Answer:
water is evaporated into the air then the water molecules get too heavy and come back down as snow/rain/ect
Answer:
When warm, wet air rises, it cools, and water vapor condenses out to form clouds. ... When ice crystals form high up in the cloud, and it's below the freezing point of water all the way down, then you get snow. But when there are alternating layers of air above and below freezing, you get other types of precipitation.
Explanation:
Since there are no constructive (volcanic activity) or destructive (erosion) forces at work under the ocean, the ocean floor is flat.
True
False
False so false
Ik it cant be true because there are underwater volcanoes and the earths plates are constantly moving.

What affect do enzymes have on chemical reactions?
Answer:
Increases reaction rate by lowring its activation energy.
Explanation:
i.e If the chemical reaction completes in 5 hours it means that reaction's activation energy is very high.This factor causes decrease in rate of reaction so to increase reaction rate and to decrease activation energy enzymes or catalyst are added so now reaction will be completed in half hour.This is the importance of enzymes/catalysts.Enzyme and catalyst cann't start reaction but they increase rate of reaction and decrease time to reach equillibrium.

Which of the following best describes the relationship between the endoplasmic reticulum and the plasma membrane in eukaryotic cells?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, there is a distinct relationship between the endoplasmic reticulum and the plasma membrane. The endoplasmic reticulum are responsible for protein synthesis which are used by the remaining organelles (including the membrane) to function. The endoplasmic reticulum is also involved in lipid synthesis and has a network of tubules (which are used for carrying materials throughout the cell) that can deliver lipids into the cell membrane. These lipids are responsible for the semi-permeability function of the cell/plasma membrane.

Explanation:
Climate, salt water, tidal fluctuation and soil type are the limiting factors for the mangrove wetland community. mangrove plants only present on wetland regions where the climate is humid. It also grow on the land where saline soil is found but excess saline conditions reduces its normal growth and development. For better growth of mangrove plants, soils made up of sand, silt and clay which are rich in organic matter.

What were the major contributions of the H.M.S. Challenger to the study of oceanography? How did its expedition contribute to future studies of the ocean?
Answer:
The H.M.S. Challenger embarked from Portsmouth, England on December 21, 1872 and changed the course of scientific history. Physicists, chemists, and biologists collaborated with expert navigators to map the sea. This interdisciplinary spirit has continued to the present day. During the 4 year journey, the voyages circumnavigated the globe, sounded the ocean bottom to a depth of 26,850 feet, found many new species, and provided collections for scores of biologists.
C. Wyville Thomson led the expedition but died of exhaustion from the journey, which ended on May 24, 1876. The Challenger had zig-zagged around the globe and had visited every continent, including Antarctica.
The reports of the Challenger expedition were supervised by Sir John Murray, whose biological conclusions were of great importance to the later development of marine biology. He concluded, for example, that the deep-sea fauna was not "ancient," in that it did not resemble the faunas found in ancient fossil deposits.
Explanation:
Answer:
The H.M.S. Challenger changed the course of scientific history. The expeditions circumnavigated the world, sounded the ocean floor to a depth of 26,850 feet. Itdiscovered numerous new species, and supplied collections for hundreds of researchers over their four-year adventure. The Challenger was a corvette, a military ship that went by sail but had auxiliary steam power to help steady the ship during sampling. The expedition was commanded by C. Wyville Thomson, who died of fatigue on May 24, 1876, at the end of the voyage. The Challenger has zig-zagged its way around the world, stopping at every continent except Antarctica. Sir John Murray oversaw the Challenger expedition's reports, and his biological results were crucial to the eventual development of marine biology. For example, he decided that the deep-sea fauna was not "old" since it did not reflect faunas found in ancient fossil beds.

Invertebrates have a higher net production efficiency than mammals. Which statement most likely explains this observation? A. Invertebrates are more abundant than mammals in an ecosystem. B. Mammals maintain their body temperature; invertebrates don't. C. Most mammals are secondary consumers. Most invertebrates are primary consumers. D. Invertebrates have smaller bodies than mammals.
Answer:
C. Most mammals are secondary consumers. Most invertebrates are primary consumers.
Explanation:
Net production efficiency (NPE) refers to how efficient an organism at one trophic level is in utilizing and transferring energy to the next trophic level. Consumer organisms obtain energy (from biomass) when they feed on other organisms. They then use this energy for their metabolic activities and transfer the rest when eaten or fed on.
The net production efficiency decreases with increasing trophic level because higher organisms use more energy than lower ones. In this case, invertebrates use energy they obtained lesser or more efficiently than mammals, hence, making them have a HIGHER net production efficiency than mammals. Therefore, invertebrates are mostly primary consumers and utilize energy lesser than mammals which are mostly SECONDARY CONSUMERS.
Which three minerals are most commonly found in the igneous rock granite?
Answer:
Granites and rhyolites consist predominantly of quartz and potash feldspar; gabbros and basalts, predominantly of pyroxene and plagioclase feldspar. Other rock types have intermediate mineral compositions.
Explanation:
It is made up of sodium feldspar, potassium feldspar, and coarse quartz grains (10–50%). More than 80% of the rock is composed of these minerals.
What is igneous rock granite?Granite is a pale-colored plutonic rock that is mostly found in mountainous regions of the continental crust.
Quartz and potash feldspar make up the majority of granites and rhyolites, whereas pyroxene and plagioclase feldspar make up the majority of gabbros and basalts. Other types of rocks contain mineral compositions that are in between.
Magma, which is a molten substance that flows and hardens underground while slowly cooling, is the source of intrusive rocks.
Therefore, the majority of the continental crust is composed of granite, the most common kind of igneous rock, intrusive igneous rock is granite.
