Answer:
Inter-Tidal Zone
Explanation:
This area is known as the inter-tidal zone, where the animals must be able to withstand the sun's heat and the ocean.
Dominant allele = p
Recessive allele = q, p+q=1, since those are the only alleles which contribute to this trait
For genotype frequencies, we square both side of that equation: (p+q)2 = 1^2 --> p2 + 2pq + q2 = 1, where
p2 = homozygous dominant frequency
q2 = homozygous recessive frequency
2pq = heterozygous frequency
q2 = .09 --> q = 0.3, which is the same as 30% --> p+q=1, so p = 1-0.3 = 0.6
Or 60% of this trait within this population contains the dominant (p) allele
Selection pressures are external agents which affect an organism's ability to survive in a given environment. Selection pressures can be negative (decreases the occurrence of a trait) or positive (increases the proportion of a trait)
Answer:
antibodies bind to antigens on the infectious agent which are then destroyed by lymphocytes
