Answer:
what should i answer lets say D
Answer:
<em><u>The correct option is D) The two species have a common ancestor</u></em>
Explanation:
In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.
Answer: here´s why
Explanation: Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice.

Atropine would block the receptor called muscarinic acetylcholine receptors present in the eye.
Atropine is the Anticholinergic agent which is also known as parasympatholytics. The activity of neurotransmitters at the receptors leads to pupil constriction.
Atropine is used to block these receptors that allow the pupillary muscles to relax. This causes the dilation of the pupil.
Atropine is the mydriatics that is used for pupillary dilation to conduct a detailed examination of eye diseases.
without this medication, the pupil will only dilate in the darkness. However, doctors cannot examine the eye problems as there is darkness as they need light for checkups.
