Answer:
The marine clamworm, Nereis, is carnivorous therefore its digestive system differs from that of the herbivorous earthworm, Lumbricus. The mouth and jaws are retractable (Figure 8, 9). If the jaws are retracted, cut along the midline of the pharynx and pull the jaws out with a pair of forceps.

Starch is a polymer composed of glucose units as monomers. Hydrolysis reaction can break down large molecules into smaller ones.
- Hydrolysis is a type of chemical reaction in which a water (H2O) molecule is used to break down large molecules into smaller ones.
- Starch is a complex polysaccharide composed of more than six (6) glucose molecules linked by alpha-glycosidic bonds.
- Glycosidic bonds can be hydrolyzed by specific enzymes known as glycosidases.
- A starch molecule composed of 300 glucose molecules contains 299 alpha-glycosidic bonds.
- In consequence, in this case, 299 water (H2O) molecules are required to completely hydrolyze the amylose starch polymer into glucose monomers.

Answer:
c) 330
Explanation:
Formula to calculate exponential growth is written as:
y = a( 1+r)ⁿ
a = initial quantity
r = growth rate as a decimal
n = number of time intervals
y = quantity after n time
As per the question given
a = 300
r = 0.1
n = 1 year
y = ?
Thus,
y = a( 1+r)ⁿ
300(1+0.1)¹
300 × 1.1 = 330
Therefore,
y = 330
