Abiotic for desert: Sand
Biotic for polar: Polar bears
Biotic for desert: Cacti
The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.
Explanation:

2. A eukaryotic cell
<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
