I think animals will die even faster than plants when there’s water pollution.

I think animals will die even faster than plants when there's water pollution.

I was thinking that too. But the question asks if plants are a good indicator. Not if they are a better indicator than animals.

Which I agree is very subjective...once they mentioned 'good', one would wonder what is the reference pt.

I count 7 females daughters and grand-daughters but no solid black circles.

The question asks for NOT colour blind daughters or grand-daughters. So, Yes, there are 5 of them in total.

The parents has :
- 2 daughters & 2 sons,
- #1 daughter is married with 2 girls & 1 boy
- #2 daughter is not married
- #1 son is married with 1 daughter & 1 son
- #2 son is married with 2 sons.

So the parents have 2 daughters & 3 grand-daughters who are NOT colour blind as they are either normal or just carriers (the question asks for NOT colour blind).

Carrier means NOT colour blind. Only son #1 and grandsons from #1 daughter & #1 son are colour blind.

Cheers!

Thanks! OK, so the 2 daughters in law are not counted (obviously as the question is about heritability).

I've come across questions asking which insects have a 3 stage life cycle and which has 4 stages. Hopefully this chart will help:

How impurities can affect the melting point?

a)the melting point is raised.
b) it lowers the melting point.

Which is correct? Or both acceptable?
