Answer:
pupils
Explanation:
When we step out into bright light, the pupil will contract, reducing the amount of light entering into the eye and protecting our retinas, as well as allowing us to see more clearly. The reason we blink and screw our eyes up in this situation is that this change in pupil size isn't instantaneous.
Answer:
Your pupils
Explanation:
When you all of the sudden go into a bright light, your pupils become smaller to adjust to the brightness. When you go back to a less dark space, your pupils will enlarge.

Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.
The correct answer is:
Option C. Similar fossils are found on the coasts of South America and Africa.
The explanation for the correct answer is:
Therefore, alike fossils found in various continents supports the theory of continental drift.
To learn more about continental drift follow the given link:

B. Metaphase II
C. Mitosis
D. Prophase I
The correct answer is option D. Prophase I
The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.
-the least informative property of a mineral
-measured using the Mohs scale
-the way a mineral splits when stressed
Answer: measured using the Mohs scale
Explanation:
Hardness is defined as ability of the surface to undergo resist deformation.
The degree of hardness is determined by observing the comparative ease or difficulty which which one mineral is scratched by another.
Color is the least informative property of a mineral.
Mohs scale of hardness gives a rating of 1 to talc which is categorized as most soft and rating of 10 to diamond which is categorized as most hard.
Hardness is the physical property of mineral measured using the Mohs scale. Hardness is property of mineral to resist scratch. On Mohs scale minerals are classified according to their hardness. Hardest mineral on the scale is Diamond. While the softest mineral is Talc. Different test are done to test the hardness of minerals. These includes, test of scratch from finger nail, test of scratch from knife/blade and test of mineral by a piece of glass. On Mohs scale minerals are classified according to their hardness:
10. Diamond
9. Corundum
8. Topaz
7. Quartz
6. Orthoclase
5. Apatite
4. Fluorite
3. Calcite
2. Gypsum
1. Talc
