Answer:
During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.
Explanation:
I think there’s is 36 protons
Answer: 4; tt
Explanation: The two lowercase letters indicate that there are two recessive genes. If there is one uppercase letter and one lowercase letter, that would mean that it is heterozygous (as there is one dominant and one recessive gene).
Answer:
So where then did all the carbon that living organisms are built of come from? It turns out that most of the carbon we use today came from a collision with another smallish planet about 4.4 billion years ago.
The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. Earth's solid crust acts as a heat insulator for the hot interior of the planet. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements. Description Magma or magma, meaning in Arabic, magma, magma, or magma, which is a mixture of fused silicon materials, or in other words with. Magma forms under the Earth's crust or other layers of the Earth.
