A mutation can either be passed down as a hereditary trait, but most mutations of the gene can be triggered by something such as radiation from the sun, or if an error is made in cell division as DNA copies itself

Answer:

B. The rating number means it will protect you that many times longer than without sunscreen

Explanation:

The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.

While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.

Which compound plays a pivotal role in both the first and last step of the TCA cycle? a. pyruvate b. oxaloacetate c. oxalate d.

vitfil [10]

Answer:

Option b oxaloacetate is the right one.

Explanation:

There are major eight steps in TCA cycle. Oxaloacetate plays a pivotal role in first and eight steps of cycle.

Step 1. In the first step of the citric acid cycle, acetyl CoA joins with a four-carbon molecule, oxaloacetate, releasing the CoA group and forming a six-carbon molecule called citrate.

Step 8. In the last step of the citric acid cycle, oxaloacetate—the starting four-carbon compound-is regenerated by oxidation of malate. Another molecule of NAD+ is reduced to NADH in the process.
