Answer: 50 kilometers
Explanation:
From the question, we are informed that the Pacific plate is moving at a speed of 5 centimeters per year. The number of kilometers that the Pacific plate will travel in 1 million years would be calculated as:
= 5 × 1,000,000
= 5,000,000 centimeters
Since 100000 centimeters = 1 kilometer, we would convert 5,000,000 centimeters to kilometers. This will be:
= 5,000,000 / 100,000
= 50 kilometers
Answer:
The correct option is A.
A. blocking transmission of impulses from the spinal cord to thalamus
Explanation:
Local anesthetics, like lidocaine and novocaine, reduce the perception of pain by blocking transmission of impulses from the spinal cord to thalamus because local anesthetics they first bind to ion channel in the nerve cell and then inhibit function of the ion channel present in the membrane of nerve cell known as sodium channel. This later cause blockage of nerve impulses at the site where the injection was given from the spinal cord.
Answer:
A
Explanation:
Genetic mutations randomly occur in the population of cells. If, by chance, there is a mutation that gives the bacterial cell resistance to an antibiotic, then that mutation will remain in the population.
This is because it gives the cell a competitive advantage (because it is more likely to survive than its non-resistant counterparts). If it survives, it will divide and pass the mutation on to its daughter cells, which will survive. This keeps happening until an entire population will carry the mutation.
I think it is extrusive but I am not completely sure
Answer:
D. They are genetically identical to the original cell
Explanation:
Two identical diploid daughter cells are produced by mitosis. (Diploid just means that the cells each have 23 pairs of chromosomes). Hope this helps!
