Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution?
A. The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
B. The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.
D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slits.
An__ is a variation of a gene.
Answer:
Genetic variability refers to a species's genetic variation as a whole. Specific changes in DNA fragments or genes are referred to as genetic variants, and each mutation of a gene is referred to as an allele.

Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.
Natural selection inhibited the eggs from hatching before expected because this trait is negative in terms of survival and reproduction.
How does natural selection work?Natural selection is a natural process that causes evolution over time. This mechanism implies only individuals with traits that represent an advantage for survival and reproduction will prevail over time, which causes the traits of these individuals to become dominant.
For example, if in a population of deer male deer with big antlers are more likely to survive and reproduce, it is expected after some generations this trait is dominant.
How does natural selection work in the red-eyed tree frog case?In this situation, we know that if an egg hatches before time the embryo is not likely to survive. This means this trait is a disadvantage in terms of survival and reproduction, and due to this and as a result of natural selection the trait is not dominant.

why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?
Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

In which of the following organisms did photosynthesis most likely first
evolve?
A. Algae
B. Prokaryotes
C. Plants
D. C4 plants
The following organisms did photosynthesis most likely first evolve - B. Prokaryotes
Sufficient evidence indicates that eukaryotic photosynthesis originated from endosymbiosis of cyanobacterial-like organisms
ultimately these prokaryotes became chloroplasts in eukaryotic cells.So the evolutionary origin of photosynthesis is to be found in the bacterial domain.The geological record indicates that this transforming event took place early in Earth's history, at least 2450–2320 million years agoThus, The following organisms did photosynthesis most likely first evolve - B.
