Answer:

d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days

Explanation:

In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.

In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.

choli [55]

The right answer is glutamate

Glutamate is a major excitatory neurotransmitter associated with learning and memory.

It is also associated with Alzheimer's disease whose first symptoms are felt in memory.

Most people unknowingly consume monosodium glutamate (MSG), a commonly used food additive.

An experiment was done on healthy patients, giving them 12 grams of glutamate. It was found that the experience led to headaches, nausea or jaw pain in 50-60% of cases.

It was also measured the level of glutamate contained in the muscles of patients with jaw problems. The tests concluded that the most painful muscles were those containing the highest levels of glutamate.

According to him, one of the keys to chronic pain could lie in the development of drugs that reduce the rate of glutamate.

(PLEASE ANSWER ASAP, WILL MARK BRAINLIEST)
noname [10]

The answers include the following:

  • Arrow F represents transpiration.
  • Matter is conserved through the process in which carbon from carbon dioxide leaves and enters into the atmosphere.
  • This process is a recycling of carbon in the carbon cycle because it involves it travelling the atmosphere into organisms in the Earth in a repeated manner.

<h3>What is Carbon cycle?</h3>

This refers to the  biogeochemical cycle in which carbon is  reused through different types of mechanisms and actions.

This process involves carbon travelling the atmosphere into organisms in the earth in a repeated fashion through methods such as respiration, transpiration etc which is how recycling works.

This is therefore the reason why it can be regarded as the process which involves matter and conservation and recycling.
