Answer:
The correct answer will be option-D
Explanation:
The evolution of vascular tissues in plants from non-vascular plants was an adaptive feature to survive in the terrestrial environment. The group of plants in which vascular tissues evolved and developed is the Pteridophytes which contained stellar organization of the vascular bundles.
The pteridophytes exhibited xylem and phloem which allows the rapid uptake of the water and nutrients from the soil which allowed the growth of the plant and since plants got enough water and nutrients from the soil, they adapted to grow tall so that they can maximize the output of photosynthesis in bright sunshine.
Thus, option-D is the correct answer.

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: Aminos, Phosphates and Carbonyls

Which of the following best explains the reactions of these enzymes?
A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.
B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.
C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.
D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.
The answer is A
Explanation:
In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.
Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).
On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.
