Explanation:
<u>D. 6</u>
There are two forms of the gene, CTGT and TGTC, called alleles. These have undergone 3 crossover events, which may create two separate copies.
Thus 2 × 3 (# of events)= 6 new alleles
The interchange of chromosome segments, including homologous non-sister or identical chromatids. Crossing over happens at chiasmata, where non-sister chromosomes are fused together.
Further Explanation:
DNA variants on chromosomes,may have different forms called alleles. DNA, which is a genotype, is transcribed into mRNA and then converted into amino acids that are linked together by rRNA to form proteins that make up the morphology of the individual.

Answer:
If bird song promotes an individual's ability to attract a mate and reproduce, then the song has an <u> function</u>
<u />
Explanation:
Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.
Natural selection takes place and is determined by the fitness of an individual
, it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.
A dehydration synthesis reaction is needed in the synthesis of a polymer bond
True, Bright-field microscopes are used for most microscopic work.
The body that activates appropriate coordinating structures is department with primary legal authority.
The non-stafford act incidents are those incidents in which the recovery requirements exceeds the capacity of the individual and community but not the state.
This act is activated by department with primary legal authority coordinating structures appropriate to that authority.
The non-stafford act plans strategy for recovery through:
- Supporting the development of local Business Recovery Plans for individual impacted businesses,
- Develop a State recovery strategy to ensure the unified coordination of State and
- Federal agencies supporting impacted jurisdictions.
The non-Stafford act assess the needs of the individuals and communities for federal technical assistance.
