Answer:
d. Researchers said the flu shot reduced the risk of developing the flu when it actually didn't.
Explanation:
A Type I Error can be defined as the error that occurs in hypothesis when a researcher rejects the opposite of his hypothesis even though the opposite of his hypothesis is correct or true. Type I Error can also be called a False positive.
In the question above an hypothesis was carried out by researchers to determine if getting a flu shot would reduce the risk of developing a flu.
The truth is " Getting a flu shot actually reduces the risk of developing a flu"
But the researcher hypothesis test result that would result in a Type I error says "Researchers said the flu shot reduced the risk of developing the flu when it actually didn't".
This result of hypothesis test of the researchers above is a rejection of truth (the truth is an opposite of the researchers hypothesis test) and it would result in a Type I Error.
The rapid speciation of mammals as a result of the availability of new habitat due to the extinction of the dinosaurs 65 million years ago is an example of adaptive radiation.
Answer:
The osteoblasts, which should have been building the new bone
Explanation:
Osteoblast are the cells that build bones by secreting the extracellular matrix for bone tissue. These cells secrete components such as collagen fibres and inorganic electrolytes that together make the matrix of bone tissue. Absence or inactivity of these cells could prevent the formation of new bone after fracture. Hence, doctors should target osteoblasts.
