Translocation theories refer to the process that explain water transportation in plants. We found three great theories: capillarity, root pressure and cohesion. Capillarity refers to the property that displays water when encounterd with small tubes, water "sticks and climbs" through the tube. The smaller the diameter the greater the climbing. Root pressure, refers to the effect salts and minerals absorbed in root, along water, exert in the content previously absorbed. That is, the "new generation of nutrients" pushes upward nutrients previously absorbed. Finally, cohesion theory is similar to capillarity. It refers to the property water molecules have to keep in close contact, due to their hydrogen bonds. Water forms a continuum through the plant. Water is losed through evapotranspiration in the leaves, so as water is losed, water from the stem starts to move. In that way water keeps the "continuum" and fills the gap that evaporated water left.
During the carbon cycle, animals and plants add carbon dioxide to the atmosphere through cellular respiration, and plants remove carbon dioxide through photosynthesis. The burning of fossil fuels releases more carbon dioxide into the atmosphere, contributing to global warming.
Answer:
Vertebrates represents animals with backbones.
Answer:
Specifically, a glycosidic bond is formed between the hemiacetal group of a saccharide (or a molecule derived from a saccharide) and the hydroxyl group of some alcohol.
Explanation:
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
