Hi! What are the possible answers?
Compound microscope is commonly used in the schools and colleges. It has two lenses, the objective lens and the ocular lens. It provides a magnification of 1500X. Eyepiece lens is of 10X or 15X power. It is used to observe bacterial, protozoa, various cells, etc.
Dissecting Microscope It is also called stereo microscope. Its magnification power is less than the other microscope. It gives a 3 dimensional picture. Due to the low magnifying power they are used to observe little bigger objects than other microscopes. They are used in the surgeries, dissection, forensic science etc.
Answer: all of them apply to Darwin's concepts.
The following concepts related to evolution are:
Letter A
Letter B
Letter C
Letter D
Letter E
Explanation:
<em>1. Darwin defined evolution as descent with modification meaning that species change over time, give rise to new species and share a common ancestor. (letter A)</em>
<em>2. Since the natural selection is mechanism proposed bay Darwin for evolution, based on the fact that resources are limited in nature, organism with heritable traits that favor survival and reproduction tend to leave more offspring than their peers, causing to increase in frequency over generations. (Letter C and E)</em>
<em>3. Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. It depends on the environment and requires existing heritable variation in a group. ( Letter D)</em>
<em>4. Natural selection can be considered a mechanism of change since the suviving group will determine the caracteristics of the next generation. Moreover after several generations of selection, the population might be made up entirely different, according to the environment, the inheritage and improvement of the specie. ( Letter B)</em>
