B . to supply energy for splitting the water molecules
Answer:carbon,hydrogen, nitrogen, oxygen, phosphorus, sulphur
Explanation:living things are characteristized by hierarchy in their organisation.macromolecules are made up of elements each with it's unique chemical bonds.
Within the cell, macromolecules are found in organelles ,which form the cells.the cells combines into tissues,which combines into organs .organs systems consists of similar functional organs.
living things commonly contains carbon, hydrogen, nitrogen,oxygen, phosphorus and sulphur.
(Mnemonic---CHNOPS)
Most plants grow from seeds. These seed plants fall into two groups, <u>angiosperms</u> and <u>gymnosperms</u>.
hope this helps ^^
Answer:
The polarity of membrane phospholipids
Explanation:
The inner core of membranes is made of nonpolar tails of phospholipids which in turn makes the membranes impermeable for polar, large and charged substances since these substances cannot cross the non-polar inner core. The saturated hydrocarbon tails pack tightly and make membrane less permeable while cholesterol affects the membrane permeability by interacting with non-polar tails.
Higher temperatures make the membrane more fluid and more permeable while at lower temperatures, membranes are more rigid due to tight packing of hydrocarbon tails and less permeable. The polar heads of phospholipids make the inner and outer surface of the membrane. Therefore, the polarity of phospholipids does not affect the membrane permeability.
The answer is 1.2 m³
1 L = 1 dm³
1,200 L = 1,200 dm³
1 dm³ = 0.001 m³
1,200 dm³ = 1,200 * 0.001 m³ = 1.2 m³
