A.  The waves would be exactly the same at points A and B.

Explanation:

The seismic waves at both point A and B would be exactly the same at the two points.

Seismic waves are elastic waves that spreads out concentrically in all directions from their source.

  • Both S and P waves are body waves that moves within the earth.
  • In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
  • At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.

Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.

A population of a tree snail species has different patterns in their shells. These slight
Alja [10]

Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.

(03.05 MC) In which of the following ways is DNA replication different from DNA transcription? (2 points) New cells can only be
Softa [21]
The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.<span />
