Question 1
Question
Diffusion is the [blank_start]spreading out[blank_end] of particles [blank_start]resulting in[blank_end] the [blank_start]net[blank_end] movement from a region of [blank_start]high[blank_end] concentration to a region of [blank_start]low[blank_end] concentration. The greater the [blank_start]concentration gradient[blank_end], the [blank_start]faster[blank_end] the rate of diffusion.
Answer
-
spreading out
-
resulting in
-
net
-
high
-
low
-
concentration gradient
-
faster
Question 2
Question
1) [blank_start]Muscular[blank_end] tissue, which can contract to bring about [blank_start]movement[blank_end].
2) Glandular tissue, which can produce [blank_start]substances[blank_end] such as [blank_start]enzymes[blank_end].
3) [blank_start]Epithelial[blank_end] tissue, which [blank_start]covers[blank_end] [blank_start]part[blank_end] of the [blank_start]body[blank_end].
Answer
-
Muscular
-
movement
-
substances
-
enzymes
-
Epithelial
-
covers
-
part
-
body
Question 3
Question
Muscular tissue [blank_start]churns the contents[blank_end] in the stomach.
Glandular tissue produces [blank_start]enzymes/ digestive juices[blank_end].
Epithelial tissue [blank_start]covers[blank_end] the inside of the stomach.
Question 4
Question
Glands ([blank_start]pancreas[blank_end]) produces [blank_start]digestive juices[blank_end].
[blank_start]Stomach and the small intestine[blank_end] is where digestion occurs.
The [blank_start]liver[blank_end] produces bile, which neutralises the acid in [blank_start]food from the stomach[blank_end] and [blank_start]emulsifies fats[blank_end], making them smaller and thus having a [blank_start]greater[blank_end] surface area.
[blank_start]Absorption of soluble food[blank_end] happens in the small intestine.
[blank_start]Water is absorbed[blank_end] in the large intestine.
Question 5
Question
Protease enzymes in the stomach work best in [blank_start]acidic[blank_end] conditions. [blank_start]Glands[blank_end] in the stomach wall produce [blank_start]hydrochloric acid[blank_end] to create very [blank_start]acidic[blank_end] conditions.
Amylase and [blank_start]lipase[blank_end] work in the [blank_start]small intestine[blank_end]. They work best when the conditions are slightly [blank_start]alkaline[blank_end].
The bile produced by the [blank_start]liver[blank_end] is stored in the [blank_start]gall bladder[blank_end] and released into the [blank_start]small intestine[blank_end].

Question 9
Question
In industry, [blank_start]enzymes[blank_end] are used to bring about [blank_start]reactions[blank_end] at [blank_start]normal[blank_end] temperatures and [blank_start]pressures[blank_end] that would otherwise require [blank_start]expensive[blank_end], [blank_start]energy[blank_end]-demanding equipment. However, most enzymes are [blank_start]denatured[blank_end] at high [blank_start]temperatures[blank_end] and many are [blank_start]costly[blank_end] to produce
