Answer:
Reverse Osmosis.
Explanation:
This is the mechanisms of water purification for drinking water which is droven by the chenical potential of the solvent .
It involves the use of partiaiy permeable membrane to allow ions , water molecules ,solvent molecules to pass through during purification
A pertial permiable menenrane in this prurifiction process is the membrane that allow only water molecules, ions and restricted other unwanted chemical contaminants from passing through it.
Sunflowers grow on a large stalk, and often only produce one flower. paddy plants produce many small flowers, with heavy pollen.
Excessive calorie intake during pregnancy can result in a fetus that has high birth weight. Pregnant women have indeed higher energy requirements but only by 300 calories daily. Eating an excessive amount of calories daily during pregnancy can lead to an increased weight gain that can result in an increased birth weight. Excessive weight gain during pregnancy can also endanger the progression of the pregnancy and the delivery of the baby.
Explanation:
C. They make it more fluid
Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

It’s a false because there is different types of family structures like nuclear family structure family structure so it’s a false.
Hope this helps
