Which of the following statements is true about passive transport?
user100 [1]

Answer:

No cellular energy is needed in the Passive transport.

Explanation:

A movement of atomic molecules and ions throughout the cell membrane is known as passive transport. In this transportation of molecules no cellular energy is used.

As this movement is influenced by the tendency to grow as entropy, the energy is not in need unlike the active transport. Its rate depends on the permeability of cell membrane. There are four types of passive transport- facilitated diffusion, simple diffusion osmosis or filtration.

Water has special characteristics because of the nature of hydrogen bonds what are they?
Amanda [17]

Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water​.

Answer: Option A & D

<u>Explanation:</u>

A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.  

When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
