Two questions have been asked, and responded to
Answer:
For question 1: The statement is true
For question 2: Yes, the two wild roses are of the same population
Explanation:
Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.
I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.
2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because
- it is still a given area or habitat
- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.
Answer:
B, A fossil found in rocks from one time period
Explanation:
Fossils are used to determine the ages of rock layers. Index fossils are the most useful for this. Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in. Hope that this helps you :)
