Answer:
C. II and IV only
Explanation:
X linked recessive inheritance follows the criss-cross pattern in which affected mothers always have affected sons as sons get their X chromosome from mothers only. Condition "II" can not be true for X linked inheritance as hemophiliac mothers (XhXh) should have hemophiliac sons (XhY) only.
Daughters get one copy of their X chromosome from the father and the other from mother. To have affected daughters, mother should be carrier or hemophiliac and the father should be hemophiliac (XhY). This would make it possible for both the parent to transmit one copy of X chromosome with the gene to daughters (XhXh).

Answer:
Catalase
Explanation:
Catalase test is used to detect the presence of enzyme catalase.
Catalase is an enzyme that is formed by microorganism that lives in oxygen saturated environments so that there will be the break down of any toxic that comes with oxygen and hydrogen peroxide. This enzymes helps to differentiate catalase producing enzymes like staphylococci from bacteria that produce non-catalase like streptococci
Answer: E
<span>Neurons are cells
that facilitate communication from one part of the body to another and signals
are send as mean of communication which can be achieved through electrical
potentials. Thus, cell membrane around the neuron usually create ionic potentials
by separating various ions across tis cell membrane. However, the place where
most processes that involved in neuronal preservation and functioning are
triggered is known as neuronal membrane.</span>
