Hybridization . 1. Occurs frequently in nature 2. Is the process of gene combination in a lab 3.Usually produces offspring that cannot reproduce 4.Creates genetically identical offspring

Option-3

Explanation:

Hybridisation is an artificial process which is performed by humans to form a product by the combination of genes.

The genes or trait of desire are selected from two different organisms as a result of which a new hybrid organism is formed which contains the selected traits of organisms. The hybridisation can also be termed as the selective breeding and was practised by the humans from 10,000 years ago.

Since the hybridisation produces the infertile offspring as it produced artificially therefore Option-3 is correct.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
