Facilitated diffusion
i also included a photo of the explanation of facilitated diffusion. i hope this is helpful
Answer: the answer should be Decreases as the habitat is increasingly polluted. Now I'm not 100% but this answer seems to be the one that makes the most sense.
Sorry if I'm wrong but I think this is correct. Hope I have helped.
Answer:
<h2>c. Both alleles are recessive, but they must be located at different gene loci.</h2>
Explanation:
Given:
If he inbred normal mice and obese mice , all the F1 mice are normal.
F1 and F1 interbred : 8 are normal and 2 are obese.
obese and obese = all are obese.
hence O1 proved as recessive allele.
in second experiment :
O2 is proved as recessive allele.
But when both obese mice of different laboratories are inter-crossed, all the offspring are normal, hence it is proved that Both alleles are recessive, but they must be located at different gene loci.
