Haploid cells are sex cells or gametes.
A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
Answer:
similarities
Explanation:
The concept of reproductive isolation relates more toward genetic similarities to distinguish between species. The barriers prevent closely related species living in the same geographical area from interbreeding. They help to keep each species distinct from the others.
<span>a and c could be true
Animals don't have peace treaties with each other and the other two options would both allow a population to increase in size.</span>
Answer:
The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.
Explanation:
Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.
This testing system is used by schools for several purposes:
• To evaluate the performance of kids during placement process.
• It is also used to evaluate abilities of dis-abled children or deferentially able children.
• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.
• In addition, the test can also diagnose brain related and neuro-psychological disorder.
Point to remember:
The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.
