The adaptations and natural selection will explain the changes because due to certain limited and available foods the diet of the birds change.

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.

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.
