B. Fiber
Fiber is the indigestible portion of food from plants.
Answer:
B each new layer has a new bit of the story to tell and you can see sequential time with each strata
A. 1. Embryological development is very similar for many animals so it would differ a lot from the DNA.
2. embryological evidence is a poor substitute for DNA evidence because of it's almost universal progression. It would be more difficult to see difference in embryos vs via DNA
D. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. Like the arthralgus of a whale that looks very similar to a terrestrial mammals tells us that the whale evolved from land mammals
C. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Explanation:
PCR allows for the analysis of DNA fragments through the comparison of the base pairs each molecule contains, which can then be used for genetic screening and the identification of individuals and DNA fragments
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
