The correct option for this question option (A) The first study was a controlled experiment, while the second group was an observational study.
In an observational research, participants are measured or surveyed without any attempt to influence them. In a controlled experiment, participants or objects are divided into groups, and one group is given a treatment while the other is not.
Experimental study, allocate treatments to groups at random so that the researchers can determine the causal (cause-and-effect) relationship. What sets apart this research is the randomization of the treatments (observational and experimental). Here, we conduct an experiment and change the subject's surroundings to assess the response (dependent) variable. The experimental study's evidence is seen as being more reliable than the observational studies.

The complete question is:
In human testing controlled experiments can be tricky and can have ethical considerations. In a controlled experiment investigators apply treatments and then observe the effect of the treatment compared to a control group that does not receive the treatment. When this is not possible investigators may rely on observational studies where investigators simply observe effects without applying any treatment, in observational studies there is no human intervention. Consider the following example In one study subjects were randomly given either a placebo or 1000 milligrams of vitamin C daily, and the number of colds they came down with during a winter season was noted. In a second study people responded to a questionnaire asking about the average number of hours they sleep per night and the number of colds they came down with during a winter season.
A) The first study was a controlled experiment, while the second group was an observational study
B) The first study was and observational study while the second group was an experiment.
C) Both studies were observational studies
D) Both studies were controlled experiments

Fill in the blanks below, replacing the "?" with the correct answer.
1. When the muscle cell is in a ? , the two strands are not in contact with one another.
2. When your nerves send a message to your muscles, these two protein strands reach out and touch one another. The movement that occurs gives us the name ? .
3. In addition to actin and myosin, your muscles also need ? to provide energy to fuel the sliding movement that occurs when the muscle contracts.
4. Proteins can change shapes when they come into contact with charged particles called ? .
5. When a muscle is at rest, there are two tiny proteins called ? and ? that are wrapped around the actin.
6. There are also ? molecules stuck to each one of the ? heads when the muscle is in a relaxed state.
7. It is the ? , ? , and ? which keep the myosin heads from extending and attaching to the protected actin strand.
8. During periods of rest, the muscle builds up an abundance of ? ions that will be used when it is time for the muscle to contract. The cell gets these ions through the calcium pumps of the ? , which is wrapped around each sarcomere.
9. When the muscle receives a signal from the nerves around it, the signal travels down the cells membrane in folds called ? .
10. When the signal reaches the SR, the calcium pumps ? wide and the ? ions begin to flow.
11. Calcium ions bind to the troponin. This causes the troponin to shape and ? around the actin, which moves the tropomyosin out of the way leaving binding sites exposed.
12. With the binding sites open, the myosin heads ? and ? to the actin.
13. This attachment is called a ? . The contact causes the myosin heads to bend toward the center of the sarcomere, shortening the overall length. We call this sarcomere shortening a ? .
14. When there is no longer a nerve stimulus, the calcium ions ? back inside the SR, an ATP molecule ? the head of the myosin, and the troponin and tropomyosin return to their resting positions.
15. It is the energy that is released by the ATP molecule on the myosin head that fuels muscle ? .

nterior of the blood vessel. the exposed fibers and chemicals released from the endothelial cells that line the blood vessel attract platelets, which start to form a plug and release
Collagen fibers in the blood vessel's wall are made visible to the interior when the blood vessel's wall is damaged. The blood vessel's endothelial cells' exposed fibers and chemicals draw platelets, which begin to form a plug and release additional chemicals.
The majority of the arteries, veins, and capillaries in the brain, skin, lung, heart, and muscle are made of continuous endothelium. Tight connections hold endothelial cells together and keep them attached to a continuous basal membrane. The endothelium is an essential metabolizing and endocrine organ that plays a significant role in the regulation of immunology, inflammation, and angiogenesis, as well as the control of blood fluidity, platelet aggregation, and vascular tone. The inner surface of blood vessels is covered by endothelial cells, whereas the outer surface of internal organs and the body is covered by epithelial cells.

which of the following is not a true statement most hormones systems function under a positive feedback system
Among the following that is not a true statement is (A) most hormones systems function under a positive feedback system.
Most hormone systems don't have positive feedback. Positive feedback regulates some hormonal systems, like the female reproductive cycle, but not most. Many hormone systems use a negative feedback system to stabilize the internal environment by counteracting or reducing input. In response to increased blood cortisol levels, the hypothalamus-pituitary-adrenal axis inhibits adrenal gland cortisol secretion.
Positive feedback processes increase the initial stimulus, causing a quick and brief reaction. Positive feedback in hormonal regulation causes female ovulation by increasing luteinizing hormone (LH).
