<span>Athletes with mono are typically held out of all physical activity for a period of 30-50 days after diagnosis.
Mono is a disease called Mononucleosis. It is also known as "kissing disease".
It is an infectious disease in which one's spleen rupture or enlarged, it also causes fever, sore throat etc. That's why athletes are held out of all types of physical activities for some time period. Athletes can resume their activities when all the symptoms are gone.

The answer would be storm surges. Hope this helps
Sarcoplasmic reticulum resembles endoplasmic reticulum found in other cells; they are structures that surround the myofibrils of skeletal muscle fibers. T tubules or transverse tubules run perpendicular to the axis of the fiber and extend across the surface of sarcoplasmic reticulum. It's role is to conduct impulses from sarcolemma to cell and to sarcoplasmic reticulum.
I searched for the image and it points out to the liver. According to the choices, the answer is "converting toxins to less toxic forms" as the liver functions to detoxify substances through its cells (particularly in the smooth endoplasmic reticulum) via the cytochrome p450 system. Detoxification involves 2 phases, first is Phase I wherein the p450 system makes the toxic substance more hydrophilic (it means it is easily soluble to water) and can be readily excreted by the kidneys. If Phase I is insufficient, then the toxin enters Phase II which is conjugation with other molecules to make the toxin even more hydrophilic. The liver does not produce urine and excreting salt and urea as this is the function of the kidneys. The liver's main function is not digesting foods and liquids as that is the main function of the gastrointestinal tract, but the liver aids in the absorption of fats by the secretion of bile, thereby emulsifying the fats rendering it ready for absorption.
You didn't include a list, so omit anything that doesn't appear in your instructions. Here's structures in order of blood flow:
Superior and inferior vena cava
right atrium
tricuspid valve
right ventricle
pulmonary semilunar valve
pulmonary arteries (2 - one to each lung)
lungs
pulmonary veins (4 - two return from each lung)
left atrium
bicuspid, or mitral valve
left ventricle
aortic semilunar valve
ascending aorta
