Answer:

a) legs

Explanation:

Based on these characteristics it can also be said that this species would have legs. This is due to this new species having paired lateral fins. That is because paired lateral fins refer to the pectoral and ventral fins, which are corresponding to the fore and hind legs of the higher animals. Meaning that this new species would have had to have legs if they had paired lateral fins, and a bony skeleton would help corroborate this finding.

A population of 150 individuals has an allele frequency of 0.2 for the dominant allele (H) and a frequency of 0.8 for the recess
Amanda [17]
Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!

denis-greek [22]
The appropriate response is Klinefelter. Klinefelter disorder is a chromosomal condition that influences male physical and psychological advancement. Its signs and side effects differ among influenced people. Klinefelter disorder influences 1 in 500 to 1,000 infant guys. Most variations of Klinefelter disorder are substantially rarer, happening in 1 in 50,000 or fewer infants.

Do all exothermic phase changes have a negative value for the entropy change of the system?
spin [16.1K]
Yes! This is because of the law of thermodynamics which suggests that as energy is transferred or relayed into other forms of energy, entropy increases. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
