why can AIDS be classified as both an infectious disease and an immune system disorder ?

Answer:

Because AIDS can not only be passed from person to person but it can also affect your immune system in ways other infections diseases can not.

Explanation:

for example: type 1 diabetes is an auto-immune disorder and can not be passed on by bodily fluids. chlamydia is an infectious disease that can be passed on by bodily fluids.

AIDS is an auto immune disorder because it affects the immune system in the same ways that other auto-immune disorders do. this being so it can all so be found in the blood and passed on like an infection where as auto-immune disorders normally dont live in a persons blood.

sorry if this is confusing. hope this helps

Read the passage from Darwin's journal. sorry its so long


The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.




What structural adaptation does the A. cristatus lizard have to help them climb rocks?

Awnsers:

A.strong claws

B.black color


C.flattened tail


D.webbed feet
