A twin study was conducted to ascertain the genetic contribution to exam anxiety. It was found that in monozygotic twins the con

cordance for exam anxiety was 90% and in dizygotic twins it was 55%. What does this suggest about the contribution of genetics to this trait?

Answer:

A higher rate of concordance in monozygotic twins in comparison to dizygotic twins is a proved evidence of the contribution of the genetic constituent as monozygotic twins are genetically more identical in comparison to dizygotic twins. The monozygotic twins share all the genes in common and dizygotic twins on average share half of their genes in common.  

Thus, the concordance in monozygotic twins is more in comparison with that of dizygotic twins, which shows the contribution of genetics to this trait.

Explain
Tema [17]
Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance

TRUE/FALSE
kotykmax [81]

Answer:

False

Explanation:

A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.

Which one of the following statements does not accurately describe vibrations? 
brilliants [131]
The correct option is A.
When an end of a tuning fork that is vibrating is placed against a table, it produces a sounder that is dramatically louder than the original sound produced by the vibrating tuning fork. At this stage, the tuning fork is forcing the table to vibrate at its own frequency. Thus, the statement in option A is not true.
