How does a birds beak help you identify its habitat
Rasek [7]
A birds beak helps you identify its habitat by looking at its size and shape. The size and shape will give you an idea of what type of food it eats. A bird will have a beak that is suited for eating food that they find in their habitats such as seeds, nectar, insects, mice or fish. For example, pelicans live close to the ocean. Their beaks are long and they have a pouch in their throat. They catch fish by gulping them out of the water into their throat pouch. If you ever been to Daytona Beach this is a familiar sight. Not something you would see sitting on a park bench in Central Park!  Hmmmm  <span>sighnoah</span> THANKS!

Describe the ways mutations can affect DNA and chromosomes.​
lozanna [386]
Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.
