Those who can’t compete die or don’t have a chance to reproduce and pass on their traits (survival of the fittest). To survive and compete, an organism has to adapt to its environment
The answer is rice, wheat, and corn.
Croplands, rangelands and pastures, and fisheries and aquaculture provide an important supply of world's food. Nearly 80% of the world's food comes from croplands. People can eat about 50,000 plant species, but only 14 of them supply the majority of world's food. Of those 14, only three grains, and those are rice, wheat, and corn, are consumed by about two-thirds of the world's human population.

Explanation:
Drug Metabolism:
- Drug metabolism is divided into two steps: Phase 1 and Phase 2 reactions.
- Phase 1 reactions involve the degradation or formation of functional groups.
- Phase 2 reactions involve the conjugation of the drug or its Phase 1 intermediate with a polar conjugating molecule. Phase 2 generally performs the detoxification step in the drug degradation process.
- Phase 2 or conjugation reactions are further divided into 2 types:
- Type 1: Glucoronidation and sulfonation: An activated conjugating molecule such as glucoronic acid, sulfate or glutathione etc. is combined with the drug to form a conjugated molecule.
- Type 2: Amino acid conjugation: An activated drug or substrate is conjugated with an amino acid such as glycine or glutamine.
Glutathione Conjugation:
Glutathione is a tripeptide found in most tissues, particularly in the liver. It performs important detoxification functions for all cells. The enzyme, glutathione S-transferase conjugates glutathione with drug intermediates to form a drug-glutathione conjugate. This conjugate can easily be excreted through bile or urine.
Amino acid Conjugation:
This is an important reaction in xenobiotic biotransformation; particularly for xenobiotics with carboxylic group or an aromatic hydroxylamine groups. Drug intermediates combine with glycine or glutamine to form an amino acid conjugate.
It is much likely that the mother will suffer from pneumonia. Fetus is likely to suffer from birth defects known as varicella syndrome if it occurs at a gestation of 8-20 Wks (skin scaring, underdeveloped arms and legs, incomplete brain development)
if the infection is within 48yrs before a delivery child may suffer from neonatal varicella which is life-threatening
