That is true and cacti with many spines are typically preferred by parasites. This is an example of bidirectional selection in which evolutionary pressures from multiple sources encourage an organism to adapt.
The answer is water vapor.
When examining the transmission of phenylketonuria (PKU), a recessive trait, we can clearly identify the <u>genotype </u>when a child is afflicted with PKU. For the child not afflicted with PKU, we can only identify the <u>phenotype</u>, as the child may or may not be a carrier.
An organism's genotype is its particular aggregate of alleles for a given gene. So, for example, in the pea plants above, the feasible genotypes for the flower-color gene were pink-purple, red-white, and white-white. The phenotype is the bodily manifestation of an organism's allellic combination (genotype).
Someone's genotype is their precise sequence of DNA. Greater specifically, this term is used to consult the two alleles someone has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's scientific presentation.

The potential energy in food is what we call a Calorie, which (note the capitalization) is actually a kiloCalorie (1000 calories). Just pick any food high in calories; fats and oils are very calorie dense.
Explanation:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
