The cardiac muscle has intercalated disk that allows rapid transmission of the impulse. This will allow the cardiac muscle to have a coordinated way. The heart muscle has pacemaker that will spread the signal in regular time. The transmission of impulse is also controlled by a few checkpoint like the bundle of his to make the signal to the Purkinje fiber of left and right ventricle at the same time.
Microorganisms that live in severe habitats, such as very
hot, acidic, or salty environments are called extremophiles, which are
bacteria, archaea and eukaryotes. They are the most successful organisms
because they can adapt in any environment. They can live in oceans, rivers,
soil, and even inside a human’s body.
In the summer the northern hemispher gets the most light and the further north you go or the higher latitude the more daylight you get. The Equator is more half and half. The north pole, the sun never sets.
<span>Winter the further north you go, the more night time you get. Equator is still more or less half and half.
