Answer:
Your answer is D). Like most cold-blooded animals, geckos' bodies are unable to maintain a homeostatic body temperature on their own, therefore they must bask in the sun in order to increase their body heat, and hide in the shade when it's too hot.
The question is the following :
<span>What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.
The correct answer is A
In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.</span>
Answer:
sorry but i need the points
Explanation:
IT WOULD BE 15 CAUSE 10+5 IS 15 AND ITS THE SAME AMOUNT GOING IN AS OUT AND 15 IS GOING OUT SO 15 IS GOING IN.
Potential energy = (mass) x (gravity) x (height) .
To raise the 20kg block 6 meters, you need to give it
(20 kg) x (9.8 m/s²) x (6 m) = 1,176 joules
of potential energy.
Your machine takes 2,000 joules of energy to give the block
the 1,176 joules that it takes.
Your machine is only (1176 / 2000) = 58.8% efficient .
The other 'missing' 824 joules of energy doesn't just disappear.
It heats the machine, and the air around it. The final result is
that when you use that machine to lift blocks, you have to use
even MORE energy, to blow cool air on the machine and prevent
it from overheating and breaking.
