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.

eaten all his chocolate chip cookies.
a. Reproduction
b. Response to stimuli
c. Growth and development
d. Obtaining resources for energy
Answer:
D I'm pretty sure
Explanation:
Consider the cross aa bb cc dd ee x aa bb cc dd ee. If these 5 allele pairs all assort independently, then the probability that any individual offspring will have the genotype aa bb cc dd ee is 1 out of.
If the allele pairs assort independently, the probability that any individual offspring will have the genotype aabbccddee would be 100% or 1 out of 1.
Independent assortmentSince the alleles assort independently, the gametes from each genotype will all be abcde.
Crossing abcde and abcde:
abcde x abcde
aabbccddee
This means that all the progeny from the cross will be aabbccddee giving a 100% chance.

How quickly does water flow through the soil? How quickly does water flow through the soil? Does the soil smell good or bad? Does the soil smell good or bad?
The question that can be answered using the sense of touch is : ( B ) is the soil grainy
Sense of touch
The graininess of the soil can be felt by the touch of the hands because it is a physical attribute of the soil that can be seen and touched as well. the color of the soil and how quickly water flows through the soil can only be examined with the physical eyes but cannot be felt.
Hence we can conclude that the question that can be answered using the sense of touch is the soil grainy.

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.
