Answer:
True
Explanation:
A DNA molecule is composed of the nitrogenous bases stacked inside the two backbones made up of the phosphate and sugar molecules. The nitrogenous bases form the nucleotide which when read in the triplets called codons code for specific amino acid and then form proteins.
If we say that we have to protect the DNA than it means that we have to conserve the DNA molecule. Conserving the DNA molecule means that the sequence of nucleotide which codes for specific proteins must be conserved as it is the protein molecule that is essential for survival.
Thus, true is correct.
All the trophic levels are there, Number ten is asking you to find a chain that includes 7 organisms. Starting from:
Phytoplankton (Producer)
Herbivorous Zooplankton (Primary Consumer)
Carnivorous Zooplankton (Primary Con.)
Artic Char (secondary Con.)
Capelin (tertiary Con.)
Harbor Seal (Quaternary Con.)
Polar Bear(Quaternary Con.)
Answer:
Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)
Heterozygous B: BB (h0m0zygous)
AO x BB --> AB, BO
Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.
