Answer:
"T" X "t" yields offspring that are all heterozygous with genotype "Tt"
Explanation:
An Allele refers to either of a pair of contrasting genes.
So, "TT" being the same yeild just one allele (T), while "tt" also yield one allele (t)
So, the cross of the both alleles
"T" X "t"
yields offspring that are all heterozygous with genotype "Tt"
Thus, the crossing dominant tall plant height "TT" and recessive short plant height "tt" yielded heterozygous tall plants "Tt"
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
