1.which of the following is a renewable resource? (A.wind) B.fossil fuels C.minerals D.land
2.The goal of -----is to use cells and tissues to treat human illnesses or injuries. A.clone (B.therapeutic cloning) C.reproductive D.gene therapy
Both are right now.
To determine which of the options is a renewable resource, we need to understand what a renewable resource is. A renewable resource is one that can be replenished or replaced naturally over time. Now, let's analyze the given options:
1. (A) Wind: Wind is a renewable resource as it is created by the movement of air, which is constantly replenished by natural processes. Answer: (A) Wind.
2. (B) Fossil fuels: Fossil fuels, such as coal, oil, and natural gas, are not renewable resources. They are formed from the remnants of ancient plants and animals and take millions of years to form. Once consumed, they cannot be naturally replenished in a short period of time. Answer: Not (B) Fossil fuels.
3. (C) Minerals: Minerals, including valuable resources like metals and gemstones, are not renewable resources. The extraction and depletion of minerals are generally irreversible processes. Answer: Not (C) Minerals.
4. (D) Land: Land is a more complex case as it can include renewable and non-renewable resources. However, the question asks specifically about a renewable resource, so land cannot be considered a direct answer. Answer: Not (D) Land.
To sum up, the renewable resource among the given options is (A) Wind.
Regarding the second question:
The goal of using cells and tissues to treat human illnesses or injuries is known as regenerative medicine. Among the answer options, (B) Therapeutic cloning aligns with this goal. Therapeutic cloning involves using cloning techniques to create embryonic stem cells that can be used for medical purposes, such as regenerating tissues or organs. Answer: (B) Therapeutic cloning.
