Adaptations- Brainlist for all questions answered! 1. 3 examples of external adaptations (like structural)
2. 3 examples of internal adaptations (like structural)?
3. Describe what adaptations a plant may have. What is a stomata? What is xylem? What is a bulb?
4. What two parts make up a scientific name?

1-Caves to helps bears hibernate, trees to help birds sleep, and webbed feet to help duck

2-long necks of giraffes to helps eat form tall trees, the streamlined bodies of aquatic fish and mammals, the light bones of flying birds and mammals.

3- A adaptaiona plants may have are they are able to live in the water underground or on land, a pores in leafs and/or plants, vascular tissue in plants that has water and dissolved nutrients, and underground organ that some plants have.

4- the specimens of making a scientific name are the first part of the name is genus (plus the genus is always capitalized) and the second part of the scientific name is that is the species

Explanation: hope this is what u were looking for

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
