Answer:
Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.

Answer:
Chloroplasts are able to capture sunlight using molecules called pigments. The function of a pigment is to absorb energy from light. Pigments are colored. … They contain the pigment called chlorophyll.
Explanation:
The TRUE statements are 'proteins often have more than one transmembrane domain'; 'they are regions of a transmembrane protein that actually pass through the lipid bilayer' and 'they are usually shaped like alpha-helices'.
A transmembrane domain is a membrane-spanning region within a protein. The transmembrane domains are hydrophobic regions that can be inserted into the cell membrane.
The transmembrane domains are usually shaped like alpha-helices.
This secondary structure (alpha-helices) causes the amino acid R-groups to project radially, thereby these side chains can interact with each other.
Proteins need only a single transmembrane domain to be anchored to the membrane, but they often have more than one.
For example, Acyl-coenzyme A cholesterol acyltransferases 1 and 2 (ACAT1 and ACAT2) have multiple transmembrane domains.
The transmembrane domains are regions of a transmembrane protein that actually pass through the lipid bilayer.
These domains contain amino acids with hydrophobic R-groups that pass through the membrane and interact with the hydrophobic tails of the fatty acid chains present in the lipid bilayer.
The transmembrane domains anchor transmembrane proteins to the lipid bilayer.
The interactions between amino acids of the transmembrane domains and fatty acids in the lipid bilayer help to anchor transmembrane proteins and stabilize the cell membrane.

Osmosis of Water Across the Membrane. Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. ... The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis
Answer:
The equation to this question is unclear. The clear equation is:
CH4 + 2O2 → CO2 + 2H2O
Please find the number of atoms of each element on the reactant and product side below.
Explanation:
An atom is the smallest indivisible part of an element. The atom retains the chemical properties of the chemical element. In order to ensure that a chemical reaction between molecules and compounds is BALANCED, the number of atoms of each element that makes up the molecule/compound must be the same on both the reactants and products side.
In this case, the chemical reaction involves:
CH4 + 2O2 → CO2 + 2H2O
1. Carbon atom (C):
Reactants side = 1 atom
Products side = 1 atom
2. Oxygen atom (O):
Reactants side = 4 atoms
Products side = 4 atoms
3. Hydrogen atom (H):
Reactants side = 4 atoms
Products side = 4 atoms
