In a mass extinction, many species become extinct at the same time. scientists have concluded that a mass extinction killed the dinosaurs and other species, in part as a result of an asteroid striking the planet. what pattern in the fossil record supports this conclusion?
The pattern in the fossil record which supports the idea of a mass extinction event is the sharp decrease in biodiversity in rock layers.
What is a mass extinction event?A mass extinction event is one which in which a large number of species of organisms die off due to natural or artificial causes.
A mass extinction events is concluded to have killed the dinosaurs and other species, in part as a result of an asteroid striking the planet.
The evidence for this in fossils records is that the lower, older rock layers contains a great diversity of fossil life forms, while the younger layer immediately above is contains few organisms in comparison.
Therefore, the sharp decrease in biodiversity in rock layers provides evidence for a mass extinction event.

Animals from colder climates generally have shorter limbs. This is called
(a) Allen’s rule
(b) Johnson’s rule
(c) Arber’s rule
(d) Niche rule
Answer:
(a) Allen's rule
Explanation:
It is a heat-conservation mechanism that prevents heat loss from the body. Heat gain and heat loss can be maximised and minimised by lowering the surface area to volume ratio of the body. Small animals are uncommon in the polar regions due to their larger surface area and lower volume.

According to the Frank-Starling Law of the heart, as contraction strength increases the stroke volume ________. Group of answer choices decreases shows no change increases
We can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.
What is the Frank-Starling Law of the heart?This law indicates the relationship between the volume of the ventricle, specifically the left ventricle, and the strength of its contractions. It follows the logical approach that if there is more volume in the ventricle, the cardiac muscles will have to stretch to allow for the space, which in turn causes a much stronger contraction when these muscles activate.
Therefore, we can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.
