A cell that consists of 3 types the cell membrane,the nucleus,and between the two,the cytoplasm within the cytoplasm lie intricate arrangements of fine fibers.
Answer:
identify the variables
Explanation:
control:type of lemon used
dependent:whether apple slice turns brown at pH>2
independent:pH value
The function of the central vacuole is to maintain proper pressure within the plant cells to provide structure and support of the growing plant.
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.
