The decreasing wolf populations in North America can result to the <span>range expansion of coyotes
</span><span></span>Wolves and coyotes usually compete for prey, especially the smaller mammals. Wolves do not actively hunt coyotes but do attack them when the latter ventures into their territory.
With decreasing wolf populations, coyotes can then venture and hunt more freely. However, the coyotes cannot take the place of the wolves in helping maintain balance in the ecosystem in which they belong to because of their preference for smaller mammals.
Wolves can help regulate an ecosystem's larger mammals such as the ungulate populations, as they do not prey on the smaller mammals as much as coyotes do. This leaves more prey available for mid-level carnivores like foxes. Moreover, wolves also leave behind carcasses of their prey, which become food for other animals such as <span>foxes, badgers, raptors, coyotes and other scavengers.</span>
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.
Answer:
Insertion and deletion
Explanation:
A frameshift mutation is when the entire reading frame of DNA is shifted, and incorrect.
Frameshift mutations can either be caused by insertion or deletion.
When insertion or deletion occur, a nonsense protein will be made.
So, the correct answer is insertion and deletion.
Answer: living things such as “human beings”, “animals”, “plants”, and “microorganisms”.. Nonliving things do no exhibit any characteristics
Explanation: Nonliving things do not grow,respire, need energy, move, reproduce, evolve, or maintain homeostasis. They are made up of non living materials
