If it’s referring to sea floor spreading then the answer is D, I hate analogies but I think it’s talking about the mantle convection that slowly breaks away at the lithosphere
Answer:
True
Explanation:
Point mutations arise when a single amino acid base is changed. This could cause some differences in the organism or it may not. Manufactured point mutations in model systems such as yeast offer a powerful tool to examine the function of different amino acids in a protein.
There are three types of point mutations
- Silent: these mutations have a single residue change but it does not affect the amino acid that is being coded. There is no change to the wild type
- Nonsense: will cause a stop or start or gain of start/stop codon.
- Mis-sense: will cause a change of amino acid residue. There are two types of mis-sense Conservative and non-conservative. The former will cause a change in amino acid base to one that has similar properties while the former will change to an amino acid of different properties often having different traits than the wild type.
Transcription starts at the template strand of DNA where mRNA attaches and is constructed from 5’ to 3’ direction. The nucleotides of the DNA strand is attached to either A, U, G, C ribosomal nucleotides. mRNA Dissembles when it reaches a terminating codon and then it attaches to ribosomal RNA where tRNA carries the amino and mRNA caries the code to construct proteins with the ribosome.
Answer:
B
Explanation:
hope this helps sorry if incorrect have a good rest of your afternoon :) ❤
I believe that blood pressure rises and falls in a pattern corresponding to the phases of the cardiac cycle. The maximum pressure achieved during ventricular contraction is called the systolic pressure while the lowest pressure that remains in the arterial system during ventricular relaxation is the diastolic pressure.
