Hydrogen bonds or h bonds are between water molecules
A water molecule contains an oxygen atom and two hydrogen atoms which are covalently bonded to the oxygen atom.Atoms in a covalently bonded molecule are always fighting for the shared electrons, the atoms attraction to the shared electrons is called the electronegativity. Therefore, the more electronegative an atom is the more it attracts the shared electrons.The force of attraction between a partially electronegative atom and another partially positive atom is the hydrogen bond. It is the hydrogen bond that pulls water molecules together which results into a cohesive force between the water molecules.
Chlorophyll is a pigment found in the thylakoid membranes of the chloroplasts in the leaves. This is why plants are green. The simple answer is that plants are green because they have green chloroplasts.
Answer:
Active transport; Passive transport; Passive transport
Explanation:
When concentration of a substance is different on either side of a semi-permeable membrane, the movement of this substance can occur by active or passive transport. Active transport occurs when the substance is moved from the region of its lower concentration to that of its higher concentration. This type of movement uses the energy to move the substance. Since the glucose concentration is higher in the epithelial cells than in the food, it will enter into the cells by the process of active transport.
The passive movement of substances is driven by concentration gradient. The glucose concentration is lower in extracellular space than epithelial cells, so glucose will be transported into the extracellular space by passive movement.
Likewise, a higher concentration of glucose in extracellular space than blood will move it passively into the bloodstream.
Yes coz it has all compont of cell like nucleus and others
