Use the next five answer choices for the next 2 questions, not all answer choices are used and there is only one correct answer choice for each question

A) The Gene Pool

B) Allele Frequency

C) Disruptive Selection

D) Directional Selection

E) Balancing Selection

1) The sum total of all Alleles at all Loci within a population

2) The percentage of each possible allele for a single locus within a population

3) Individuals whom are recessive homozygotes for Sickle Cell Anemia cannot produce the normal red blood cell shape because of a single mutation in the Allele that codes for Hemoglobin protein primary structure

A) True

B) False

4) Galapagos Island Iguanas have.......

A) Jaws and skull specialized for scraping algae from rocks in the ocean

B) Jaws and skull specialized for accessing fruit and hunting insects

C) Coloration for camouflage in the forest canopy

5) DNA Replication is called SEMICONSERVATIVE because...........

A) Both daughter double stranded DNAs consist of parent strands ONLY

B) Both daughter double stranded DNAs consist of daughter strands ONLY

C) Both daughters double stranded DNAs consist of one parent and one daughter strand

Answer 1

1) gene pool in a population is the collection of all alleles in the population for all loci so the answer is A) Gene pool

2) Allele Frequency percentage of each possible allele for a single locus within a population so the answer is B) Allele Frequency

3) sickle cell anemia is caused by a point mutation in the sixth codon of the beta chain of hemoglobin which changes the amino acid glutamate (hydrophilic) to valine (hydrophobic) this change is in the primary sequence of the protein that is in the amino acid sequence so the statement is true.

4) Galapagos Island Iguanas eats green algae only so the answer is A) Jaws and skull specialized for scraping algae from rocks in the ocean

5) DNA replication is semiconservative because in the newly synthesized DNA molecule one strand is parental and the other is newly synthesised so answer is C) Both daughters double-stranded DNAs consist of one parent and one daughter strand
