Answer:
25%
Explanation:
The possible genotypes and phenotypes are:
- EE or Ee: thick eyebrows
- ee: thin eyebrows
- FF or Ff: free earlobes
- ff: attached earlobes
Tom and Jessica have thick eyebrows and free earlobes. Tom's mother has attached earlobes, so Tom must have inherited an <em>f</em> allele from her, and because he has free earlobes he must be heterozygous<em> Ff. </em>We assume Jessica is homozygous for free earlobes <em>FF</em>.
Tom's mother and Jessica's father have thin eyebrows, so they are both <em>ee</em> and therefore both Tom and Jessica must be heterozygous <em>Ee</em>.
From the above information, Tom has the genotype EeFf and Jessica is EeFF. If you do a Punnett Square of this cross, you'll get that the probability of having a child with free earlobes and thin eyebrows (eeF_) is 25%.
Answer:
c. 3, 5, 1, 4, 2
Explanation:
1. (3) food substance dissolves in saliva
2. (5) food substance enters taste pore and attaches to receptor on gustatory hair
3. (1) gustatory cell depolarizes
4. (4) neurotransmitter released by gustatory cell
5. (2) action potential stimulated in gustatory neurons
<em>Saliva has digestive functions that help food to be easily swallowed. We need saliva to taste foods because it dissolves the chemicals. The sense of taste is called gustation. We taste something with our tongue and then sensations would be carried via the facial (VII) cranial nerve. One of the newest taste to be described is umami. </em>
