Nondisjunction is the failure of a pair of chromosomes to separate (to disjoin) during cell division (meiosis). When this happens ( in anaphase I of meiosis) two out of the four new daughter cells produced from a parent cell will have an extra copy of one chromosome and the other two daughter cells will end up missing that chromosome.
Most of the time when fertilization involves gametes with an abnormal number of chromosomes, the resulting cell does not survive to produce a new individual. However there are some cases where the individuals survive and such, when they are born end up having a syndrome caused by too many or too few chromosomes. An example is Turners syndrome caused by too few chromosomes (monosomy x) , and Down syndrome caused by too many chromosomes (trisomy 21).
Answer:
Nondisjunction is the failure of a pair of chromosomes to separate during meiosis.
Explanation:
B. Alleles segregate only in the F2 generation.
C. Alleles segregate best when two tall plants are crossed.
D. Alleles in the F1 must be Tt to have height variety in the F2.
Answer:
Alleles in the F1 must be Tt to have height variety in the F2.
Explanation:
A force is said to have done work, if it manages to cause a displacement in an object from its starting point. Power can be defined as the rate of doing work. The work can be calculated using the following formula:
Work done ⇒ Force × Displacement
The power can be calculated using the following formula:
Power ⇒ Work ÷ Time
In order to calculate the work and power, the force and distance should be known. The force and distance will help calculate the work, which will help in the calculation of the power of the object.
Hence, the answer is 'you must known force and distance to calculate both'.
Work and power, concepts from physics, are similar in that both require knowledge of force and distance for their calculation.
Work and power are both concepts dealing with energy in physics. The correct statement that describes how work and power are similar is 'You must know force and distance to calculate both.' To calculate work, the formula is work = force x distance. For power, which is the rate at which work is done, the formula is power = work/time. Although time is included in the calculation for power, it's not required in the calculation for work. Thus, force and distance are the key common components needed for both calculations.

b. Are more likely to achieve high social status
c. Are more likely to hold white collar jobs
d. Are less likely to hold low paying jobs
The correct answer is (a) Poverty stricken people are less able to enjoy society's benefits.
The benefits of society includes many facilities such as financial benefits, or assistance for education, assistance for unemployment and many more. The poor people lack these kinds of facilities because they do not belong to a proper commodity that are served by these kinds of facilities. These kinds of facilities are only enjoyed by the elite class of the society.
One of the consequences of poverty is that poverty stricken people are less able to enjoy society’s benefitssuch an an education.
Poverty refers to.the inability of individuals to be able to provide for the basic needs of life such as food, clothing and shelter effectively.
Poverty has a lot of negative consequences which include;
Therefore, one of the consequences of poverty is that poverty stricken people are less able to enjoy society’s benefits.
