Correct answer: D). The organism is buried in sediment and then dissolved by underground water
Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.
The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.
Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.
Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.
Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.
IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf
It is not possible to determine the twins' behaviors based on having this single gene
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
A. -50 degrees, it may also be 60 degrees but -50 is much more harsh
