Answer:
The correct answer is option A
A. A marine body fish
Explanation: this is because they need to retain water. The piscine kidney cannot afford to produce a urine of higher concentration than the fluids in the body so production is kept at minimum.
• there a 6 muscles (extralocular muscles) that control the movement of the human eye but a cow only has 4. therefore, they can look up, down, left and right but they cannot move their eyes in certain ways that humans can, such as rolling their eyes; humans are able to move their eyes in more directions.
It probably needs to dig in the ground for worms and grub. So it's an adaptation for finding food.
The answer choices to this question are:
<span>a.
</span>Learned
helplessness.
<span>b.
</span>Stimulus
discrimination.
<span>c.
</span>Aversive
conditioning.
<span>d.
</span>Vicarious
learning.
The best answer choice is:
<span>a. </span>Learned
helplessness
<span>Explanation: Learned helplessness was studied by
Seligman as a potential animal model of depression. Learned
helplessness occurs when people or animals feel helpless to
avoid negative situations. Martin Seligman first observed learned
helplessness when he was doing experiments on dogs. He noticed that the dogs
didn't try to escape the shocks if they had been conditioned to believe that
they couldn't escape.</span>
<h2>Answer is option "C"</h2>
Explanation:
- The way that these formative highlights are so like the gill structures in fish bolsters that fish, chicks, and people share a typical predecessor
- Ancestral characters are regularly, however not constantly, safeguarded in a life form's improvement. For example, both chick and human early creatures experience a stage where they have cuts and bends in their necks like the gill cuts and gill bends of fish
- These structures are not gills and don't shape into gills in chicks and individuals, be that as it may, how they are so similar to gill structures in fish currently being created support that chicks and individuals share a run of the mill ancestor with fish. Subsequently, formative characters, alongside different lines of proof, can be utilized for developing phylogenies
- Hence, the right answer is option C "fish, birds, and humans share a common ancestor"
