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.
The answer is the second choice
Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).
