Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
The answer is (B) Edward's Syndrome, Down Syndrome, Klinefelter's Syndrome.
These syndromes are caused when there is an extra copy of chromosomes present in the cells.
In Edward's syndrome, there is an extra copy of the chromosome 18.
In Down's syndrome, there is an extra copy of chromosome 21.
In Klinefelter's syndrome, there is an extra copy of X chromosome.

Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a <u>dihybrid for two unlinked traits</u>.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
<em>Hence, the correct option is</em><em> C</em><em>.</em>
