Answer:
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
Answer:
- production of vaccine for disease prevention
- production of genetically modified crops
Explanation:
Recombinant DNA is a special type of DNA that has been infused with a foreign gene of particular interest.
With recombinant DNA technology, scientists can study different proteins and see how they can be used for therapy in the area of medicine. <em>The technology has been used to produce several vaccine in the prevention of diseases.</em>
In addition, recombinant DNA technology has been useful in agriculture to produce <em>genetically modified crops with desired traits such as resistance to pests/diseases and high yields.</em>
Answer:
When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
Explanation:
one is adapted to live in a hot and dry environment and one is adapted to live in a humid environment.
Answer:
The correct answers are:
1. stratospheric ozone depletion
2. climate change
3. desertification/land degradation
4. freshwater decline
5. biodiversity loss.
Explanation:
1) Stratospheric ozone depletion- ozone layer is the protective layer around the earth that protects us from harmful rays such as UV rays coming from the sun. There are depletions or holes in the ozone layer in some parts of Australia and therefore, therefore leading to skin cancer.
2) climatic change - The change in the average temperature or precipitation of an area that takes place due to global warming that changes the earth's climate is changing rapidly.
3) desertification or land degradation - It occurs due to past overuse of fertilizer or barren land that has zero crop yield.
4 )freshwater decline - freshwater is an essential part of the irrigation of crops in agriculture and due to the downfall of groundwater its decline the freshwater produce in these parts.
5) biodiversity loss - Coral reefs are habitats for many aquatic organisms and used as various ways of biodiversity. If there is a loss or decrease in their numbers it will affect and decline the biodiversity of the area.
