We may apply Fleming's Left Hand Rule of Electromagnetism to determine how a charged particle behaves in a magnetic field. However, because the gamma rays do not have a charge on them, like alpha particles and beta particles do, they are not deflected.
Gamma rays are electromagnetic waves and its is a characteristic of electromagnetic waves that they have no charge.
I believe it’s A in the question
Answer:
d. pxp +2pq
Explanation:
The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:
p² + 2pq + q² = 1
where, p = dominant allele
q = recessive allele
Here,
p² represents frequency of homozygous dominant genotype
2pq represents frequency of heterozygous genotype
q² represents frequency of homozygous recessive genotype
Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
Answer:
d. Fire ants spread by winged members and by hitching rides so a single colony can cause infestation.
Explanation:
An invasive fire ant colony can be very disastrous to the population of organisms in a locality. They cause massive competition with the native species thereby infesting them and destroying the native population.
Fire ants spread by winged members which makes a single colony to cause severe damage to the native specie. Often times, as they become endemic, they manifest as the dominant specie in a particular location.
Answer: Increased reproductive success of individuals with the ability to survive in a variety of water temperatures
Explanation: Natural selection establishes that the conditions of an environment favor or hinder (select) the reproduction of organisms according to their characteristics. Natural selection was proposed by Darwin as a means to explain biological evolution.
The trait subject to selection must be inheritable.
There must be variability of the trait among the individuals of a population.
The variability of the trait must give rise to differences in the survival or success of the player, making certain characteristics of the new appearance can be extended in the population.
The accumulation of these changes over generations would produce all evolutionary phenomena.
