B) Gene therapy involves replacing faulty genes with normal working genes in order to provide a cure for a genetic disorder.
Answer:
The endocrine system produces hormones that are transported to the target regions by the circulatory system.
The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.

Answer: Solar panels are made up of silicon cells. This because silicon has high ability for conduction and this make it to be able to convert sunlight into electricity. It is in solar cells has impurities and great chemical properties which make it to be to convert sunlight to electricity.
Silicon
Explanation:
Silicon is an element with atomic number 14, it is a non metal and crystalline solid. It has blue grey metallic lustre. Silicon is made with impurities in solar cells and has special chemical properties to convert sunlight into electricity. It is a semiconductor, a material that can act as a conductor and insulator.
When light interact with silicon cells, it make electrons to be in motion and initiate the flow of electricity, it is called photovoltaic effect.
Silicon alone is not used, it used with metal casing and wiring to ensure proper electric flow.
Bio-Engineering is the use of living vegetation, either alone or in conjunction with civil engineering structures and non-living plant material, to reduce shallow-seated instability and erosion.
<u>Explanation:</u>
DEVELOPMENT OF BIO-ENGINEERING:
In Germany and Austria wishes to use the low-cost local materials and traditional constructions due to their Financial restrictions of pre-war years 1930's
ADVANTAGES OF BIO-ENGINEERING:
Re-establishing vegetation and store the hydrology from the surface to control of accelerated erosion.
Cost-effective treatments:
- landslides
- Roadside failures
- River stream banks
- mining reclamation.
EXAMPLE:
GRASS PLANTING
Usually planting the large grass clumps in lines across the slope.
Horizontal lines are used to increase the protection against erosion.
