Answer:
Magnification is simply found by multiplying the power shown by 10
10x has a magnification of 100 times (low power)
43x has a magnification of 430 times (high power)
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
Answer:
Evolution.
Explanation:
Evolution is the gradual change that occurs in the genetics of an organism. Change in environment of an organisms play an important role in evolution. Evolution leads to the change in the physical structure of an organisms that is compatible to that environment so gradual change occurs in the genetics of the moth having gray wings which helps the moth to hide in the ash.
Answer:
The frequency of individuals with the dominant phenotype is 0.83.
Explanation:
We are provided with:
Black allele has completed dominance over brown allele
T. no of dogs (dominant)= 2000
No. of black dogs (dominant) = 1660
From Hardy-weinberg equilibrium
Frequency of individual - (individual/ Total population)
Frequency of black dogs = 1660/2000 =
0.83
So, The frequency of individuals with the dominant phenotype is 0.83
The nucleus controls everything in the cell
