Answer:
Conjugation differ from reproduction because Conjugation transfer DNA horizontally to cells in the same generation.
Explanation:
Conjugation is a process of transfer of genetic material from one organism to another organism to direct contact.
An organism serve as the donor and transfer to another organism which is the receiver.
The donor carry DNA sequence called fertility factor. It transfer DNA horizontally to cells in the same generation. It is a type of genetic recombination that occur between two organisms.
Conjugation normally occur in bacteria.
Answer:
The atom has more electrons than protons.
Explanation:
Ions may be defined as the element that contains either positive or negative charge over it. Two types of ions are cations and the anions. The charge on the species is obtained by the loss or gain of electron.
Anions carry negative charge over them. Negative charge occurs by gaining of the electrons from its neighboring atoms. The number of protons and electrons are equal in neutral atom. Since, the ions gain the electron and hence it carries more protons.
Thus, the correct answer is option (a).
Answer:
Sharks, in their basal form have been on Earth for hundreds of millions of years. They were the first to develop a stream-like, torpedo shaped body and created a niche for themselves. Their aerodynamic body shape has evolved to allow for efficient and dynamic movement in water. Having a cartilage instead of bones allowed them to grow large and still be relatively light and buoyant . After they've evolved flexible, protruding jaws, there wasn't much to change. They were able to adapt and exploit all the water habitats as the world was changing.
Explanation:
Answer:
Stalagmites and stalactites are some of the best known cave formations. They are icicle-shaped deposits that form when water dissolves overlying limestone then re-deposits calcium carbonate along the ceilings or floors of underlying caves.
Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya.
