The Internal skeleton of the porcupine gives shape and structure to the porcupine.
The stem of the rose plant provides support to the plant and serves to transport nutrient and water in the plant.
<h3>What a skeleton?</h3>
A skeleton is a rigid structure found in living organisms which provide structure and shape to the living organism.
Skeletons are found in animals.
Skeletons present in animals are of two types:
- Internal skeletons also known as endoskeletons
- external skeletons also known as endoskeletons
The Internal skeleton of the porcupine gives shape and structure to the porcupine. It also serves as a point of attachment to muscles in order to enable movement.
Stems are present in plants.
Stems serve various purposes in plants such as:
- transport of nutrients and water
- storage of food and water
- provides support and structure to the plant.
Thus, the stem of the rose plant provides support to the plant and serves to transport nutrient and water in the plant.
In conclusion, the internal skeleton of animals and the stem of plants both provide shape and structure to the respective organisms.

Answer:
cytokinesis
Explanation:
cytokinesis is when the cell splits into two daughter cells.
<u>Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.</u>
Mitochondria is the part responsible for making the ATP for the cells.
Answer:
Dendrites, cell body, axon hillock, axon, synaptic terminals, biceps brachii.
Explanation:
Neurons are the structural and functional unit of the nervous system. The neurons helps in the transmission of nerve impulse in the body. Two main types of neuron are somatic neuron and motor neuron.
The signal is first reach to dendrites. From the dendrites, the signal transmit to the cell body and then to the axon hillock. The signal then transmits to the axon. At the end of neuron the message is transmitted to the synaptic terminal. The nerve impulse finally reaches to the biceps brachii and results in the flexion of the arm at the elbow.
