1.Human interaction and coordination
Interaction
- Essential for survival
- Internal/external stimuli
Changes in the environment affecting the body
- Sensory receptors
Receive stimuli
Some of them found in sense organs
- The nervous system (neurons)
Information processor
Receives information from sensory receptors and initiates the appropriate response, coordinating and integrating all the cell functions
- Effector organs
Endocrine system
- Endocrine glands
- Hormones
Musculoskeletal system
- Muscles and bones
- Movement

Scope of aquarium: the art and technique of ornamental fish breeding and trade has a tremendous scope as a cottage industry
*Firstly it requires very small investment only a couple of thousands rupees initially
*Later the money automatically gets generated by the sale of fish and aquarium accessories
*Thus the further expansion of business does not require funding through loans
*The whole setup could be accommodated in the backyard of the cottage
*The amount of water required is also not very much

air masses
AIR CIRCULATION:
- Warm air expands (density decreases) and rises up leaving an area of low pressure.
- When air goes up through upper layers of the atmosphere cools down (se enfria).
- Cold air contracts going down into the atmosphere, generating a high-pressure area.
- From high pressure area, air flows near Earth’s surface to low pressures, warming up.
- The circuit which air flows continuously: convective cell.
- If Earth were motionless, air circulation would follow convective cells that would extend

Lipids: are organic molecules that are insoluble in wáter, with an oily, waxy or fatty consistency, whose functions are to store energy energy, to participate in muscule contraction, as insulators, and make up part of the cell membranes.there are three kinds of lipids: 1.fatty acids and waxes: that are only made up of carbon, hydrogen, and oxygen.2.´phospholipids: that also contain phosphorus and nitrogen. 3steroids: that are characterized by being made up of fused carbon rings. Fats: which are

Biological Organization of Plants
Cells: Basic units of life in plants with unique features like cell wall, chloroplasts, and large central vacuole.
Tissues: Plant cells form dermal, ground, and vascular tissues for protection, support, photosynthesis, and transport.
Organs: Roots anchor, absorb water and nutrients. Stems support and transport. Leaves perform photosynthesis and gas exchange.
Organ Systems: Shoot system (stems, leaves, flowers) for photosynthesis, reproduction, and support. Root system
