The alteration in the protein structures can take place due to many reason. Once, the structure of the protein is altered, it cannot perform its function, as it cannot bind to the site for which it is designated.
Most of the biological processes use proteins in their completion. In case, the protein cannot perform its function, the metabolic process associated with that particular protein may stop and cause severe illness.
The heat can cause the denaturation of the proteins. The proteins are made up of amino acid sequences, the heat can break the peptide bond present between the amino acids present in protein, which can result in alteration of protein.
Hence, the correct answer is option (d). all of them are correct.
Answer:
The options are
A) they may affect several populations in an ecosystem
B) they cannot be caused by human activity
C) they affect food chains but not food webs
D) They have no effect on living organisms in an ecosystem him
The answer is A) they may affect several populations in an ecosystem
Explanation:
Environmental changes include deforestation and climate changes. Organisms depend on their habitat and climatic conditions for their survival because it determines their food availability too.
When environmental change occurs they may affect several populations in an ecosystem.

Answer:
The enveloped viruses are resistant to disinfectants.
Explanation:
The outer covering or the envelope in the virus comes from the infected cell. This envelope is formed by the process called as budding off, from the host cell. The envelope that covers the virus provides resistance to various disinfectants and prevent virus from damage. The outer coat (envelope) is formed of a small part of cell membrane.
The virus that lyses and kills the cell immediately is less worse than the enveloped virus. The virus that kills cells immediately prevents the host cell from continuously synthesizing new virus particles. Thus, no more viral particles can be produced by the host cell. So, envelope viruses are worse that viruses that directly kills the host cell.
