Diabetic retinopathy develops because abnormal blood vessels grow into the space adjacent to the neural layer of the retina, causing cellular damage and ultimately blindness.
Which of the following cells form the deepest layer of the neural layer of the retina?

A) amacrine and horizontal cells
B) ganglionic cells
C) rods and cones
D) bipolar cells

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation

Achange in direction without a change in speed is called velocity

What is the purpose of transcription? a. to copy the nucleotide in dna b. to form rna molecules from dna c. to produce a nucleic acid sequence from an amino acid sequence d. to link amino acids together to form stands of protein
