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.
A Safety Data Sheet refers to a detailed information document prepared by a manufacturer of hazardous chemicals. It describes the physical and chemical properties of the product.
<h3>What is
Safety Data Sheet?</h3>
- A Safety Data Sheet refers to a detailed information document prepared by a manufacturer or importer of hazardous chemicals.
- Describes the physical and chemical properties of the product.
- A safety data sheet provides comprehensive information about a chemical, including its properties physical, health, and environmental hazards; and protective measures or safety precautions to be followed in handling, storing, or transporting materials.
- Safety data sheets inform users about product hazards, how to use the product safely, what to expect if recommendations are not followed, how to recognize symptoms of exposure, and what to do in an emergency .
- Safety data sheets provide information about chemicals and help users of those chemicals to make risk assessments.
- They describe hazards arising from chemicals and provide information on handling, storage, and emergency procedures in the event of an accident.

Answer:
1: cell membrane
2. chloroplast
Explanation:
1. the cell membrane is the outer layer of an animal cell since they don't have cell walls

Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.
