Answer:
500
Explanation:
According to the given information, the total number of albino people in the population= 1000/4 = 250.
Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.
The frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5
Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%
Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
Answer: Desert spans the annual mean temperature range.
Explanation:
Biomes are large ecological community of plant and animal on the earth surface that have characteristics for the environment they live in. A desert is an example of biomes. It is a barren area of land where there is high temperature and low precipitation (rainfall). It is a place where living conditions is difficult. Lact of vegetation exposed the areato direct sunlight and there is increased temperature. Desert are formed by weathering process I.e the breakdown of rocks into smaller particles through the activities of some agent like water or wind.
Answer:
Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science.
Answer:
cool
Explanation:
just cool that's good for you.
Organisms that reproduce sexually have greater genetic and thus characteristic variations, and so, are able to withstand more selection pressures if they so happen to change or become greater. This increases the chances of survival for that species itself.
Organisms that reproduce asexually are genetically identical to each other. They are unlikely to withstand any changes in selection pressures.
Hope this helps! :)
