The amount of kinetic energy depends on the mass and the speed. The kinetic energy of an object is directly proportional to its mass and speed. So, if the mass of a body increases, it’s kinetic energy also increases even if the velocity remains constant. So, yes, Robert’s kinetic energy will be twice as much. Also, think of it this way-since Robert has twice the mass as his sister, he will also need twice the amount of kinetic energy to run in the same velocity as his sister.
It takes the muscle time to act once it receives a response from the nerves. It also takes time for the electric impulse to pass between gaps in the nerves (synapses).<span />
Good coronary circulation nourishes the heart and reduces the risk of a heart attack. Coronary arteries supply blood to the myocardium and other components of the heart. They originate from the left side of the heart at the base of the aorta. The heart muscles needs oxygen-rich blood to be able to carry out its functions.
Answer:
Rapid increases in water temperature cause extensive fish kills
Explanation:
Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.
Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
Answer:
Explanation:
Natural selection is based on Darwin’s observation that individuals most likely to survive and reproduce are those with traits best suited to their current environment.
