Facilitated diffusion does not use cellular energy.
Since the transportation of molecules occurs through the concentration gradient, it doesn’t use cellular energy for transportation of molecules.
False there may be two or more dependent variables in a well designed experiment
Answer:
<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%.
</h2>
Explanation:
As given,
Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.
Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.
Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%
A-----C ----------B
A---C= 2%
A----B= 35%
B---C= 33%
So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.
If the locus C is as, A---35---B--33----C ; A-----B------C
A-----B= 35%
B------C= 33%
A-----C= 33+35= 68%
As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.
1.) A persons genes are found in their chromosomes. The correct answer is D, your chromosomes. The correct answer is D.
2.) The shape of DNA is called a double helix. The strands run opposite each other and twist together. The correct answer is B.
3.) The relationship between a chromosome and DNA is that chromosomes are made of DNA. The correct answer is A.
4.) One thing that parents pass on to their offspring is genes. For example, hair color, eye color, skin color. The correct answer is A.
Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
