O D. It produces digestive enzymes.

SUBMIT

Answer:

Option A

Explanation:

The endocrine system and the excretory system works hand in hand in maintained thé functions of the body and in this context that kidneys. The hypothalamus functions in monitoring the amount of electrolytes in the blood and an increase in this amount indicates dehydration among others, whose cause might be s a result of low water intake, too much sweat etc. Detecting this, the hypothalamus signals for the secretion of antidiuretic hormone which moves to the kidneys and stimulate the organ to reabsorb more water. This hormone is transferred to and released by the pituitary gland all these being part of the endocrine system.

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

A scientist decides to study the effect of salt on a particular type of bacteria. Arrange the steps of the scientific method in the correct order to
show how the scientist would proceed with his work.
The scientist asks the question,
Does salt help the growth of
these bacteria?
>
The scientist puts the bacteria in
three different environments:
high salt, medium salt, and low salt.
A microbiologist notices that
some bacterial species thrive
in salt water environments.
The scientist forms a hypothesis
that higher concentrations of salt
may increase the growth of these
types of bacteria.
The scientist publishes his report
in a scientific journal.
