Just because one hypothesis may help to explain a phenomenon does not mean it is the only hypothesis that could explain it. Imag

ine you are a scientist investigating why frog populations are declining in a state county with several hundred ponds.
There could be multiple reasons why frog populations are declining in the county, and therefore, it would be wise to test multiple hypotheses. Some experiments may be observational, in which the researcher observes and measures naturally occurring variations in the dependent variable. Other experiments may be manipulative, in which the researcher directly manipulates the independent variable to test the effect on the dependent variable being measured.
Match the experiments to the hypotheses they test. Make sure to distinguish between the observational experiments and the manipulative experiments.

frosja888 [35]

Answer:

The correct answer would be calcium ion and cAMP.

Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.

The secondary messengers can be classified into three major class:

  1. Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
  2. DAG (diacylglycerol) and IP₃ (inositol triphosphate)
  3. Calcium ions (Ca⁺⁺)  

Hence, from the given options, calcium ion and cAMP would make the correct choice.

g the period of time that begins with contraction of the atria and ends with ventricular relaxation is known as: question 36 opt
Archy [21]

The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.

<h3>What is a cardiac cycle?</h3>

The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.

<h3>Cardiac Cycle Physiology</h3>

The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.
