Plz .what sex is the person who has the karyotype described in steps 3-4? how do you know?
2.in what ways are the mutations described in steps 5-6 and 7-8 different from those described in steps 9-10 and 11-12?
3.in steps 11-12, you saw that cystic fibrosis is caused when specific sections of both copies of chromosome 8 are deleted. on the basis of this information, do you think cystic fibrosis is a dominant or recessive trait?
4.do all mutations result in negative effects?

1. xy is a male, and xx is a female.

2.the mutation occurs when chromosomes are defected by an harfull radiation ,alpha,beta,gama etc . the cause break in chromosome .

there are certain syndromes were product of this .

also from parential generation some mutation are there.

3.it would be a recessive trait

4.mutations do not necessarily always have to be bad, sometimes plants or animals mutate with something to the situation they are in.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
