Using evidence from the text, how can natural selection determine the survival of humans during the current COVID-19 pandemic? Please explain in 2-3 sentences. In your response, use the words: genetic variants/genes, natural selection, favorable traits This must follow a CER format (claim, evidence, reasoning)

Red numbers are bootstrap scores. Recall that any bootstrap score >= 90% is considered strong. From image attached answer the following:   Are most bootstrap scores in your tree >= 90%?   Does your tree support the hypothesis that HIV-1 is closely related to chimpanzee SIV (SIV_CPZ)? Does your tree support the hypothesis that HIV-2 is closely related to various non-chimpanzee SIVs?

If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene? Assume Hardy-Weinberg conditions. Submit your answer as it is. a) homozygous recessive individuals (q²) b) the recessive allele (q) c) the dominant allele (p) d) homozygous dominant individuals (p²) e) heterozygous individuals (2pq)

Using the model, what most likely led to the loss of white furred rabbits in the population? A) XB) C) The white rabbits did not reproduce fast enough to survive. White was a recessive trait and therefore not passed on to any offspring. The white fur was a favorable trait but was never prevalent in the population. The rabbits with white fur had less camouflage in D) the environment and were more easily preyed on by predators. 2) If this model continues, with no major changes to the environment, what do you expect to happen? XA) Rabbits will continue to get lighter over time.

Human Skin Color: Evidence for Selection Name: Jayden Bodisto Make observations of the Figure below. Then complete the portion below.

The colors on this map of the world represent Ultraviolet (UV) Index values on a particular day in September 2015. The UV Index is a standardized scale of UV radiation intensity running from 0 (least intense) to 18 (most intense). The y-axis values are degrees of latitude, which range from the equator (0°) to the poles (90° north and -90° south). The x-axis values are degrees of longitude, which range from the prime meridian (0°) to the antimeridian (180° east and -180° west).
