Protein channels + no energy spent + following concentration gradient = passive transport via facilitated diffusion :)
Answer:
Three influenza pandemics occurred during the 20th century: the 1918-19 “Spanish flu,” the 1957-58 “Asian flu,” and the 1968-69 pandemic or “Hong Kong flu.” In 2009, the World Health Organization (WHO) declared a global pandemic of H1N1 flu.

Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available
Therefore
Total genetic variance (VG) = VA + VD
= 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
= 100
Recall,
Selection response is heritability multiplied by selection differential.
That is
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30
= 430 Units
