If xylem is the non-living vascular tissue in plants that transports water from the roots to the rest of the plant, and constitutes the rings on a cross section of a tree, how does it grow with the re Which molecule, when moving across a plasma membrane, would require the most ATP...
The atmosphere is the gaseous envelope that surrounds our planet. Approximately 78% of this gas is nitrogen and 21% is oxygen, while argon makes up less than 1%, and the remains are split between other gases (like carbon dioxide and methane) and water vapor. ...
The "Molecule Cloud View" module allows you to visualize a group of molecules as their respective van der Waals surfaces within 3D datasets, specifying their positions and orientations. To use this feature, you need a molecule template, such as one from the Protein Data...
Breathing creatures take it up and then change it into carbon dioxide, which plants use as a carbon source and release oxygen into the environment. Hydrogen Hydrogen bonds only contain one proton per atom. One of the most prevalent elements in the cosmos is hydrogen. Hydrogen makes up the ...
s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes from renewable sources, there are no greenhouse gas emissions. Renewable hydrogen is also known...
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
Mineralogy – The Study of Minerals Chapter 3 What is a mineral? What are the properties of minerals? What are minerals composed of? How doChlorine gas molecule, Cl
called a molecule. Atoms and molecules make up almost everything that people can see, and interact intimately with energy, often in the form ofelectromagnetic radiation. It was soon realized that electromagnetic radiation can be released when the electrons in an atom transition to a lower energy ...
The chemical structure of water makes it an excellent medium for life.Water is actuallyquite simple,bus the way the water molecule is formed gives water its unique properties.The water molecule is made up of two hydrogen atoms and ane oxygen atom.They form a polarmolecu...
Every molecule making up every cell's membrane contains phosphorous (the membrane molecules are calledphospholipids), and so does every molecule of ATP (the main energy source of all cells). Potassium makes up 1 percent to 2 percent of the weight of any plant and, as an ion in cells, is...
