Answer: A mutation Changes by its mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
Explanation:
A mutation changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.
Answer:C
Explanation:
Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.
It has a value of -50 and -75mV.
Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)
In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .
These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.
The movements of these ions across the membranes generated electrical potential difference for action potential.
Answer:
The model that does the best job of showing osmosis is "Thomas. Student-drawn membrane model within a rectangular box. From left to right there is an upper and lower line spaced moderately apart."
Explanation:
Osmosis: this is a process of which molecules of a solvent pass through a semipermeable membrane from a lower concentrated solution into a more concentrated solution.
The correct answer would be C. both types of energy pyramids contain the same species of organisms. This would be the incorrect one because aquatic and terrestrial ecosystems do NOT have the same organisms living in them.
Answer:
A) Fats provide 12 kcals of energy per gram.
