In which investigation would it be BEST to use observational data obtained outside of a laboratory rather than empirical data from controlled experiments?


an investigation to determine the amount of oxygen that an animal consumes while sleeping

an investigation to determine the genetic code of a harmful bacteria

an investigation to determine the structure of a protein

an investigation to determine the feeding habits of a species of bird

Answers

Answer 1

An investigation to determine the feeding habits of a species of bird

employs the use of observational data obtained outside of a laboratory.

Observational data outside of a laboratory is best suited for feeding habits

of a bird because it requires lower degree of control over the environment.

Feeding pattern doesn't require any special technique which is why it can be

done on the field.

Other options require the use of  higher degree of control over the

environment  to ensure accurate results are derived.

Compare the structures for genetics with every day objects. Must include the words: genes, DNA, chromosomes, and nucleus.

Answers

Answer:

Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.

What is an organ ?

An organ within an organism performs specific tasks to maintain the overall health and function of the organism. To accomplish these tasks, an organ typically requires interaction with other organ systems within the organism.

For example, the digestive system works in tandem with the circulatory system to transport nutrients to the cells, while the respiratory system works with the circulatory system to deliver oxygen to the body. By working together, the different organ systems help to maintain the overall health and function of the organism.
