Answer:
If both parents do not have sickle-cell anemia, than the possibility is low.
Explanation:
If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.
If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.
When both parents have sickle cell anemia, their child will definitely have it.
PMI is very important in forensics because having a time of death can help with the identification of human remains and can support or deny the stated actions of suspects in the crime.
Answer:
C) Interaction increases the survival and reproductive rates of mutualistic species.
Explanation:
A) Mutualism offer more biodiversity to a community.
Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.
B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.
Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.
D) Mutualistic interaction lessens competition in communities where it is present.
Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.
E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.
Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.

Answer:
The correct answer is option D. "Null hypothesis".
Explanation:
Null hypothesis is characterized by stating that there is no difference between the specified populations, which is the opposite of the alternative hypothesis that states that there is a difference between the populations. Since the hypothesis included in the question states that "There will be no difference in the number of adverse events...", it is concluded that is an example of null hypothesis.
