Answer: C. Scientists working for a German corporation develop an herbicide that kills 98% of unwanted vegetation in their lettuce crops, but does not damage the lettuce.
Explanation:
The Green Revolution, refers to the research and technological initiatives that brought about an increase in agricultural production. In this situation, the use of pesticides, herbicides, and high yield varieties led to an increase in the production of crop.
The best situation that indicates a farmer using Green Revolution agricultural method is a scientists working for a German corporation develop an herbicide that kills 98% of unwanted vegetation in their lettuce crops, but does not damage the lettuce.

You have 400 mg of a radioisotope with a half-life of 5 minutes. How much will be left after 30 minutes?
A 6.25mg
B 12.5 mg
C 100 mg
D 50 mg
You have 400 mg of a radioisotope with a half-life of 5 minutes. The time that will be left after 30 minutes is 6.25 mg. The correct option is A.
What are radioisotopes?The radioactive isotopes of an element are called radioisotopes. They can alternatively be described as atoms with surplus energy in their nucleus or unstable neutron-proton combinations.
A radionuclide is an unstable nuclide with too much nuclear energy. The extra energy can either be transferred to one of the nucleus' electrons to release it as a conversion electron, released from the nucleus as gamma radiation or used to build and emit a new particle from the nucleus.
Nuclear transmutations: natural radioactivity. Less than a hundred radioisotope types are recognized, yet there are more than a few thousand. Accelerators and Research Reactors for Man-Made Radioactive Isotopes.
If the half-life is 5 minutes, then 30 minutes is equivalent to 6 half-lives. So, after six successive half-lives, the 400 mg of the radioisotope would have a mass of 400(0.5)⁶ = 6.25 mg.
Therefore, the correct option is A. 6.25 mg.

Subsistence agriculture is always characterized by
A. double-cropping of specific grains
B. Extensive use of land
C. Production only for family consumption
D. Production only for trade
E. Irrigation and inorganic fertilization
Answer: production only for family consumption
Explanation:
Subsistence agriculture is always characterized by production only for family consumption. The correct option is C.
What is Subsistence agriculture?A subsistence farmer is one who does not produce agricultural goods in big quantities and instead uses what is produced for his or her own consumption rather than small, medium, or large-scale commercialization.
Because just a small number of items are needed to satisfy the producer's demand, this condition negates the need for specialized technology for large-scale production.
Cost efficiency is one advantage of subsistence farming. It does not require the significant capital that a commercial farmer would have otherwise needed, which is the reason. The equipment used is frequently accessible and reasonably priced.
Therefore, the correct option is C. Production is only for family consumption.

Rachel is studying the causes, consequences, and treatments of mental illness. She samples 100 people diagnosed with generalized anxiety disorder. She provides each individual in her sample w
either a new untested drug, a placebo, or a nocebo (which occurs when a person expects negative side effects of a medication), Rachel measures sympathetic nervous system arousal a week bef
and a week after the study. The results of the study appear in the following graph.
70
Answer:
part a
random assignment ensured each participant had the same chance of being in each group so that means that the results can be more trusted as it leaves less room for data skews based on unfair grouping of participants.
the research method used was an experiment it was not effective, because as shown in the graph the results from the placebo and new drug are the the same so there was no affect on the levels of arousal with the new drug.
elements that limit the generalizability of her study include environmental factors of participants, length of time using drug, small sample size, and limited information about participants. these all affect the generalizability because each of these elements could vary greatly among test and especially in just a 100 person sample size it is hard to conclude that the results will be the same with people everywhere with GAD.
part b two physiological reactions she could have used are increased heart rate and blood pressure because these are typical signs of symptomatic nervous system arousal.
part c GABA blocks impulses between nerves in the brain cells and with general anxiety disorder there is lots of stimuli's and when GABA is taken it can help create a calming affect which reduces anxiety and helps people to relaxed rather than be anxious or on edge.
The relationship on the graph is showing that to have a good performance the optimal amount of arousal must be present because having too much arousal, like in many cases in which Rachel is studying, can cause anxiety and stress, and on the other side having not enough arousal can lead to consequences of not being able to sustain attention and lacks motivation.
