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.
Answer:
Mass extinctions, Wegenerian cycles, and the emergence of new life forms
Explanation:
Answer:
a. Anabolic pathways build molecules, require energy, and are endergonic.
Explanation:
<em>Anabolic pathway </em>describes the metabolic reactions that<em> </em><em>build up</em><em> complex molecules from simpler ones</em>, typically via condensation (monomers covalently joined producing water as a by-product).<em> It </em><em>requires energy </em><em>to construct new bonds, this means is </em><em>endergonic</em><em>.</em>
The catabolic pathway, on the other hand, describes metabolic reactions that<em> </em><em>break complex molecules down </em><em>into simple ones</em>, typically via hydrolysis (consumption of water to break bonds within the polymer). <em>It </em><em>releases energy </em><em>when these bonds are broken, this means it is </em><em>exergonic</em><em>.</em>
Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.

Answer:
The diameter of the xylem vessels should be small in order for the capillary action to take place.
Explanation:
The vessels through which water is transported to different parts of the plants and trees are the xylem. Water is transported in the trees through a mechanism named as capillary action. This mechanism can occur only if the diameter of the vessels are small.
The water molecules adhere to the walls of xylem and an upward force is generated. If the diameter of the vessels i.e xylem would be small then the surface tension between the xylem and water molecules would be enough to move the water in an upward direction.
Answer:
C.) greater
Explanation:
Since the rock now physically has less total volume, the rate of it weathering is proportional to the size and the force pressed upon the rock.
