Josephine and Enrico both measured the width of a table using their hands. Josephine determined that the width of the table was six hands. Enrico determined that it was five hands. Both of these are valid measurements, but neither is accurate. If they would like to use their hands, how can they best determine the actual width of the table?
-
Use only one of their hands
-
Measure each student's hand with a ruler
-
Use only the fingers on their hands
-
Measure both students' hands with a ruler and use the total
Correct Answer
A. Measure both students' hands with a ruler and use the totalExplanation
To determine the actual width of the table using their hands, Josephine and Enrico should measure both of their hands with a ruler and use the total. This method takes into account the fact that each person's hand size may vary, and by measuring both hands of each person and adding the measurements together, they can get a more accurate estimation of the table's width. This approach eliminates the potential inaccuracies of using only one hand or only the fingers on their hands.Rate this question:

Variation between members of a species plays an important role in Darwin’s theory of natural selection. What happens to variation in endangered species where the number of individuals is very low?
-
They become extinct
-
They evolve into a species that can survive
-
Few variations occur
-
Their variations lead to adaptations
Correct Answer
A. Few variations occurExplanation
In endangered species with a very low number of individuals, there is a reduced gene pool and limited genetic diversity. This lack of genetic variation makes it difficult for new variations to arise through mutations or recombination. As a result, few variations occur within the population. This can be detrimental to the species' ability to adapt to changing environments and increases their vulnerability to extinction.Rate this question:

Two different fossils found in the same layer of sedimentary rock are most likely
-
Fossils of the same species.
-
Fossils that formed in lava that cooled.
-
The remains of organisms that have the same relative age.
-
The remains of organisms that lived in different climates.
Correct Answer
A. The remains of organisms that have the same relative age.Explanation
Two different fossils found in the same layer of sedimentary rock are most likely the remains of organisms that have the same relative age. Sedimentary rocks are formed by the accumulation of sediments over time, with each layer representing a different time period. Fossils found in the same layer would have been deposited at the same time, indicating that they are of similar age. This suggests that the organisms from which the fossils originated lived around the same time and are therefore likely to have the same relative age.Rate this question:

A dig in a desert finds a large number of fossils of marine (sea) plants and animals thought to be more than 200 million years old. What is the MOST LIKELY explanation for this finding?
-
The area was once covered by an ocean.
-
The area was a dumping ground for humans that ate sea creatures.
-
The area used to receive large amounts of rainfall.
-
The area was once covered by a glacier.
Correct Answer
A. The area was once covered by an ocean.Explanation
The presence of marine fossils in a desert suggests that the area was once covered by an ocean. Fossils are the remains or traces of ancient organisms, and the fact that these fossils are of marine plants and animals indicates that there was once a body of water in the area. Over millions of years, geological processes such as tectonic movements or changes in sea level could have caused the ocean to recede, leaving behind the fossils in what is now a desert. The other options, such as human activity or glacial coverage, are less likely explanations as they do not align with the evidence of marine fossils.Rate this question:
