Answer:
Option D, the "biological ladder"
Explanation:
The food chain is the network of organism in which all are dependent on each other for their food, energy source and survival.
The circle of life depicts the time frame starting from origin of a life form till its death and the intermediate stages.
The tree of life basically determines which organism has evolved from which other organisms.
The biological ladder represents the development of species from simple form to a much complex form.
Hence, option D is the right metaphor
The correct answer is: Inserting a gene into a pea plant to make them resistant to insects
The receptor molecule is the ones which allow different interaction to occur between the matrix and the cell.
<u>Explanation:</u>
Receptor molecules are the protein molecules that have the ability to bind the signaling molecules at the surface of the cell in order to send signals to the matrix. Those signals on receipt<em> </em>act as the channel of communication.
Thereby, the interaction between the cell and matrix is established. Usually, this is one of the kinds of interaction. Paracrine interactions are interaction within adjacent cells whereas the endocrine interactions are interaction with distant cells.
Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
<h3>What are Biodiversity hotspots?</h3>
Biodiversity hotspots may be defined as the regions of the earth which are rich in biodiversity and possesses the following criteria:
- The area should support greater than 1500 endemic species of flowering plants or 0.5% of total plants.
- It possesses a high degree of threat, exploitation, and biodiversity.
- It must have lost about 70% of the original habitat.
- A high degree of endemism (restricted habitat).
Therefore, Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
