Answer:
Rocks across the ocean floor have alternating magnetic stripes.
Explanation:
Different types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence made scientists take a second look at Wegener's hypothesis of continental drift.
Answer:
Temperature and precipitation.
Explanation:
Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.
Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

Answer:
Since all cells in our body contain DNA, there are lots of places for mutation to occur; however, some mutations cannot be passed on to the offspring and do not matter for evolution.

Answer:
Lab results: The oil will stain red with Sudan III dye since it is a lipid and contains triglycerides. However, since the oil is less dense than water and insoluble in water, the oil will form a layer or globules above the water and appear as a red layer above the water in the test tube
