There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dominant (B) allele is 0.7. What is the expected number of heterozygous individuals if the total population size is 500 individuals?
Answers
Answer:
210
Explanation:
Frequency of dominant allele is represented by "p"
and frequency of recessive allele is represented by "q"
Given
Thus,
As per Hardy Weinberg's second equation of equilibrium -
Substituting the given values in above equation, we get -
So the total number of heterozygous individual is equal to

When energy flows from one trophic level to the next trophic level most of the energy lost as heat in the process.
Explanation:
The food chain is transfer of energy in the form of food from one trophic level to next in an ecosystem.
Energy flows from at each trophic level when organism of higher level consumes organism of the lower level.
Energy flows at each trophic level by 10% Rule which states that only ten percent of the energy will be transferred on at each trophic because of the following reasons-
1. Energy is lost in the form of heat at each step
2. Only consumable energy by organisms is transferred at the trophic level.
3. Energy is lost through different biological processes such as respiration.

A mother has either AA or AO genotype. Since her daughter has OO genotype, the one O allele is from a father and one is from the mother. Thus, mother must have allele O. So mother's genotype is AO.
A mother with AO genotype will pass to her son either A or O allele. Since son is type B negative, it could inherit from mother only O allele. Son's genotype is BO. This means that he inherited from the father B allele.
Talking of Rh, her son is type B negative. A negative Rh phenotype contains both recessive alleles r.
Therefore, the son genotype is BOrr. In terms of the alleles for the I locus, it can be represented as

The Great Pacific Garbage Patch is an environmental problem of the Pacific ocean water. It is accumulated with a trash of 10 meters deep non-degradable plastics. These plastic wastes can trap marine animals and contaminate the quality of water.
The Great Pacific Garbage Patch will be difficult to physical clean up because it actually lies in the international water, and no single nation is responsible for it's creation, also the filtering out of the plastic will effect the marine animals and diversity of marine phtoplanktons and zooplanktons.
Therefore, all of the above

According to Newton's Second Law of Motion, when a force acing on the object is unbalanced, the object will accelerate. So, the correct option is (A).
What is Newton's Law?
1. Newton's first law of motion
This law is also called the law of inertia. This law states that an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line unless acted upon by an unbalanced force.
2. Newton's second law of motion
This law states that force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force which imposed on it. The force acting on object is directly proportional to the mass and acceleration.
F = m.a
Where, F- force
m - mass
a - acceleration
3. Newton's third law of motion
This law states that when two bodies interact with each other, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
Above example is the explanation of second law of motion.
Thus, According to Newton's Second Law of Motion, when a force acing on the object is unbalanced, the object will accelerate. So, the correct option is (A).
