During a windstorm, a large old tree fell in the forest. As it came down, it trapped a young sapling about 5 meters tall underneath it. The top of the
Auxin and gibberellin in the sapling's stem will cause a gravitropic response in the sapling, and its stop will grow upward even though it is held down.

Answer:
Frequency of allele A1- 0.41
Explanation:
In Hardy weinberg equilibrium,
P refers to the dominant allele
q refers to the recessive allele
The allele frequency will be p+q=1
The genotypic frequency is- P²+q²+2pq=1
P²= genotype of dominant trait ( A1A1)- 77
2pq= genotype of heterozygotes (2pq)- 65
q²= genotype of recessive trait (A2A2)- 123
Total number of offsprings= 77+ 65+ 123
= 265
Now to calculate allele frequency of A1=

= 77/265 + 1/2( 65//265)
= 0.290+ 0.122
= 0.413
Thus, 0.41 is correct.
Answer:
B. gelisols
Explanation:
tundra soils are formed at high latitudes
If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.
