Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
Explanation:
The middle ear is an air-filled cavity that sits between the tympanic membrane and the inner ear. The middle ear also consists of three tiny bones called ossicles , the round window, the oval window , and the Eustachian tube .
The answer in this question is known as antisepsis. Antisepsis is the chemical agents that is used directly on exposed body surfaces to destroy or inhibit vegetative pathogens. Antisepsis is defined as the practice of using antiseptic to eliminate the micro-organism who causes of having a disease.
The magnification of the eyepiece and objective lens used to obtain 600X magnification in the virtual microscope is 6.10.
<h3>What are microscope lenses?</h3>
Compound microscope lenses are called objective lens and ocular lens. The objective lens is a lens that is installed very close to the object being observed. The ocular lens is very close to the observer's eye.
With this information, we can conclude that 600X magnification in the virtual microscope is 6.10.
