Poaching refers to the illegal hunting of wild animals in violation of the laws which regulate hunting of wild animals. Over utilization refers to the exploitation of an animal to the point of extinction. Poaching activities include hunting and killing wild animals without licence, using illegal weapons to kill animals, killing animal out of season, etc. All these activities can lead to drastic reduction in the population of animal specie to the extent that the animals become extinct. A good example of an over utilized animal specie is passenger pigeon.
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.
As the action potential passes through, potassium channels stay open a little bit longer, and continue to let positive ions exit the neuron. This means that the cell temporarily hyperpolarizes, or gets even more negative than its resting state.
Plants use energy from sunlight to turn water and carbon dioxide from what they get into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. In photosynthesis, the energy in light is absorbed by photopigments.
The density would be 14.567 lb/cu ft
