Answer:
b. Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo.
Explanation:
In a double-blind test, there are two groups of participants: (1) people who are receiving the new drug and (2) people who are taking a placebo. Neither people from group (1) nor people from group (2) know what they are taking. Also, researchers recollect data from theses groups without knowing which person belongs to each group to avoid any "favoritism" caused by expected results.
Answer:
To answer this question, we use the Homeostatic Model Assessment (HOMA).
Explanation:
What is HOMA?
The principle of HOMA is that blood glucose and insulin concentrations are related by the feedback of glucose on β-cells to increase insulin secretion. The model assumes that normal-weight subjects aged less than 35 years have an insulin resistance (R) of 1 and 100% β-cell function.
In conclusion, the secretion of insulin from glucose release energy for the cell to function
The options are:
A) leaf abscission to prevent further loss
B) early flowering to try to reproduce before being eaten
C) production of chemical compounds for defense or to attract predators
D) production of physical defenses, such as thorns
Answer:
The correct answer of this question is- C) production of chemical compounds for defense or to attract predators
Explanation:
In response to attacks by herbivores, plants produce chemicals that are toxic to the herbivores which can even kill them or some chemicals can spread in the air and can attract the predators of those herbivores that attack that plant species.
Plants produce secondary metabolites that play an important role in protecting the plant from predators because they can be toxic and antimicrobial for example flavonoids, alkaloids, saponins. Plants do not get harmed by these metabolites because they have their own detoxification method. So the correct answer is C.
