Answer:
option C: B = 0.48; b = 0.52
Explanation:
Of the 50 mice, 12 were homozygous black (BB), 24 were heterozygous black (Bb), and 14 were brown (bb).
BB Bb bb Total
12 + 24 + 14 = 50
the formular for alleleic frequency (p) is (BB+ Bb/2) / total,
q = (bb + Bb/2) / total
Allelic frequecy of B (p) is (12 + 24/2) /50 = 12 + 12 = 24/50 = 0.48
Allelic frequency of b (q) is (14 + 24/2) / 50= 14 + 12 = 26/50 = 0.52
check p + q = 1; 0.48 + 0.52 = 1
The right answer is 2HgO → 2Hg + O2
Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.
In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.
Answer:
The conditions that will not cause conduction deafness is <em>damage to cochlear hair cells, </em>option B.
Explanation:
Conduction deafness occurs there is an alteration that blocks the transmission of sound from the external and middle ear to the inner ear. It is a mechanical problem in the ear canal or the middle ear.
The outer ear is the external portion that collects sonar waves and directs them to the inner ear. Three structures compose the external ear, these are the auditory pavilion, the ear canal, and the eardrum. Damages in any of these parts might produce conduction deafness.
The middle ear is located between the eardrum and the oval window of the inner ear, to which it transmits sounds. the middle ear is composed of three little bones called ossicles, the oval window, the circular window, and the Eustachian tube. Any damage or alteration in this area will also cause conduction deafness.
There are different causes of deafness, such as earwax plug, <u>damage in the eardrum,</u> otitis, traumatisms or malformations, tumors, outer ear infections, <u>imflamation</u>, fluid accumulation, among others. Any of these might impede the properly sound conduction, thus the sound can not reach the inner ear.
