Answer:
The correct answer is -muscular system and skeletal system.
Explanation:
The skeletal system and the muscular system work together to move the body or body parts. Different types of tissues form the muscular system that and their action on bones controls the movement of the body in vertebrates.
Tendons are tough muscles that attach with the bones and joints allow the movement by contraction of muscle that helps in moving bones from joint. Muscle normally acts by contracting and relaxing in pairs.
Answer:
In Cytokinesis, the contractile ring in animal cells contracts and pinches the cell into 2 daughter cells. In plants, the phragmoplast extends and forms the cell wall. In plants, mitosis occurs only in the meristem tissues.

Answer:
Option A, helps prevent rapid breakdown of the messenger RNA
Explanation:
The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.
Hence, option A is correct
