The correct answer is D.
Seafloor spreading is a process of creating seafloor crust out of volcanic materials that are emerging from the Earth's core at the mid-ocean ridges.
This is made possible by the moving of Earth's tectonic plates.
Answer:
The defective CFTR protein changes ion influx and efflux across the body's cell membranes, which ultimately changes the internal environment of these cells. This change contributes to each cell's production of proteins through transcription and translation.

There is an electrical gradient and there is a concentration gradient.
1.) Chemical gradient better known as concentration gradient is much more powerful and compelling than the electrical gradient.
2.) Water is a polar molecule, meaning one side it positively charged while the other is negatively charged. This polar charged molecule causes water to have a weaker electrical gradient, thus the water has to move on its concentration gradient.
The correct answer is B. After filtration, the lymph from lymph node travels to the subclavian veins, through efferent lymph vessels. The whole transport process is affected by smooth muscle contraction, changes in pressure and opening/closing of valves.
They are rich in hydrogen and helium, they have unlimited supply of hydrogen, they have a strong gravitational pull.
Explanation:
Space where huge size of gaseous and dust cloud is present is called nebula. It is mainly made of hydrogen and helium. Nebula exist in the space which is between the stars and it is call as interstellar space.
Helix nebula is closest nebula which is near the earth. It’s distance from earth is about 700 light years.
Dark nebulae are very dense as well as cold. Nebula can be divided into dark nebula and bright nebula. The gas which is present between the stars is always combine with solid grains cosmic dust.
