qaws [65]

Answer:

cline

Explanation:

  • When a measurable gradient is seen in a particular character across population living in a geographical range then this gradient is termed as cline.
  • The clines can either be abrupt or continuous across a given geographical range.
  • Clines arise due to two factors - gene flow as well as selection.
  • In a map the clines are represented by lines that indicate the changes in character from one end to another across a geographic range.
  • Therefore, the B blood group frequency changes in a map across eastern Asia and far western Europe form a pattern which is termed as a cline.

What does it mean if you find a skeleton and all of the sutures on the skull are fused? Be specific by using ages in your explan
mr Goodwill [35]

Answer:

If the scull is fused the individual is not a baby

Explanation:

If a skull is found, one of the first things to do is classify by age. Careful observation will show that the skull may or may not be fused. Noteworthy observations could give the professional an idea of the individual's age.

In the womb when the bones of the skull are being formed thre are typically seven bones with gaps in between. This allows the infant to pass safely through the birth canal but giving way to squeezing and the contractions of the uterus. After the child is born there are still remaining gaps. These gaps allow the brain to grow and develop without pressure from the skull. This can often be observed by a soft spot on the top of the infant's head sometimes called a "mole"

Around two years of age, these bones begin to fuse and harden.  Therefore if a skull is found with fused bones, the individual can be placed to be older than two years of age. Other determining factors such as teeth etc can narrow down the individual's age.

Which of the following will NOT cause mass extinction?
aliya0001 [1]
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
