Question

write the words or phrases from the bank to complete the sentences. each word or phrase should be used exactly once. living organisms are made up of units called _1_ and they _2_ to generate offspring. the genetic code for living things is carried in _3_ which conveys instructions for _4_. living things obtain and use _5_, and respond to _6_ in their environment. they _7_ and maintain 8_ a stable internal environment. dna growth and development cells materials and energy homeostasis stimuli reproduce evolve when news of a scientific discovery is reported, readers must assess the credibility of the claim. in general, which statement indicates a valid and credible claim? (a) the scientist aimed for pinpoint accuracy by using a small sample size. the scientist followed strict standards of investigation and scientific methodology throughout the research. (d) no other scientists replicated the experiment to avoid the legal issues of patent infringement.

Explanation:

1. Living organisms are composed of cells.
2. Reproduction is the process to generate offspring.
3. DNA carries the genetic code.
4. DNA provides instructions for growth and development.
5. Organisms obtain and use materials and energy.
6. They respond to stimuli in the environment.
7. Organisms evolve over time.
8. Homeostasis is the maintenance of a stable internal environment.

For the multiple - choice part, following strict scientific standards and methodology ensures credibility. A small sample size is not good for accuracy, and lack of replication is not a sign of a valid claim.

Answer:

1. cells
2. reproduce
3. DNA
4. growth and development
5. materials and energy
6. stimuli
7. evolve
8. homeostasis

Multiple - choice: B. The scientist followed strict standards of investigation and scientific methodology throughout the research.
