1 answer:

6 0

The earliest vertebrates resembled hagfish and lived more than 500 million years ago. As other classes of fish appeared, they evolved traits such as a complete vertebral column, jaws, and a bony endoskeleton. Amphibians were the first tetrapod vertebrates as well as the first vertebrates to live on land.

Skeletal surveys are most useful in detecting occult fractures in which age group

Katen [24]

The radiologic skeletal survey is most useful tool for detecting occult trauma fractures in children younger than 2 years old. A current policy states that skeletal survey is mandatory in all cases of suspected child abuse because younger children are easier to lift, shake, throw, pull and fall. Moreover, occult fractures can be detected by bone scan though; bone scan is not specific for fracture but still most useful in detecting occult rib fractures.

Height in humans generally shows a normal (bell-shaped) distribution. what type of inheritance most likely determines height? se

Arturiano [62]

I believe it is a combination of polygenic inheritance and environmental factors. Several genes control the height in humans, giving an overall normal distribution. Environmental factors on the other hand such as nutrition smooth out the curve. It is therefore important to note that Human height is a quantitative, or metric trait, that is, a characteristic that is measured in quantity, and is controlled by multiple genes and environmental factors.
