Katie will use the black, red and purple balls in a ratio 1:2:1 for carbohydrate molecules.
There are four macro molecules in existence, these are carbohydrates, proteins, fat and oil and nucleic acids. All these molecules has carbon in their compounds. The carbohydrate is made up of the elements carbon, hydrogen and oxygen in the ratio 1: 2: 1, thus, the molecular formula of carbohydrate is C6H12O6.
Answer:
d Divergent plate boundary
The type of boundary described as follows 1. Transform boundaries. 2. continental Convergent boundary. 3. oceanic convergent boundary.
<h3>What are the 3 types of plate boundaries ?</h3>
- Divergent boundaries -- where new crust is generated as the plates pull away from each other.
- Convergent boundaries -- where crust is destroyed as one plate dives under another.
- Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Hence, The type of boundary described in the given question are as follows 1. Transform boundaries. 2. continental Convergent boundary. 3. oceanic convergent boundary.

Answer:
A separation of a species or population so that they no longer interbreed and evolve into two separate species.They must mate with other species; the gene pools of two populations must become separated, or reproductively isolated.
Explanation:
Answer:
Gap junctions
Explanation:
They allow adjacent cells to communicate. These channels form a close connection between cytoplasm because small molecules such as ions are able to pass through from cell to cell. Examples of cells with gap junctions are cells in heart muscle tissues. Gap junctions are found in animal cells and are akin to plasmodesmata in plant.
