True
Lysosomes are
organelles enclosed at the membrane, they contain series of enzymes that digest
or breakdown all types of biological polymers such as lipids, protein, nucleic
acid and carbohydrates. Also, lysosomes function as the digestive system of the
cell by degrading materials taken up from outside the cell.
Answer:
In science, this is false. Powers of ten are the references to either scientific notations or measurements when comparing atoms in chemistry.
I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.
Answer:
All the given choices
Explanation:
Carbon is a very interesting element which is the backbone of most organic compounds.
Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;
- An atom of carbon has 4 valence electrons and can bond with 4 other carbon.
- Carbon can form single, double and triple covalent bonds.
- They can join together to form rings or chains.
The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent
.
Answer: Option A
<u>Explanation:</u>
Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.
It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent. Separation and mixing up with solvent particles, in general, called as solvatation.
