By all of the following ways bacteria become resistant to antibiotic except

Which of the following conditions represents a case of co-dominant genes?
A gene expresses itself, suppressing the phenotypic effect of its alleles
Genes that are similar in phenotypic effect when present separately, but when together interact to produce a different trait
Alleles, both of which interact to produce a trait, which may or may not resemble either of the parental types
Alleles, each of which produces an independent effect in a heterozygous condition
The first bioherbicide developed in 1981 was based on
Phytophthora palmivora
Phytophthora infestans
Bacillus thuringiensis
Azadirachta indica
Upon fertilization, what structure develops from carpel?
Testa
Tegmen
Pericarp
Perisperm
C.
Pericarp
Ripened ovary or fertilized ovary is called fruit. The wall of the ovary forms fleshy or dry fruit wall known as pericarp. It means that the pericarp is developed from pistil or carpel.
Testa is the hard external coating or integument of a seed.
Tegmen is a covering or integument, usually referring to a thin layer or membrane in an organism.
Perisperm in some seeds is a mass of nutritive material outside the embryo sac.
