Write a description or a reason why you are doing this activities of conserving our natural resources.
1. Using a glass when brushing teeth -
2. Hanging clothes -
3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

Give 2 ways in which the products of anaerobic respiration in yeast are useful to humans,

Anaerobic respiration in yeast (Saccharomyces cervisae) is also called alcoholic fermentation

Anaerobic respiration in yeast.
Anaerobic respiration is economically important - many of our foods are produced by microorganisms respiring anaerobically. Yeast is used to making alcoholic drinks. When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up.
How do humans benefit from the products of anaerobic respiration?Another advantage of anaerobic respiration is its speed. It produces ATP very quickly. For example, it lets your muscles get the energy they need for short bursts of intense activity (see figure below). Aerobic respiration, on the other hand, produces ATP more slowly.

Answer:
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.
Explanation:
Answer:
Viscosity is the resistance of a fluid to flow (thickness or thinness of a fluid). Fluids with high viscosity do not flow as easy as fluids with a low viscosity. Temperature affects viscosity, the warmer the liquid, the faster the particles flow and the colder it is the slower it flows. For gases when temperature increases, less friction occurs so it the flow rate is higher and when its col the opposite thing happens
