Answer: The roots will produce a weak acid that dissolves the rock and does two important things (at least as far as the plant is concerned. hope this helps you :)
Explanation:
False gravity pulls rocks down
Lamarck represented the hypothesis that an organism can pass on acquired characteristics during its lifetime to its offspring. This theory was rejected, but nowadays discoveries in the field of epigenetics and somatic hypermutation confirmed part of it and highlighted the possible inheritance of behavioral traits acquired by the previous generation.
I think the correct answer from the choices listed above is option A. The main function of structural adaptations is that they help the organism survive in its environment. These adaptations are physical features of an organism like the bill on a bird or the fur on a bear.
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
