To find the answers to these questions, you can start by using your knowledge and understanding of biology. Let's break it down step by step:

1. An idea that explains the characteristics of living things? (2 words, 10 letters)
In biology, the concept that explains the characteristic features of living things is called "Life Science" or "Biology." Both of these phrases are two words and have 10 letters. Therefore, either of these answers could fill in the blank.

2. Type of cell that helps an animal respond to its environment? (5 letters)
This question is asking for a type of cell that allows animals to respond to their environment. One of the key players in this process is the "nerve cell" or "neuron." Both of these options have five letters and would be suitable answers.

3. Plants have different types of cells for different _______? (5 letters)
The question is asking for a word with five letters that completes the sentence and refers to the purpose for which plants have different types of cells. The answer here would be "tasks." Plants have different types of cells to perform various tasks such as photosynthesis, storage, transport, and support.

Remember, when faced with such questions, it's helpful to draw on your knowledge of biology and the specific context provided.
