Answer:
9/32 Pink, Tall and Normal individuals Rr Tt Nn
Explanation:
<u>Available data:</u>
- Red color RR
- Pink color Rr
- White color rr
- Normal NN and Nn
- Symmetrical nn
- Tall TT and Tt
- Dwarf tt
1st Cross:
Parental) rr TT NN x RR tt nn
F1) 100% RrTtNn
2nd Cross:
Parental) Rr Tt Nn x Rr Tt Nn
Knowing that these three genes assort independently, then we can infer that the F2 will have the next phenotypic proportions for each gene:
RR= 1/4 Red
Rr= 2/4 Pink
rr=1/4 White
TT + Tt= 3/4 Tall
tt=1/4 Dwarf
NN + Nn = 3/4 Normal
nn=1/4 Symmetrical
- The proportion of the F2 plants that will resemble Rr Tt Nn (Pink, tall, Normal) in Phenotype
Rr= 2/4 pink
TT + Tt= 3/4 Tall
NN + Nn = 3/4 Normal
2/4 x 3/4 x 3/4 = 18/64= 9/32

The correct option is: E. 70 square meters
Explanation:
Pulmonary alveoli is described as the cup-shaped hollow cavity, found in the alveolar sacs of mammalian lungs.
The alveolar membrane, also called the respiratory membrane, allows the exchange of gases. Across this membrane, carbon dioxide is released from the capillaries into the alveoli and oxygen is diffused from the alveoli into the capillaries.
<u>About 300 million alveoli are present in the lungs of a human, which makes about 70m² of surface area. </u>
