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.
Answer:
Pond
Explanation:
Ponds are inland water bodies that are usually smaller in surface area than a lake and nonflowing in contrast to rivers or streams. However, a pond is a shallow freshwater source that inhabits organisms' life (plants and animals alike).
Due to the shallow state of a pond, light penetrates to the bottom, hence, allowing the constant growth of plant life. Therefore, PONDS are freshwater sources that contains a permanent shallow body of water with plant life throughout.

The earth's tilt of 23.5 degrees to it's axis as it revolves around the sun causes seasons; summer, spring, winter and autumn. This is due to the orientation of the earth with respect to the sun that cause variations in how to sun rays 'strike' the earth. Consequently, there are variations in temperatures across the earth, over its complete revolution, causing seasons my brotha, Hope this helps!
