Answer:

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

1. In a pedigree, a square represents a male. If it is darkened he has hemophilia; if clear, he had normal blood
coldgirl [10]

Answer:

a, 8

b, 3

Explanation:

If the pedigree you are referring to is the one that is attached then the answer would be:

A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.

All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.

The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
