Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
Answer:
microscope's condenser
Explanation:
The microscope's condenser is a substage lens that concentrates light on the specimen.
<em>The condenser of a microscope is a structure that helps concentrate light rays from the light source to illuminate the specimen on the stage of the microscope. It is made up of a system of lens that converges the ray of light and an aperture diaphragm that can be used to control the amount of light that gets to the specimen on the stage of the microscope.</em>
The names of the respiratory structures involved include the following: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli.
<h3>What is respiration?</h3>
Respiration is defined as the oxygenation of blood through the intake of oxygen and the removal of carbon dioxide.
The pathway of oxygen gas molecule from the surrounding air through the respiratory system to the blood include respectively the following:
- Nasal cavities (or oral cavity): This has a direct association with the outside oxygen from the environment.
- pharynx: This so also called the throat.
- trachea: This is also called the wind pipe.
- Primary bronchi (right & left): This divides from the trachea to form two bronchi.

I believe It is A because fissure eruptions are common on large volcanoes and also is built up by many layers of hardened lava, tephra, pumice, and volcanic ash.
It would be c :) hope that helps!
