7. You and your lab partner are doing an experiment in the physiology lab. Each of you has an isolated muscle cell and you are supposed to stimulate it with an electrode as soon as its absolute refractory period ends. Your partner has a cardiac muscle cell and you have a skeletal muscle cell. Which one of you will use your electrode more times in one minute

I will use the electrode on the skeletal muscle cell more times in a minute than my partner will.

Explanation:

Based on the information given, an electromyograph tracing can be used on order to know when to use the electrode for the scenario explained.

An electromyograph is simply a machine that is used for the detection and the recording of the electrical potential that's been generated by muscle cells when such muscle cells are activated.

Due to the fact that a skeletal muscle cell while my partner has a cardiac muscle cell, I'll have to use the electrode on the skeletal muscle cell more times in a minute than my partner will.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

d. groundwater flows through the subsoil and deposits minerals.
