Explanation:
Geologists use the law of superposition to determine the relative ages of sedimentary rock layers.
Answer:
The correct answer is "It prevents spontaneous muscle's contraction".
Explanation:
Muscle contraction is produce by the interaction of actin and myosin filaments. Basically, myosin binds to the active sites of actin, which produces a protein complex (known as actomyosin) that allows that the filaments slide past each other and generate a contraction. When troponin and tropomyosin block the active sites of actin prevents spontaneous muscle's contraction, because a nervous impulse is needed to remove the inhibitors and that myosin starts the contraction.
Answer:
The Quantum Model of the Atom 1927
Explanation:
It is the most accurate model of the atom but I don't know about the easiest to visualise. Soz :(
Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
Exocrine glands release secretions outside of the body.
One way to remember this is:
exo = outside
endo = inside
An example of an exocrine gland is a sweat gland. They release sweat (an excretion) to the outside of your body.
I hope this helps! I'm happy to answer any other questions you might have :)
