Answer:
<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
- To find velocity of a object we need 3 factors
- Magnitude
- speed
- Distance
- Hence Here both option A and C are correct
It would be impossible to feel them move because they are moving to slow for us to realize it. Well, that is what I think.
Volume of milk that a glass can hold = 230 cubic cm
It is already given that
1 gallon of milk = 3.79 liters
W already know
1 liter = 1000 cubic cm
Then
3.79 liters = 1000 * 3.79 cubic cm
= 3790 cubic cm
Now
Number of glasses needed to contain 230 cm^3 of milk = 1
So
<span>Number of glasses needed to contain 3790 cm^3 of milk = 3790/230
</span> = 16.48
From the above deduction, we can conclude that 17 glasses of milk are required to hold 1 gallon of milk.
The size of the algal size will increase or swell when a student removes an algal cell from its marine environment and puts it into a sample of freshwater.
Tonicity refers to the concentration of a solution compared to another solution. A solution is said to be hypertonic, if it has a greater concentration of solutes than the other solution. A solution is said to be hypotonic, if it has a lower concentration of solutes than the other solution. A solution is said to be isotonic, if it has the same concentration of solutes as of the other solution.
In a marine environment, the algal cells are said to be hypertonic with a higher concentration of the solutes than the freshwater. When such a cell is placed in freshwater with hypotonic environment, the concentration of solutes in the cell is higher than the external environment. In other words, it has lesser water molecules in it. As a result, osmosis occurs which is the movement of water molecules from a region of its higher concentration to a region of its lower concentration through a semipermeable membrane and water enters the cell from the freshwater. Thus, increasing the size of the algal cell or the algal cell swells.
Answer:
The correct answer is option c. "a set of reactions that release energy that can be used to drive cellular work".
Explanation:
Catabolism is a part of metabolism at which molecules are broken down into smaller units in order to release energy that could be used in other reactions that drive cellular work. A catabolic pathway follows catabolism criteria. Catabolic pathways are the opposite of anabolic pathways, at which large molecules are synthesized with the requirement of external energy supply.
