Because plants go through a cycle(the cycle is seed, seedling, plant, flower and tree.) and it takes time for the plant food, water, and nutrients to go though the plant.
Abiotic factors are the greater part of the non-living things in a biological community. Both biotic and abiotic factors are identified with each other in a biological community, and in the event that one component is changed or expelled, it can influence the whole environment. Abiotic variables are particularly vital on the grounds that they specifically influence how living beings survive.
It all depends on the species, some lose all of their leaves for part of the year while others lose their leaves before the next growing season, retaining some during winter or dry periods.
Answer:
b. Bacteria with the desired plasmid produce white colonies.
Explanation:
The bacterial lacZ gene is usually used as a reporter gene, which encodes beta-galactosidase, an enzyme that breakdown lactose but can also breakdown a colourless synthetic analog X-gal, thereby producing blue colonies on X-gal–containing media. But the lacZ will be disabled when the recombinant DNA is spliced into the plasmid. This is because the LacZ protein will not be produced when the gene is disabled. Thus, X-gal will not be broken down and white colonies will be produced, which can then be separated and identified.
