the answer is the cell membrane
Correct option C) Hydrophilic portions of the lipids are in the interior of the membrane.
Lipids and proteins free to move laterally in membranes because both are inserted into a fluid lipid bi-layer and they are able to diffuse laterally through the membrane.
Lipid Composition of Cell Membranes is a important property of lipid bilayers which is behave as two-dimensional fluids where individual molecules are rotate and move freely in lateral directions
Membrane proteins and phospholipids both are unable to move back and forth between the inner and outer leaflets of the membrane at an appreciable rate. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or undergo transverse movement between bilayers.

In this case, the unconditioned stimulus is; Chemotherapy.
Cancer are group of diseases caused by rapid growth of abnormal cells in the body. Chemotherapy is a treatment that involves the use of medications (anti-cancer drugs) to treat cancer.

<u>ANSWER:</u>
The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.
<u>EXPLANATION:</u>
- Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour.
- This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.
