A. types of plants
B. quantity of plants
C. number of small animals
D. type of predators
Answer:
B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.
Explanation:
According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.
Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.
Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.
The correct option is B.
Is there like options in this question?
Answer:
No.
Explanation:
Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.
Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.
<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>
