The answer to your question is B.
When light traveling in a vacuum enters a new transparent medium, such as air, water, or glass, the speed is reduced in proportion to the refractive index of the new material. As the slider is translated to the right, the refractive index increases and the speed of light subsequently decreases.
<span>Photosynthesis replenishes the earth’s atmosphere with oxygen. The two variables that affect the rate of photosynthesis are (1) the production of oxygen (O2) and, (2) consumption of carbon dioxide (CO2). The buoyancy of the leaf is an indirect measurement of the net rate of photosynthesis in the leaf tissue. The more oxygen the leaf contains, the more buoyant or the more it floats in the water.</span>
The answer to this question would be choice C. the existence of homologous structures
---------------------------------------------------------------------------------------------------------Explanation: Basically, homologous structures are structures that are similar to each other, but are found in different organisms (or animals). In other words, they are structures in common between species. Moreover, this homologous structures basically show that organisms come from a common ancestor and have changed over time.
