Igneous rocks are crwated by heat and pressure they form from lava of the crust surface from melting rocks from the mantle forming bt the cooling and molten magma on earth's surface
It would be C but its been a while since i took this class so sorry if im wrong but im 80% sure its C
I believe your answer would be Echinoderms and Chordates. I hope this helps!
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.
Because the plants are blooming to early and they can freeze
