in the oceans or sea water are photosynthesis and respiration. Photosynthesis by plants and other lower organisms uses sunlight to convert CO2 and H2O to a carbohydrate compound; O2 is a by-product of that reaction. Respiration is the process that all organisms use to recover the chemical energy stored in organic compounds. O2 is used to oxidize organic matter and release chemical energy; CO2 and H2O are by-products.
-The rates of photosynthesis and respiration are nearly balanced.all of the organic matter produced by photosynthetic algae is respired by consumer and decomposing organisms.
