Is their and All Of The Above
Cuz it all happens
The answer is c because u have look at the picture very clearly.
Answer:
Natural selection by directional selection, was the driving force of evolution at work. The purple flowers parents were able to withstand the selective pressure and therefore emerged from completions with other flowers from previous generation, thus their dominance follow directional selection. This was the trait inherited by their offspring, the dominant purple
The gene pool of purple flower will be large; because of dominance in expression with each successive generation in both homozygote and heterozygote state, and therefore higher frequency of expression compared to the white flowers.
The frequency of allele depends on the rate expression of the allele in the population. Thus, the dominant purple flowers have high frequency of expression compared to the recessive white flowers which can only express itself in homozygote recessive state
Answer: A. Archaea lack peptidoglycan.
Species of bacteria are named gram-positive because of their positive respond towards gram staining technique. These bacteria retain the crystal violet dye and are colored pink or purple because of the presence of thick layer of peptidoglycan in their cell walls, whereas the gram-negative bacteria has thin layer of peptidoglycan hence, cannot retain the stain of the dye. Archaea species do not possess peptidoglycan in their cell wall, therefore will give negative response to gram staining technique, hence, there are no gram-positive Archaea species.
Answer: Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
