Answer:
C
Explanation:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
Answer:
option B
Explanation:
The bacteria cell walls is made up of mainly peptidoglycans. Archae is made up e.g pseudo-peptidogycans and others instead of peptidoglycans and eukarya are made up of many more substances other than peptidoglycans. Archae are also unicellular. Some groups of archae can survive at this temperature too. Thus what differentiates this organism from eukarya and archae is that its cell wall is made primarily of peptidoglycans.
90% of the energy is lost to the environment as heat and only 10% is transferred per trophic level
Answer:
NH2 group combines with COOH group to form CONH group after releasing water
Explanation:
A peptide bond is formed between two R groups of amino acids by eliminating a molecule of water. If two amino acid joins, then a dipeptide link is formed. When three amino acid joins, then a tripeptide link is formed. And in case when many amino acid joins, then a polypeptide link is formed. A protein chain usually has several amino acid residues ranging from 50 to 2000 in numbers. Since a polypeptide chain is formed after the removal of water , it is known as amino acid residues.
Generally , NH2 group combines with COOH group to form CONH group after releasing water
