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.

Answer:
D
Explanation:
When imaging the joint by the use of traditional musculoskeletal imaging technique, long axis view shall be obtained of the joint under consideration, and the bones that are proximal to the joint under consideration should be kept on the left side of the screen, and the bone which is distal to the joint whose imaging is being done should be kept on the right side of screen. This is a way to get a clear image of desired joint.
Answer:
The population varies
Explanation:
The number of the dorminat alleles varies with the genotyoe. In addition, the factors as mutation also contribute to the mutation of the genes. The mutation in the DNA causes a different set of instruction in the DNA. This then affects the gene expression in an organism.
