Answer:
Explanation:
The melting point is the temperature at which any substance melts i.e changes its state from solid to liquid.
Melting is a phase change from solid to liquid.
- Melting point is a temperature value or number.
- Melting is phase change from solid to liquid.
- Melting usually occurs when temperature is added to a body.
- The melting point of all pure samples of a compound is the same as it is an intensive property.
- Melting is physical change of matter.
The control group is the group that does not receive the experimental treatment. Experimenters use the control group to compare it to the experimental group in order to determine if the treatment had an effect. So, if there is the same result in both groups (decrease in the grass blades) it means that the given treatment had no effect on the experimental group and that the decrease is due to some other conditions.
Study of fossils has led to important new understanding about how life evolved on earth and about diseases, both ancient and modern. Fossils also help us understand past climates, including ice ages and periods that were warmer than our present climate. Knowledge from the study of fossils is helping geoscientists understand global warming and its effects. By studying the catastrophic extinction of the dinosaurs and many other life forms at the end of the Cretaceous Period, geoscientists have gained insight into the evolutionary implications of impacts by extraterrestrial objects. Investigating the physical and chemical characteristics of fossil organisms that lived during times of drastic climatic change helps us understand the implications of the changes we are making in our own environment. <span>Information about Earth history, practical help in finding energy resources, and information that helps us anticipate the effects of possible environmental changes are not the only benefits derived from fossils. hope this helps :)</span>
Answer:
Option C
Explanation:
Animals will migrate to other places because they have less food and shelter. Since the forest have been cleared, their habitat (where they lived) is no more and they have to move to another place in order to survive because there would be no more food for them here.
Answer:
C
Explanation:
You subtract 499-473. That shows how much water is displaced and the volume of the stone. Hope this helps and have a great day!
