<h3><u>Answer;</u></h3>
That parental traits that were not observed in the F1 reappeared in the F2.
<h3><u>Explanation</u>;</h3>
- Mendel accounted for the observation that traits which had disappeared in the F1 generation reappeared in the F2 generation by proposing that traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
- <em>I</em><u><em>t was important that Mendel examined not just the F1 generation in his breeding experiments, but the F2 generation as well, because parental traits that were not observed in the F1 reappeared in the F2.</em></u>
Answer:
500 m/s
Explanation:
Velocity (v) = wavelength (λ) x frequency (f)
V = 10 x 50
V = 500 m/s
Answer: seen below
Explanation:
1) The olfactory receptor can recognize and respond to different ordor, For humans, most odorant molecules are made up of combinations of 5 kinds of atoms: these are, carbon, hydrogen, oxygen, nitrogen, and sulfur.
2) yes, scent is subjective. This is because there is likely variation in people's sensitivity to odor or personal appreciation of different odors. Not everyone smells the same thing.
3) The two proposed theories for the mechanics of scent recognition are; vibration theory and shape theory which is also called the lock and key model. The main problem with one of Turin theories is that we can't currently predict odor character from vibration any better than we can from shape. That is we are still terrible at predicting ordor character from molecular structure.
4) Science has contributed to the creation of scented products and perfumes by having chemical Mixtures Tested in labs and addition of substances for smell.
5) Scents or fragrances are used in cosmetology as perfumes, lotions, shampoos, face washes, body cream, conditioners, etc. Cosmetologist need to be aware of scents and fragrances because if a perfume had a scent that did not smell right then no one would want to purchase their product.
We can control pollution by
(i) By Making workplaces no-smoking zones and banning cigarettes advertising.
(ii) By Strictly penalties for consumers and firms who break the regulations.
(iii) By Setting minimum standards in the workplace for health and safety.
