Answer:
pests can evolve defenses against pesticides over time
Explanation:
Pesticides are chemicals employed to kill pests generally. With continuous and indiscriminate use of pesticides, they become less effective because pests population often evolve a defense mechanism against them.
<em>With each usage, more and more pest population survive. Those that survive gradually multiply and pass the survival gene to their offspring eventually giving rise to a population that is genetically insusceptible to the effects of the pesticide. This is generally referred to as evolution by natural selection.</em>
Answer:
(i) Small island
(ii) Large island
(iii) Option-3
Explanation:
In the given question, the three population of the Anoles Lizards migrated to three islands of different size.
(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.
(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.
(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.
This phase is metaphase, and you can remember this by seeing the m means middle.
The chromosomal combination allows for each sex cell that is going to be produced to have different DNA combinations, allowing for the offspring to be not only different from the parents, but also allows for genetic diversity.
Answer:
ATP releases energy stored within the molecule by the procedure known as ATP hydrolysis. In the hydrolysis of ATP, the energy gathered in the high-energy phosphoanhydride bonds in ATP gets discharged due to the dissociation of these bonds, like in muscles, where work is generated in the form of mechanical energy.
The products formed in the process are inorganic phosphate and ADP. This ADP can get further dissociated to produce AMP and another orthophosphate.
