Answer:
The correct answer would be reproduction.
Single-celled organisms usually reproduce asexually with the help of cell division.
Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.
Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.
Unicellular organism usually divide by fission either binary or multiple.
In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.
In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.
Answer:
The type of locomotion that would benefit from having a high olecranon is suspensory (option A).
Explanation:
Olecranon is a bony prominence or process associated with the cube bone and is found at the elbow joint in the upper extremities.
The olecranon process blocks the extension of the elbow by fitting into the socket of the humerus bone, allowing the upper limb to be firm and stable for support on elevated surfaces, climbing, or suspensory locomotion.

Answer: Option D: Neuromuscular junction
Explanation:
This is the site of transmission of chemical signal also known as a chemical synapse between a neuron and a muscle fibre. Most of the time the chemical released which is a neurotransmitter is acetylcholine. When released, it stimulates the release of calcuim ions present in the sarcoplasm: an endoplasm like structure in the muscle fiber that contains calcium ions.
