1. The right side of the mammalian heart pumps blood to the LUNGS. Here it absorbs OXYGEN and is now called OXYGENATED blood.
The gas, CARBON DIOXIDE is removed from the blood in the lungs. The blood returns to the LEFT side of the heart and from here it is pumped to the BODY TISSUES where it gives up its OXYGEN and is now called DEOXYGENATED blood. It passes back to the LEFT side of the heart in VEINS
2. Single Circulation -> The blood only passes through the heart once
Double Circulation -> The blood passes through the heart twice
3. Made of myocardium (thick muscle), four-chambered separated by valves, cardiac muscle is oxygenated via cornary ateries + veins, transports blood carrying oxygen + nutrients to the body's tissues
The cell membrane maintains homoeostasis in the body which is the process by which cell maintains a fairly constant environment.
<h3>What is the cell membrane?</h3>
The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.
The correct graphical chart is as follows:
- cell membrane maintains homeostasis
- active transport requires energy
- passive transport does not require energy
- Diffusion occurs either through osmosis or facilitated diffusion
- facilitated diffusion occurs through protein channels
- Osmosis involves movement of water
- Endocytosis is the process the cell takes in substances into its inner compartment
- Exocytosis is the process the cell takes in substances into its inner compartment
- Pinocytosis is cell drinking
- Phagocytosis is cell eating
Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.

Dna is linked to all body functions because it is the genetic material which contains all the genetic information about our whole body.

In animals, a gene is inserted into an embryo, modifying the genome to manufacture the product of this new gene. In plants, a gene is injected into a single cell that is grown from a seed into a plant. This plant expresses the new gene in all its cells. The difference between GM and selective breeding.
They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
