The rabies virus spread through animals and cause deadly effects. The influenza virus is easily passed between humans and is easily treatable and much less deadly.
Oxygen production of plants different at different times of the day due to presence of sunlight.
In cellular respiration, oxygen is taken in and carbondioxide is releases in the environment whereas in photosynthesis, carbondioxide is taken inside and oxygen is releases in the atmosphere so in this way matter is conserved during the processes of photosynthesis and cellular respiration.
Oxygen production of plants different at different times of the day because oxygen only produced when there is photosynthesis process which only occurs in the presence of sunlight. If plant was placed in a completely dark environment then there is no oxygen is produced and no photosynthesis occur.

Answer:
A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
Electrical energy
Explanation:
Electrical energy is the energy created by the flow of electrons through conductors.
The movement of electrons in conductor generates electricity.
- Electronic movement in electrochemical cells also produces electrical energy.
- Current flows in opposite direction to the flow of electrons.
- The electromotive force of cell provides the driving force for the current in a cell.

Capillary action is possible due to COHESION property of water.
Capillary action is defined as the movement of water within the spaces of porous materials due to the forces of cohesion and adhesion. Cohesion refers to the tendency of water molecules to stay together while adhesion refers to tendency of the water molecules to be attracted to other substances. In plants, capillary action moves water and the nutrients dissolved in it from the roots of the plants to the leaves in the branches.
