The nutrients that coats your nerves is something called myelin. Those like vitamin B and D can help out myelin sheath.
Answer:
All four planets: Mercury, Venus, Earth and Mars are inner planets or also referred as terrestrial planets. Those are the planets orbiting closest to the Sun.
Earth is the largest of the Inner Planets, with a diameter of 12,756 km and Mercury is the smallest with a diameter of 4,878 km (3,031 miles). They have solid surfaces and thin/no atmospheres. Mercury is one of the densest planets in the Solar System. Venus is the brightest object we see in the sky, has a thick toxic atmosphere and is the hottest planet. Earth is the only planet that has liquid water.Mars surface contains iron-rich materials and has the most interesting terrain: the surface is very old and filled with craters.
Explanation:
Answer:
Productivity is refers to the rate of generation of biomass in an ecosystem. The difference between net and gross productivity is that gross productivity is is the overall rate of energy capture while net productivity is is lower, adjusted for energy used by organisms in respiration/metabolism.
Explanation:
I would say estuary, because that's where a fresh water river and an ocean meet, and that leads to a transition between salt to fresh water.
Answer:
It was an experiment to prove that DNA was made of genes. They discovered that protein was NOT genetic material.
Explanation:
"In their experiments, Hershey and Chase analyzed what happened when phages infect bacteria... They found that <em>when phages infect a host bacterium, the phages first attach themselves to the outside of the bacterium. Then, a piece of the phage enters the bacterium and subsequently replicates itself inside the cell. After many replications, the phage causes the bacterium to lyse, or burst, thereby killing the host bacteria.</em> Scientists classified the replicating piece as genetic material. Scientists also found that phages contained two classes of biological molecules: DNA and protein.
Hershey and Chase utilized a technique called radioactive isotope labeling. Chemical elements can exist in different structural forms called isotopes. Isotopes of the same element are nearly identical, but scientists can distinguish between them by experimental means. One way to differentiate between chemical elements with different isotopes is by analyzing their radiation. Some isotopes are less stable than others and give off radioactive signals that scientists can detect. Hershey and Chase marked phages by incorporating radioactive isotopes of phosphorus and sulfur in those phages. They allowed some phages to replicate by infecting bacteria, specifically Escherichia coli, or E. Coli, that scientists had grown in radioactive sulfur. The researchers let other phages infect and replicate in E. Coli that scientists had grown in radioactive phosphorus. DNA contains phosphorus, but not sulfur, whereas protein contains sulfur, but not phosphorus. Therefore, when Hershey and Chase marked phages with radioactive isotopes of those elements, they placed separate, distinguishable tags on the protein and DNA parts of the phages."
