Any subjective evidence of disease. In contrast, a sign is objective. Blood coming out a nostril is a sign; it is apparent to the patient, physician, and others. Anxiety, low back pain, and fatigue are all symptoms; only the patient can perceive them.
Answer:
transcription
Explanation:
mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. The process of making mRNA from DNA is called transcription.
They posses the following traits: vertebrae, bony skeleton, four limbs, and amniotic eggs
Phylogenetic trees present common traits to animals in similar phylums.
These trees characterize traits by having the animal ABOVE the trait. Take these few examples from here: primates and rodents and rabbits are the ONLY ones with hair and crocodiles and birds are the ONLY ones with eggs with shells.
Now that you know this, look at the 4 types of animals that must have the similar traits. Look for the characteristics that are below them. They are all above the following: vertebrae, bony skeleton, four limbs, and amniotic eggs. These are the traits that all the organisms similarly have.
For a better understanding, any animals BELOW the traits do NOT have the traits, take for example that sharks and ray-finned fish are below four limbs, meaning they don’t not possess this trait.
Im pretty sure its A, I know this because the question is asking which on is an insertion for the original DNA sequence. A inserts a C in between the G-G.
Your elbow is considered to be a hinge joint. Your ankles and wrists are also considered examples of a hidge because they move in a way similar to a doorhinge.
