Fatty acids and glycerol best describes the basic structure of lipids. Fatty acids is one of the major components of triglyceride. It is a form of lipids that is used to store energy. Fatty acids are composed largely of a chain carbon atoms bonded with hydrogen atoms. At one of the ends of fatty acids is called carboxyl group. In terms of number of carbons, they are typically an even numbers.
Answer:
Si existe variación en el acervo genético de la población, esto permite que la selección natural actúe sobre los rasgos de la población que permiten la adaptación al ambiente cambiante. Cuanta más diversidad hay en una población, mayor es la probabilidad de que la población pueda adaptarse a los nuevos cambios.
Explanation:
While looking at the figure, the union of the left and right brachiocephalic veins is Point A.
<h3>
What are brachiocephalic veins?</h3>
- The internal jugular vein and the subclavian vein join to form the brachiocephalic veins, also known as the innominate veins, which are substantial venous systems in the thorax.
- On the right side of the upper chest, the superior vena cava is formed by the union of the left and right brachiocephalic veins.
- These blood arteries are an essential part of the circulatory system in humans because they facilitate the removal of deoxygenated blood from the head and upper limbs.
- The internal jugular vein on the right and subclavian vein on the left combine to form the brachiocephalic veins. Both the vena cava and the brachiocephalic veins lack valves.

The two statements that describe the girls' experience are:
"Heat was transferred from the fire to the rock." and "<span>The girls used conduction to cook the bacon.".
The heat that the rocks had to cook the bacon was obtained when they were in the fire, the rocks accumulated heat and were then releasing it. Heat was transferred from the fire to the rocks. By cooking the bacon on the hot rocks, the heat accumulated in the stones was being transferred to the surrounding environment of the rocks and as the bacon was in direct contact with rocks, plus a heat conducting fluid was in between, that heat was passed to the bacon by conduction.
There was no convection currents to cook the bacon; the bacon and the fire were in no equilibrium as they were not even in contact; energy was transferred from the rocks to the bacon and not from the bacon to the rocks as the bacon got warmer.</span>
<em>Computer model is generally used to predict long-term events</em>
Answer: <em>C. Computer model
</em>
Explanation:
Scientific models are used to predict and elaborate the behaviour of the real objects in the field of physics, chemistry, ecology and earth science. Computer model is the type of scientific model that is used to explain long term events.
A computer model is used to follow patterns of the weather along with the factors to forecast natural events. It is not the only type of model to make predictions.
For instance, predicting earthquake uses computer model, relationship between time and distance is the idea model, study of cell and its various parts uses physical model.
