Asteroids vary greatly in size and are mostly made up of frozen water and gas. This one is true.
They are said to be "mostly formed of ice and gas" as they rarely can be found consisting of stone, nickel and iron. These are extremely dangerous in our Universe.
From this one migrant species would come many -- at least 13 species of finch evolving from the single ancestor.
This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. The ecological niches exert the selection pressures that push the populations in various directions. On various islands, finch species have become adapted for different diets: seeds, insects, flowers, the blood of seabirds, and leaves.
The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters.
Scientists long after Darwin spent years trying to understand the process that had created so many types of finches that differed mainly in the size and shape of their beaks.
<span>The Left-sided Problem of the heart involves the lack of enough supply of oxygen induced blood and the blood which is unable to reach the heart goes to lungs causing breath issues. Another issue with this problem is that left side of the heart pumps blood into the body, so when it fails, less blood will be pumped into the arteries.</span>
Answer:
when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.
Explanation:
Hope this helped Mark BRAINLEST!!!
The results of the study would be expected to change if the same experiment were repeated with natural gas in the area of a decrease in the reaction time.
<h3>What is Reaction time?</h3>
This is the time frame between when a stimulus and a response or total time taken for a reaction to occur.
Natural gas produces steady amount of heat with a higher temperature which leads to a decrease in reaction time.
