The three types of cloning are recombinant DNA technology (DNA cloning or gene cloning), reproductive cloning, and therapeutic cloning. A wide range of biological materials, such as genes, cells, and organisms have been cloned. Cloning has raised many ethical concerns.
There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:
1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:
a. Simple Diffusion:
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves.
b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.
c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.
2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.
The observation of the relationships between the anemone and clownfish supports the statement 'symbiotic relationships are important to an ecosystem' it is a fundamental ecological interaction.
<h3>What is symbiosis?</h3>
Symbiosis is a type of ecological interaction where both organisms are benefited from such interaction.
Symbiosis is a fundamental biological interaction that supports the delicate equilibrium (homeostasis) of both marine and terrestrial environments.
The relationships between the anemone and clownfish represent a piece of clear evidence that symbiosis not only helps these species but also the entire ecosystem.

Cause mammals are the only species that are well developed before birth unlike marsupial and monotremes
The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.
