Answer:
All the offsprings would be heterozygous purple colored flower
Explanation:
Given
Purple color flower is dominant over white color flower
Let the allele for purple color of flower be represented by "P"
and the allele for white color flower be represented by "p"
A pea plant that is homozygous purple-flowered is crossed with a pea plant that is white-flowered.
Genotype of homozygous purple-flower is "PP"
and Genotype of homozygous white-flower is "pp"
Cross between PP and pp produce the following offspring
PP * pp
Pp, Pp , Pp , Pp
All the offsprings would be heterozygous purple colored flower

β-lactam antibiotics are those antibiotic that that contain a beta-lactam ring (the cyclic amide with the nitrogen atom attached to the β-carbon) in their molecular structures. This class of antibiotics is the most commonly used and it includes penicillin derivatives, cephalosporins, monobactams, and carbapenems. The mechanism of action of β-lactam antibiotics is inhibition of cell wall biosynthesis in the bacteria.
