Answer:
b. 80
Explanation:
There are about 4 calories per gram of carbohydrates. As such, if 20 grams of carbohydrate are provided, simply multiply 4 calories per gram with the total amount of grams of carbohydrates.
<em>20 grams of carbohydrates</em> x <em>4 calories per gram of carbohydrates</em> = 80 calories total.

Answer:
Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

Answer:
Yes, it accelerates
Explanation:
We have that:
The ball was stationary implies that its initial velocity, u = 0
It gained 5m/s means that its final velocity, v = 5m/s
Using first law of newton, we can determine whether it accelerates or not.
Substitute values for v and u
Make a the subject
<em>This implies that the ball accelerates over a period of time t</em>
<em></em>
Another way to tell if it accelerates or not is to consider the change in velocity.
When there is an increment in velocity of an object, the object accelerates.
In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
