Answer: Cysteine residues are involved in disulfide bridges that helps to form tertiary structure in a protein
Explanation:
The tertiary structure of a protein will have a single polypeptide chain backbone with protein secondary structures. The interactions and bonds of the side chains within a protein determine its tertiary structure.
<u>The cysteine forms the disulfide bridges and they link the fragments within a polypeptide chain</u>. Sometimes those fragments are located very far from each other with respect to their primary structure. So, the tertiary structure is the three dimensional shape of a protein.
There are 5 levels of body organisation, which include, cell, tissue, organ, organ system and organism. The cells together make up the tissues; the tissues together make up the organs. The organs make up the organ system, and the organ system make up a complex organism.
The human stomach is made up of tissues. It is an organ. Arachnoidiscus ehrenbergi also shows an organ level organisation.
So, the correct answer is Organ.

Explanation:
prokaryotes are things like bacterial cells , they have no true nucleus just a long ring of dna.
Eukaryotes are things like animal cells they have a nucleus (opposite of prokaryotes)
Answer:
No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.
Explanation:
Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.
When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.
