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.

The answer to 3 is B. Moon
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
