Answer:
C) wear a lead protective shield when having teeth XRAYS
Explanation:
<span>Everyone’s DNA are different because they are different
people. One part of DNA are your genes. The genes are what you look like, hair
color, eye color, everything that you can
get from your parents. Even if you have a twin, it’s not necessary that you two
would have the same genes. For example, one could have green eyes and the other
could have brown eyes.

Answer:
If the active site is altered, the enzyme can no longer perform its catalytic activity
Explanation:
Changes in temperature or pH alters the structure of the enzyme. Enzymes have catalytic activity that lowers the activation energy required for a reaction to proceed.
Enzyme catalytic activity is facilitated by the active site - a specific region of the enzyme where the reactants bind.
At the active site, the conditions are optimal for the reaction to take place (the active site gets the reactants in the perfect position to make contact and react).
If the structure of the active site is compromised, it won't have catalytic activity anymore and won't be able to catalyze the reaction
Answer:
4.index fossils, intrusions, and cross-cutting relationships
Explanation:
There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.
Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.
Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.
Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.
Inner planets have a shorter revolution time because they have a far shorter distance to travel.
