How might human anatomy be different today if the forerunners of humans had never inhabited the forest canopy

Explanation:

Humans would likely have never gained opposable thumbs because there would be no need to grasp as well as the shoulders because there would be no reason to move our arms in any direction.

Scenario 1:

Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.

Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)

What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)


Scenario 2:

Mike was adopted, and his biological family history is unknown. Although he is healthy, he would like some understanding of his genetic makeup, including potential health risks and genes that he could pass on to his children. Mike has heard about commercial laboratories that can compare segments of your DNA to those of people with common hereditary diseases in order to give you some idea of how susceptible you are to the diseases. The results of these types of tests are highly inconclusive. If Mike’s DNA showed that he shares similarities in a segment of DNA with people who have a given disease, his chances of developing that disease or passing it on to his children may be slightly elevated, but they are not 100 percent. These tests can cost more than $2,500 and are not covered by many insurance companies.

Do you think that Mike should undergo the genetic tests? Explain your answer. (2 points)

What are potential pros and cons of having such tests done? (5 points)

Describe how the availability of these genetic tests might affect the frequency of genetic diseases in individuals and populations. (3 points)

Which is our body part help us to maintain balance.

Which graph represents selection that may lead to reduced variation in a population?
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection.
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops.
A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed.
A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points.

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)
