Answer;
Responsiveness
Excretion
Explanation;
Excess carbon dioxide must be removed from the body to stop it reaching toxic levels. As the blood flows through the lungs, excess carbon dioxide passes out of the blood and into the alveoli by diffusion. It is then removed from the lungs when we exhale (breathe out).
-Carbon dioxide helps remove carbon dioxide (a waste gas that can be toxic) from your body. The lungs' intake of oxygen and removal of carbon dioxide is called gas exchange. Gas exchange is part of breathing.

Complete Question:
Students investigated samples of amylase from 100 goats. 100 small filter paper discs were each soaked in a different sample of goat amylase. The students tested the activity of these amlyase samples using plain paper. Plain paper contains starch.
A circle of plain paper was placed into a Petri dish ad shown in the diagram below. Iodine solution was used to stain the starch in the plain paper.
When iodine solution reacts with the starch in the plain paper, what colour would you see?
Answer:
The colour that would be seen is blue black .
Explanation:
Amylase is an enzyme that is involved in the breaking down or hydrolyses of starch.
When Amylase reacts with iodine, it speeds up the rate of reaction of the hydrolysis of the starch present in the plain paper.
The colour that would be observed is a blue black colour and the starch in the paper would be broken down further more into simpler sugars.

But the youngest layer at the top was deposited by a river. This shows the geologist that the local environment changed suddenly from an ocean setting to a river system.
