Suppose the fictional condition lycanthropy is an autosomal dominant disorder that causes an affected person to have a strong ph
hodyreva [135]

Answer:

Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.  

Explanation:

As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.

In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.

The image shows rock strata from three different regions on Earth. Identify all the layers that contain an index fossil
FrozenT [24]

The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.

The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.

By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.

What is the appropriate dose of 1:10,000 (0.1 mg/ml) concentration of epinephrine for endotracheal administration to a baby weig
vlada-n [284]
I believe the appropriate dose will be 1.5 mL, 
Epinephrine is used for both allergic reaction and heart attacks, in an effort to increase blood flow through veins and to reduce swelling in airways. When epinephrine is recognized by receptors on smooth muscles, it causes airway-blocking muscle constriction to subside. Other drugs that may be administered by the endotracheal route include atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate.
