<span>Carbohydrates are more easily metabolized than lipids. However, on a gram-for-gram basis lipids provide cells with more energy. Lipids are the sources of the highest amount of energy, but they are much more difficult to process by our bodies compared to things such as carbs.</span>
Mass × Acceleration
60 kg × 5m/^s =
300
The answer is C. 300 N
The accurate statements to the signal transduction pathways are as follows:
1. A receptor changes conformation upon attachment, conducting a signal across the cell membrane.
2. A second messenger may carry a signal from the cell membrane to an organelle.
3. Signal transduction cascades, often involving protein kinases, amplify a signal intracellularly.
4. A receptor may pass on a signal by associating with another protein or by functioning as an enzyme.
5. A ligand, like hormone, combines with a specific cell surface receptor on a target cell.
6. Phosphatase eradicate phosphoryl groups from polypeptides, monitoring the response of the cell.
Answer:
Lung caner. If you smoke, you will have a higher risk of getting lung cancer.
DNA being placed with DNA polymerase and nucleotides and resulting in new copies is not an opinion or inference because the fact is, new more DNA was found in the test tube after adding the enzymes and nucleotides than before the addition. DNA sequencing of the new copies would have shown that the sequences of the new DNA are identical to the original DNA that was first placed in the test tube. Also, other experiments would have shown that adding other different kinds of molecules or enzymes does not, in fact, produce new strands of the original DNA, nor should it be able replicate the DNA at all.
