Answer: The main way the thermal energy is transferred from the rock to the lizard is by conduction.
The lizard stretches out and warms itself by lying on a warm rock. The rock becomes warm as the sun transfers its thermal energy by radiation to the rock. The thermal energy to the lizard by the rock is transferred by direct contact through conduction. The air above the rock and the lizard also gets heated up and the heat is transferred through convection.
The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum, and smooth endoplasmic reticulum. It usally has ribosomes attatched to it.
The spiral usually begins with an increase in demand. The direct effect of this increase is that the producers (of commodities) raise prices to continue to make a profit. It usually begins with a rise in production costs.

The right answer is B.
Insulin is a hormone naturally secreted by the pancreas, specifically by specialized cells located in the islets of Langerhans. It allows glucose (sugar) to pass blood into the cells of the body. These will use glucose as energy or store it for future use.
In healthy subjects, insulin is secreted continuously. The body produces insulin according to the needs and foods consumed. For example, after a meal, the pancreas secretes additional insulin, allowing blood glucose to stay within normal limits.
