believe the correct answer from the choices listed above is option A. The two principal ways to describe Earth’s structure are based on the chemical composition and thickness of layers. Since Earth is a layered structure, it is viewed according to its different chemical composition and the thickness.
1. A mudslide wipes out the side of a thriving hill: This is negative as many trees and other organisms will get destroyed.
2. A volcano erupts, covering the nearby land with lava: This is negative as molten and extremely hot lava can cause serious damage to its surroundings.
3. A forest is rapidly growing new plant life: This is positive because new plants are being grown.
4. Humans remove wolves from a national park to protect surrounding homes: This is positive for humans because humans will be safe but it is negative for the eco system as removal of wolves can upset the eco system cycle.
5. A dam is built in the middle of a river ecosystem to supply water to a nearby town: This is positive for humans as a new water resource is being developed for humans but negative for aquatic organisms as the dam can hamper their ecosystem and can cause pollution in water.
Answer:
Option A
Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.
This is an example of repetition.
Repetition is an important literary device since it allows a speaker or a writer to put emphasis on items they choose to be significant. it is an important tool for authors and speakers in developing style, tone, and rhythm. It tells the audience or the reader that the words that are being used are central enough to be repeated, and also lets them know when to pay a special attention to the language.
The atmospheric pressure drops so the partial pressure of O2 drops proportionately. The hemoglobin must circulate faster to deliver the same quantity of oxygen to working muscles' mitochondria for cellular respiration. This increased basal circulation rate places a greater demand for oxygen to support it, which triggers in increase in red blood cell population so there is more hemoglobin to deliver O2. With more RBCs the circulation rate once more slows to the old basal rate.
