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.

icang [17]

No, the sickle-cell anemia allele won't be eliminated by natural selection.

Sickle-cell anemia trait is controlled by a single gene and the allele (S) for sickle-cell anemia is a harmful autosomal recessive.

It is caused by a mutation in the normal allele (A) for hemoglobin (a protein on red blood cells).

Heterozygotes (AS) with the sickle-cell allele are resistant to malaria, a deadly tropical disease. It is common in many African populations.

In these areas, (S) carriers have been naturally selected, because their red blood cells, containing some abnormal hemoglobin, tend to be in sickle shape when they are infected by the malarial parasite.

Therefore, they are more likely to survive and reproduce. This keeps the S allele in the gene pool.

vodomira [7]

Answer:

b. Some carbon dioxide will move from chamber A to chamber B.

Explanation:

The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
