The lab allowed me to model and observe stream and river processes. Using a virtual model, I compared low and high velocity streams or rivers, low and high gradient streams or rivers, and low and high volume streams or rivers. I found that higher velocity streams or rivers can cause more erosion, as do higher gradient and higher volume streams or rivers. Not only did these factors move more small sediment, they also moved larger pieces of sediment.

Some species of penguins, such as chinstrap penguins, depend on open water for their survival. Other species of penguins, such as Adélie penguins, depend on ice. Over the last 20 years, the population size of chinstrap penguins has increased, and the population size of Adélie penguins has decreased. An increase in global air and water temperatures likely caused <span>these changes in population size.</span>

Animals with a three-chambered heart would include:_______

Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.

Irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

<h3>What is irrigation?</h3>

Irrigation is a technology based on the artificial supply of water to recover crops from drought conditions.

Genetic modification may also help with drought conditions by inserting into the genome of the target species gene sequences associated with hydric stress (e.g., a protein channel to close stomata at night).

In conclusion, irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.
