Answer:
Reusing
Explanation:
Reusing is the process of using the same thing, resource, again and again, sometimes for the same purpose and sometimes for the new one. This reuse can have many economical and ecological benefits.
There are many ways to reuse and start this process of ecological thinking:
- in the shopping, reusable bags can be used instead of the plastic ones
- Reuse of the water-the water already used for washing can be used for watering the plants
- Use the benefits of the rain
Answer:
B. In the small intestine, carboxypeptidase attacks peptide bonds.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.
Explanation:
The digestion of protiens doesn't occur in mouth, it occurs at only 2 locations in GIT :
- In the stomach
- In the small intestine
Digestion of protiens start in stomach causing the stimulation of gatrin hormoone which stimulates the release of gastric juice containing HCl , Pepsinogen , Rennin (in infants). The pepsinogen is activated to pepsin by HCL and pepsin itslef, and cause hydrolysis of the peptide bonds in the protiens.
The remainder of protien digestion occurs in small intestine as a result of the action of enzymes including trypsin and peptidases. Carboxypeptidases attack the peptide bonds and result in cleavage.
Answer:
B. the direction of the wind at the time it was deposited
Explanation:
Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
Answer:
a. Independent Variable: different sized aquariums
b. Dependent Variable: number of surviving fish
c. Controlled Variables/Constants: amount and type of food, aquarium maintenance and water temperature
d. Experimental Controls/Control Groups: none
Explanation:
In an experiment, the dependent variable is the condition that is being measured or tested in the experimental procedure, while the independent variable isn't changed and serves to measure the outcome of the dependent variable. Moreover, the constant variables are those conditions that stay the same in the experiment. As observed in the case above described, an experiment usually has multiple constant variables. Finally, a control group is composed of individuals/research subjects who do not receive the experimental treatment, and therefore they can be used to compare the outcomes observed in the experimental groups.
