Answer:
B) It is present where connective tissue contacts the tissue it supports
Explanation:
Basal lamina is an extracellular matrix layer which is secreted by the epithelial cells on which the epithelium rests.The basal lamina is a scaffold anchoring epithelial cells, muscles, and nerve cells. Both basal cells in epithelia bind to the underlying basal lamina, which in turn is attached to the underlying connective tissue.

<h2>Cytoplasm</h2>
Cytoplasm is the inner content of the cell membrane which separates the cell membrane from the nucleus.
It is composed of cytosol, organelles and inclusions.
Cytosol is the soft, sticky and semi-transparent fluid in which various cell organelles are suspended.
Cytoplasm is not a simple clear fluid.
Rather, it is a complex viscous fluid that contains 70% water.
The remaining portion is made up of proteins, carbohydrates and lipids.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
The answer is the option "c"
The eruptions are caused by an accumulation of gases that press under a volcano.
The molten rock continues to generate upward pressure but can not advanced; this causes that its force increases with the passage of time, since it continues accumulating hot gases trying to come to the surface.
Finally, the surface yields and a volcanic eruption occurs.
