The correct answer is - marine animals, amphibians, and reptilians.
The fossils of the animals can be very good indicator of what the climate has been in a particular period of the geological past. Some animals tend to thrive in warmer climates, some animals in colder climates, while some are typical for more moderate ones.
If the climate has been warmer, than it means that the sea levels would have been higher, thus larger water environment. That will result in an abundance of fossils of marine life. Also, the amphibians are enjoying the waters, thus they will be represented int he fossil records much more. The reptilians are a group of animals that are cold blooded, so whenever the climate is warmer they tend to thrive. Also, they diversify a lot in those periods and are becoming larger, thus the reptilian fossils will be abundant as well.
It can be said that fossil fuels contain stored solar energy because of age. <span>Since it has been around for millions of years, it contains some solar energy from millions of years</span>
Answer:
Option 1
Explanation:
The complete question is
Genetic variation can aid in the survival of species when the environment changes. Which of the following is the best example of an organism with a genetic variation that could improve survival chances over time?
- an ant that is resistance to pesticide
- a wasp that is infected with parasites
- a cactus that has no spines
- a mouse that has learned to avoid mousetraps
Solution
The survival chances of ants would be highest among all the species mentioned because it has developed a permanent resistance towards the pesticides used for killing insects. However, a mouse that has learned to avoid mousetrap will also have higher chances of survival but learning something cannot be counted as a genetic change.
Cactus without spines is a genetic change but it will not help in survival in fact it will have a negative impact on survival rate of cactus.
Hence, option 1 is correct
Deep ocean floor would be your answer :)
Water is able to dissolve many substances. that should be a perfect answer for you.
