Pathology is the branch of science that focuses on the causes, effects, and nature of diseases in organisms.

It studies both the structure and function of diseased tissues and organs.

Explanation

Cytosine does not form a bond with adenine because its hydrogen bond donors and acceptors are not complementary.

Cytosine typically forms three hydrogen bonds with guanine, whereas adenine forms two hydrogen bonds with thymine.

The patterns of hydrogen bonding in cytosine and adenine do not match, preventing the formation of a stable pair.

Explanation

Pollination in plants enables fertilization.

During this process, pollen from the male part of the flower reaches the female part.

This leads to the production of seeds.

Explanation

Singer and Nicolson proposed the Fluid Mosaic Model in 1972 to describe the flexible, dynamic structure of the cell membrane.

It shows proteins floating in a fluid layer of phospholipids, like a "mosaic."

Explanation

New cells arise from pre-existing cells through cell division (mitosis or meiosis), as stated in the cell theory.

Old cells do not form from division; they are the parent cells that divide.

Explanation

Uranium is a non-renewable energy source used in nuclear power plants for generating electricity through nuclear fission.

It is finite and cannot be replenished on a human timescale, unlike renewable energy sources such as solar or biomass.
