The plants are then consumed by animals, bacteria and other creatures, which are themselves eaten by other creatures.
Explanation:
The object is a living thing; option B
<h3>What are living things?</h3>
Living things are things that have life in them.
The basic activities of living things are given as follows:
- movement
- reproduction
- nutrition
- Irritability
- growth
- excretion
- respiration
Considering the information in the chart about the object:

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
