Answer: Magma originates in the lower part of the Earth's crust and in the upper portion of the mantle. Most of the mantle and crust are solid. Magma that cools quickly forms one kind of igneous rock. When igneous rocks undergo weathering and erosion, they are broken into smaller pieces of sediment. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. ... The sediment is dropped, or deposited, in landforms. Over time, sediment accumulates in oceans, lakes, and valleys, eventually building up in layers and weighing down the material underneath. This weight presses the sediment particles together, compacting them. Water passing through the spaces in between the particles helps to cement them together even more. Some examples of sedimentary rocks are limestone, sandstone, siltstone, shale, conglomerate, and breccia. Most sedimentary rocks contain either quartz or calcite. Way down inside the Earth, it very hot and there is a lot of pressure. It's so hot and there is so much pressure that rocks that get pushed deep into the Earth actually change. This process is called metamorphism. ... Some rocks get pushed down so far underground that they melt and become molten rock called magma. It's so hot and there is so much pressure that rocks that get pushed deep into the Earth actually change. ... Igneous rocks like granite can turn into gneiss (pronounced 'nice') and sedimentary rocks like limestone can change into marble when they are pushed down into the hot pressure-cooker inside the Earth.
Explanation:
Answer: exocrine glands
Explanation: Exocrine gland secrete substances to an epithelial surface through a channel.
The sebaceous and sweat glands associated with the skin also secrete substance to skin surfaces via ducts/ channels and are classified as endocrine gland. There are two glands in the human body Exocrine gland and Endocrine gland.
Endocrine gland secrete substance into the bloodstream directly. Examples of exocrine glands are sweat, salivary, mammary, sebaceous, and mucous.
liver and pancreas are both exocrine and endocrine glands simultaneously.
As exocrine gland, the liver secrete bile and the pancrease secrete pancreatic juice into the gastrointestinal tract through channels. While as endocrine gland they secrete other substances directly into the bloodstream.
Answer:
The most important responsibility of an individual is to conserve energy and prevent them from being unnecessarily wasted......
Explanation:
Answer: The main reason why only 2 molecules of NADH is formed during glycolysis when it appears that as many as a dozen could be formed is because during glycolysis,most of the free energy that are available from the oxidation of glucose remains in one of the products of glycolysis known as pyruvate which acts like glucose but doesn't undergo metabolism.
Glycolysis is the splitting of sugar molecules into useable/ manageable forms,it can also be seen as the aerobic catabolism of sugar inorder to produce energy in the form of ATP,NADH and PYRUVATE.The following are the products of glycolysis; pyruvate,2 molecules of ATP and 2molecules of NADH.
Pyruvate are used in aerobic respiration or anaerobic respiration if oxygen is not available.
Hm, I would think disease because sunlight is food, moist soil is water and it's not overcrowded so it has enough space....
