<span>Scientific method is a systematic procedure of making observations and for investigating phenomena. Scientific method is made up of the following steps; observe and state the problem, create your hypothesis, test your hypothesis or carry out experiment, analysis and record your data and then form a conclusion. Other scientists should be able to replicate your experiment anywhere in the world.</span><span />

This question is incomplete; the complete part is:
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.
Answer:
D (3/4)
Explanation:
This cross involves a single gene coding for flower colour in pea plant where the purple allele (P) is dominant over the white allele (p) since the purple allele masks the expression of the white allele in a heterozygous state (Pp). A cross between two heterozygous plants (Pp) will produce four possible offsprings with genotypes PP, Pp and pp in the ratio 1:2:1.
The PP and Pp genotypes are purple flowered while the pp is white flowered. Hence, the probability of having purple flowered plants from this cross is 3 out of 4 i.e. 3/4.
