Answer:
In water hydrogen bonding formed between partially negative oxygen and partially positive hydrogen atoms.
Explanation:
Hydrogen bond is a partially electrostatic attraction between hydrogen (H), which is bonded to a more electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F), and another adjacent atom bearing a lone pair of electrons.
In water molecule hydrogen and oxygen have difference in electronegativity, due to which dipoles are form. One is partial positive on hydrogen atom and other is partial negative on oxygen atom. The electrostatic attraction occur between two oppositely charged poles which is known as hydrogen bonding.

d.damaging the environment
Answer:
c.reducing research cost
Explanation:
Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.
Research and testing on animals is contested as an ethical issue by animal rights activists.
Cloning living material is prohibited among some sections of society and is also being contested as an ethical issue.
Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.
