A mutation in DNA subsequently causes a premature STOP codon in the mRNA strand. What happens when the ribosome reaches a STOP codon? The ribosome puts a stop amino acid in protein
The ribosome detaches from the mRNA strand
The ribosome and mRNA are stuck together
The tRNA takes over for the ribosome

How is an organism's genotype related to its phenotype?
variations in genotype lead to different phenotypes
they are not related
variations in phenotype lead to different genotype

Organisms that reproduce sexually tend to have this advantage over organisms that reproduce asexually
They have less genetic diversity because they only mate with one other parent
They can reproduce faster than asexual organisms
They have more genetic diversity because each offspring has genes from two parents

A white mouse is crossed with a black mouse. All the offspring were grey. The genes for fur color in mice show .
Complete dominance
Incomplete dominance
Recessive inheritance
Codominance
I got everything else but I need help with these 4 questions

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

The diagram shows the structures of horse and cat forelimbs. what does the diagram suggest about the evolutionary relationship between these two mammals? a. they have homologous structures, indicating a common ancestor. b. they have analogous structures, indicating a common ancestor. c. they have homologous structures, indicating that they do not have a common ancestor. d. they have analogous structures, indicating that they do not have a common ancestor.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
