Answer: Pretty sure its B
Explanation: When lithospheric plates move apart, it is called a divergent boundary. Mid-Ocean Ridges are found at divergent boundaries.
The other options don't make any sense as the answer.
Answer:
Telescope also known as "spyglass"
Explanation:
In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.
The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.
Answer: 4.6 billion years.
Dehydration is the loss of too much water in our body It can be categorized into three types: isotonic, hypotonic and hypertonic. Isotonic dehydration is the most common, which pertains to equal concentrations of the extracellular and intracellular fluids. In this type of dehydration, about same amount of electrolytes and water are ;pst from the body. Hypertonic dehydration is more serious and a very risky IV fluid to administer. This type of dehydration occurs when more electrolytes are lost than water from the body. So, there must be an intake of a fluid more concentrated in electrolytes so that it will cause the water from inside the cells to be attracted to the extracellular fluid. The last type of dehydration, hypotonic dehydration, is the opposite of hypertonic. This is when more of water is lost than electrolytes. So, the fluid to be administered is less concentrated relative to the fluid inside the cells.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
