Will a female only inherit a sex linked disorder if her father suffers from the same disorder, and if her mother is a carrier fo
muminat

Answer:

The female will not inherit a sex linked disorder if her father suffers rather "have chances or the disorder if the mother is the carrier" for the disorder.

Explanation:

A female has 2 X chromosome, which she got from her parents each. The females will get the disorder or the defective gene if the mother has defective X chromosome or if the father is carrying the same disorder from his father(grandfather). In both the cases the female will be the carrier and have chances to inherit the defect to the offspring. But the female will  not affect as the  male will. As the female has 2 X chromosomes, and hence the dominant X will compensate for the error in recessive X.

Fossils almost never contain DNA. So how can we know how closely or distantly related fossil organsims are to living organisms
Nostrana [21]
While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.

How did each change to the land affect the fish in the pond?
N76 [4]
<span>Lakes and ponds are inland bodies of standing or slowly moving water. Although lakes and ponds cover only 2 percent of the world's land surface, they contain most of the world's fresh water. Individual lakes and ponds range in area from a few square meters to thousands of square kilometers. In general, ponds are smaller than lakes, though regional idiosyncrasies of naming abound—Henry David Thoreau's famous Walden Pond in Massachusetts has a surface area of 64 acres. Lakes and ponds are an important source of fresh water for human consumption and are inhabited by a diverse suite of organisms.</span>
