<h3><u>Answer;</u></h3>
D) <em>The more dense oceanic plate subducts under the less dense continental plate. Subducted plate melts due to heat and friction. Melted plate, now magma, rises up to the surface.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Volcanoes may be formed at convergent plate boundaries or at divergent plate boundaries. </u></em>
- <em><u>When two tectonic plates collide, they form a convergent plate boundary. Normally, one of the converging plates that is the dense oceanic plate will move beneath the other, which is the less dense continental plate a process as subduction. </u></em>
- <em><u>The friction between the plates in the subduction zone as a result of constant movement, melts the Earth's crust causing the underneath rocks to turn into magma.</u></em>
- <em><u>The magma creates great pressure and rises towards the surface of the earth, and on reaching the surface it is called lava, and a volcano is formed.</u></em>
Answer: salt intake increases the sodium level in the blood and will make the body retain excess water thereby giving the heart more work to do.
Explanation: Eating salt increases the quantity of sodium in blood and it creates an imbalance in the sodium and potassium levels. The high level of salt reduces the ability of the kidneys to excrete water. Too much sodium increases blood pressure because it holds excess fluid in the body and that results to an added burden on the heart. Excess sodium intake will increase risk of osteoporosis, stomach cancer, stroke, heart failure and kidney disease.
The result is a higher blood pressure due to the fact that the body will have the tendency of retaining more fluids because of the excess salt.
Mutations occur when DNA makes a mistake in cell division. This could change the appearance and other disorders of a person. An example would be sickle cell anemia.
D
More biodiversity often means a more stable food web as their is more to fall back on
Answer:
a- pharmaceuticals
Explanation:
Pharmaceuticals is a demanding and challenging field which tests your knowledge of DNA technology and medicine because they are the ones making drugs for new diseases and such. Thus they need to know how to prepare those drugs to target certain cells or organelles and such and need to know how it will affect the human being and/or other living beings
