<span> Acids like acid rain that hits rocks and plants and affects them are examples of chemical weathering. Roots growing in cracks in rocks can also be considered to be physical weathering. </span>
Answer:
UV radiation may cause negative regulators (tumor suppressors) to be under-expressed. UV radiation may cause positive regulators (oncogenic) to be over-expressed.
Explanation:
I found this on a quizlet. So credits to them- :)
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.
Explanation: fish and frog they both live in the water. duck and tuttle both live on land and in the water.
