Answer:
A. A biofilm
Explanation:
Biofilms have high bacterial density near to 10000000 CFU/ml bacteria. Due to such high densities, these biofilms becomes resistant to the antibiotics. These biofilms are basically community of microorganisms which stick itself to some kind of surface be it living or non-living. The bacteria’s which get attached to these biofilm and grow in an environment in which they possess both tolerance and resistance towards any bactericidal agent. Due to this functional mechanism of bacterias with in the biofilm, they become resistant to antibiotics.
A dihybrid cross tracks 2 genetic traits from 2 parents.
First you need to look at all the potential combinations of each parent
Parent 1: heterozygous tall & heterozygous round Tt & Rr
Parent 2: Homozygous dominant tall & wrinkled TT & rr
(use something like foil and look at all the possible options)
Parent 1: TR , tR, Tr, or tr
Parent 2: Tr
TR . tR . Tr tr
Tr . TT Rr . Tt Rr . TT rr Tt rr
Results show that 50% of offspring will be Tall & Round and 50% will be tall and wrinkled (phenotype)
however genotype displays a 1:1:1:1 ratio as none of the genotypes are exactly the same
The stem transports the water from the roots to the leaves
hope this helps!!!! <span />
