Answer:
2 unit
Explanation:
According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.
Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.
that is 2000→200→20→2
note: only 10% of the total biomass is received by the next trophic level.
therefore tertiary consumers will receive 2 units of biomass.
Answer: During fertilization, an egg with haploid number of chromosomes unites with a sperm cell with a haploid number of chromosomes to form a zygote with a diploid number of chromosomes.
Explanation: Fertilization is a process in which a sperm cell from a male fuses with an egg from a woman to form a zygote. Sperm cells and eggs are diploid cells and they have half the number of chromosomes as the parent cell. During fertilization the haploid chromosomes from the sperm cells combine with the haploid chromosomes from egg to form a zygote with diploid chromosomes. Diploid cells have the same number of chromosomes as the parent cell. Haploid cells are produced in meiosis while diploid cells are produced in mitosis.
Because it is not the dominant allele, it is the recessive allele so it is not shown.
