Explanation:
The cells store glycogen and neutralize toxins and are present in coelomic fluid of some annelids. They are yellowish in colour due to the presence of yellow granules called chloragosomes.
These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.
Answer:
Tertiary.
Explanation:
Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.
Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.
The only part of the two answers that is correct it the second part of answer A) which says “Release enzymes that digest cells.”
The other answers are not correct because...
*Fungi CAN be single and multicellular organisms.
*Fungi doesn’t have chlorophyll there for it doesn’t have the ability to do photosynthesis.
