2.

Thus , there are 56 outcomes possible for this experiment
D is the answer hopw this helps
<span>A spider is small enough that its weight can be supported by surface tension, the relatively weak forces that hold water molecules together. </span>Water molecules "bond"<span> to other water molecules around them in all directions, so they tend to stick more strongly to their neighbors, forming a film-like layer across the surface</span>
Answer:
Estrogen.
Explanation:
Plasma membrane is made of lipids and proteins. The lipids are arranged in bilayers and proteins are embedded or may span the lipid bilayer. The carbohydrates are attached on the surface of the membrane.
The molecules that are lipophillic in nature can easily diffuse through the plasma membrane. Among the molecules listed in the question, estrogen is highly lipophillic in nature and can easily cross the lipid bilayer of the plasma membrane.
Thus, the correct answer is option (d).
