You should be able to get an entry-level job with a bachelor's degree in environmental science but to advance in this field, a master's degree is required. Alternatively, you can begin your career with an undergraduate degree in biology, engineering, chemistry, or physics.
Answer:
The correct option is B) The homologous structures are evidence of descent with modification from a common ancestor.
Explanation:
Homologous structures can be defined as similarities between organs or skeletal of organisms which suggest that they might have a common ancestor in the past. Homologous structures will have alike structures although they may be present in animals of different texa.
For example, The front legs of a frog, which is an amphibian is similar to alligator which is a reptile. This common structure show that they have homologous structures and hence might have had a common ancestor in the past.
<span>The ability to taste PTC is due to the presence of at least one dominant allele for the PTC taste gene, so a nontaster genotype should be homozygous recessive(pp). If the frequency of pp is 45%, then frequency of p would be:
pp=0.45
p= </span>√0.45
p=67%
p+P= 100%
P= 100%- p
P= 100%-67%= 33%
<span>The number of North American population that has is homozygous dominant(PP) genotype would be:
P=33%
PP= 33%^2= 10.89% = 0.1089 = 0.11</span>
