They are used to feel around and to capture prey. They extent their tentacles to capture prey, and use their nematocysts (nettle-like cells on their tentacles) to pierce and poison their prey. Hope that helps!
Joint capsule/ articular capsule is the sleeve-like structure encapsulates the synovial cavity and unites the articulating bones.
- The synovial cavity is filled with synovial fluid which helps to protect the cartilage and other connective tissue.
- The joint capsule/articular capsule is a thick fibrous connective tissue which forms a sleeve to enclose the synovial joint and synovial cavity.
- The joint capsule/articular capsule is a strong connective tissue continuous with the outer most layer of bone known as periosteum of articulating bones, enclosing the synovial joint and unites the articulating bone.

This is actually quite hard, took me a while.
Answer:
The correct answer is
1. 5' end.
2. guanosine
3. 5′ to 5′ triphosphate linkage.
4. On the 7th position.
5. 2′ hydroxy-groups of the first 2 ribose sugars.
Explanation:
The eukaryotic mRNA is processed or modified with a guanosine cap at 5' end and poly-A tail at 3'end before translation.
The process of adding a cap at 5' end of a growing mRNA is known as capping. The process of capping adds guanosine nucleotide at the 5'-end of mRNAs by 5′ to 5′ triphosphate linkage. This guanosine is modified by methylating at the 7th position of the atom. The mRNA is further modified by methylation of first two ribose sugars at their 2′ hydroxy-groups. This capping is advantageous to the sequence as it protects the end from phosphatases and nucleases.
