The answer is tree hope this helped :)
Answer:
C, a long absolute refractory period.
Explanation:
Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.
Answer:
Your nervous system is involved with all aspects of human function. Circulation, digestion, endocrine and excretory systems are controlled by the autonomic nervous system. The autonomic nervous function is controlled by your body with out conscious thought. Imagine having to regulate your heart rate, rate of digestion, liver, and hormones with your mind. The brain and spinal cord work together to carry out these tasks.
Breathing is another example of your body systems working together. When you breathe, you think of the respiratory system. However, think about what the respiratory system does. It delivers oxygen (nutrients) and removes carbon dioxide (waste). However, the respiratory system only exchanges these gases through the lungs. These gases need to travel throughout the entire body. The circulatory system allows the gases (and blood) to travel everywhere. The skeletal and muscular systems are also involved because they help push the blood from one end of the body to the other.
the skeletal system and its interaction with the nervous system. For example, the skull protects the brain from injury. The brain also regulates the position of the bones by using the muscular system
A third example is when a pathogen enters the body. Your immune system is responsible for keeping invaders out. When you breath in a pathogen, it can sometimes cause you to cough. Your immune system recognizes the invader and communicates to your body that it is bad. Then your skeletal and muscular system is responsible for creating the contractions to create the cough.

Don't copy it take some information.
Answer:
c. the gravitational forces due to the sun and the moon cancel each other's effect
Explanation:
The two diagrams represent Neap tides. Neap tides occur when the Sun, the Moon and the Earth are aligned at right angles. Moderate tides are formed because the bulge due to gravitational pull of the Sun cancels the bulge due to moon. The difference between the high tides and the low tides is the smallest.
Answer:
Jaundice is a symptom of cirhosis which is related to the chronic liver disease
Explanation:
Bilirubin is produced in the body when the hemoglobin protein in old red blood cells is broken down. Erythrocytes continuously undergo a (breaking apart) process. As the red blood cells disintegrate, the hemoglobin is degraded or broken into globin (the protein part), iron, and heme. The heme first breaks apart into biliverdin, a green pigment which is immediately reduced to bilirubin, an orange-yellow pigment. The bilirubin is then transported to the liver where it reacts with a solubilizing sugar called glucuronic acid. This more soluble form of bilirubin (conjugated) is excreted into the bile. The bile passes through the gall bladder then goes into the intestines where the bilirubin is converted into a variety of pigments.
Jaundice occurs when the diseased liver doesn't remove enough bilirubin, a blood waste product, from your blood. Cirrhosis, when in its late stages, can cause Jaundice. Cirrhosis occurs as a result of severe scarring of the liver caused by chronic liver disease. As a healthy liver tissue becomes damaged over time, it is replaced by scar tissue, which affects the structure of the liver and decreasing its ability to function.
