Choice #1 & Choice#4 I believe
The correct answer is going to be <span>C. It is the continuous movement of water under, on or above the Earth's surface</span>
C. It requires active transport because the use of energy is necessary, the natural and opposite flow to this, would be from high to low concentration that requires little to no energy (i.e passive diffusion).
Answer:
The correct matches are given as follows:
a. Amylase
- Starch
b. Pepsin
- Protein
c. Lipase- fats
Explanation:
The digestion can be defined as the breaking down of the complex compounds of food into simpler compounds for their better absorption. There are various enzyme that help in the process of digestion. Amylase, pepsin, and lipase are enzymes. The amylase is an enzyme responsible for breakdown of starch. The pepsin is responsible for the breakdown of protein into amino acids. The lipase is responsible for breakdown of fats.
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
