The answers 3 and 4 are the correct ones...
uysha [10]3 years ago
3 0
3 and 4 are correct. A compound is a collection of two or more molecules, whereas a molecule is a collection of two or more atoms. 1 is not true because its talking about two atoms together which is a molecule. 2 is not true because it is still talking about two atoms which is still a molecule. 3 is true because molecule are subunits of compounds. 4 is true because elements and atoms are the same thing, and two or more atoms is a molecule.

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.

Are crickets producers, consumers, or decomposers?
____ [38]
Hey there!

Here is your answer:

<u>The proper answer to this question is option B "consumers".</u>

Reason:

<u>Producers are organisms like plants they produce food for other organisms. (Plants) Consumers are organisms that eat other organisms. (Some insects, mammals, etc)  Decomposers are organisms that decompose on raw flesh, or grow on fertilizer. (fungi) </u>

Also...

<u>Crickets would be consumers because they eat plants and plants are organisms therefore the cricket is consuming the plant. </u>

Therefore the answer is B.

If you need anymore help feel free to ask me!

Hope this helps!

Compare and contrast transcription and translation
tangare [24]
So first transcription takes place which is a RNA that translates DNA Template. So an example would be DNA has AGCGTCAATCTA this will be translated into UCGCAGUUAGAU

Then this message is send off to become a protein with the MRNA which then comes Translation which is the process of converting UCGCAGUUAGAU into a protein and the way it’s done is by this message going through a ribosome and gets translated by TRNA that brings amino acids together to form codons and create your protein.
