Which of the following describes a way to reduce the activities that generate solid waste?
1. Compost food instead of throwing it in the garbage.
II. Buy reusable items that won't break easily.
III. Buy products made from new materials.
1. I only
2. II only
3. I and II
4. I, II, and III
Answer:
3:1 and 2.
Explanation:
Energy and nutrients from food that has been turned into compost can be used by plants to grow. Using reusable items that won't break easily prevents you from throwing it away cause what's the point. If it ain't broke why throw it away.
Activities that reduce solid waste are composting food instead of throwing it in the garbage. Hence, option C is correct.
How can solid waste be reduced?Solid waste can be reduced through various measures, some of which are:
Reduce, Reuse, and Recycle: The three Rs of waste reduction can help in reducing the amount of solid waste generated. By reducing the consumption of products, reusing items, and recycling materials, less waste is sent to landfills.
Composting: Organic waste such as food scraps, yard waste, and paper products can be composted to produce nutrient-rich soil for gardening.
Avoiding single-use items: Single-use items such as plastic bags, straws, and disposable cups can be avoided by using reusable alternatives.
Buying in bulk: Buying products in bulk can help reduce packaging waste.
Donating items: Items that are still in good condition but are no longer needed can be donated to local charities or thrift stores. Hence, option C is correct.

Which restriction endonucleases would cleave a dna molecule at the given sequences? the complementary dna substrate strand is omitted for clarity.
The types of restriction endonucleases that would cleave a DNA molecule at the given sequences are type I and type II restriction endonucleases.
What do you mean by Restriction endonucleases?Restriction endonucleases may be defined as a protein constructed by bacteria that cleaves DNA at specific sites along the molecule.
Among the type I and type II restriction endonucleases, type II restriction endonuclease cuts the DNA molecules more efficiently and is widely used for the same procedure as compared to type I restriction endonucleases.
Some of the examples of type II restriction endonucleases include EcoRI, HindIII, BamHI, etc.
