Answer:
Natural selection
Explanation:
The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.
1. One societal issue that scientists will be able to address using the sequence of the human genome is reduction in the number of disable children born.
Using the sequences of human genome, scientists will be able to detect when a woman is carrying a defective or disable baby, this will allow decision to be made whether to abort the fetus or to keep the pregnancy. This will reduce the number of disable children born and reduce the amount of government resources that are been spent on this sector of the society.
2. By using human genome to assess the risk of giving birth to defective babies, the ethical considerations that will arise include the following:
i. Is it good to abort babies? Is that not murder?
ii. Who will make the decision to abort? The parents or the doctor? what of if the parent want to keep the pregnancy despite the risk?
These ethical questions will need to be addressed depending on the situations that surround the event.
3. Principally, the government ought to be the one to regulate how the human genome sequence is used by scientists. There ought to be a standard which give clear directives on what can be done and what can not be done.
But depending on the situation of the research involved, if human subjects are going to be used, then their consents must be obtained before the research is carried out. For instance, in the issue of pregnancy risk assessment described above, the woman's consent must be obtained before the pregnancy is aborted.

This question is incomplete because the options are missing; here is the missing section:
Which procedure should Juan use to test his hypothesis?
A. Survey northern and southern residents about the birds in their areas.
B. Observe the direction the birds fly when they depart in the winter.
C. Tag the hummingbirds with transmitters and track their movement.
D. Set up observation posts in the south to verify the time of year that birds arrive.
The answer to this question is C. Tag the hummingbirds with transmitters and track their movement.
Explanation:
To prove or disprove his hypothesis about birds Juan needs to test the direction hummingbirds fly to during the winter because only in this way he can know if the birds fly to the South as he thinks or they go to a different place. Moreover, this can better be tested through precise instruments such as trackers because these will register the movement of birds and clearly show if they are going to the South. Moreover, others such as the opinions of residents or the initial direction when birds migrate might be inaccurate.
Answer:
Gravity?
Explanation:
Gravity is a force that causes anything with matter to fall to the ground.
The skeletons may be similar but it usually focuses on one part. Meaning that the homologous structure would be a monkey paw, or the flipper of a whale.
They would be in the same classification. Such as humans are called homo sapien sapien. The family would be homo if I'm correct, meaning that if scientists are able to use the DNA of that structure to relate it to a common ancestor.
It would be true. Or if it's a multiple choice question, we need to know the choices.
