Answer: ,Option B.

The Earth's axis has a 23.5 degree tilt.

Explanation:

The Earth axis of rotation is tilted to 23.5 degrees which is relatively to the orbital plane, this lead to differences in seasons of the places on Earth at a particular time. The angles varies overtime but moon gravitational pull prevent it from shifting more than a degree. There is different in seasons in the northern and southern hemisphere because at a time one part of it exposed to the Ray's of sunlight than the other which lead how the Earth's revolve round it's axis.

A phagocytic cell has a mutation in a gene for a hydrolytic enzyme that renders the enzyme nonfunctional. What is the most likel
pshichka [43]

Answer: The phagocyte’s ability to destroy the ingested pathogen is compromised and it will become inactive.

Explanation:

There are different hydrolytic enzymes. Lysozyme attacks cell walls of gram positive bacteria. Elastase is a protease. Collagenase attacks collagen, produced by some bacteria. Plasminogen activator is also a protease.

Loss of function of any one of these enzymes will reduce or prevent the breakdown of bacteria in the phagosome (vacuole) so that the phagocyte is inactivated.
