Define, describe and give examples of Internal, External, and Behavioral adaptions.

Answer:

All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.

Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

birdFor example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.

Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.

Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.

The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

Saundra experimented with making solutions from water and a powdered drink mix. She measured the powder in tablespoons (T) and the water in milliliters (mL). She observed the color and taste of each solution and recorded her data in the table below.

Water (mL) Powder (T) Taste Color
100 mL 1 weak
100 mL 2 normal
100 mL 3 strong
100 mL 4 very strong

According to Saundra's table, how did she make her solution more concentrated?

Scenario:Fossils show that many species, or kinds of organisms, have died out or become extinct because they could not respond to the pressures fast enough to survive. Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time. Evidence shows that species change over time, sometimes giving rise to new species.External DataPrompt:Look at the pictures above that show how the giraffe got such a long neck. Write a scientific explanation of how natural selection applies to this process.

This is a star map of the constellation Orion. It represents part of the celestial sphere on a specific day, time, and location.

star chart depicting constellations. On the left side of the star map is the declination, ranging from -26⁰ at the bottom of the chart to 34⁰ at the top of the chart in increments of 2⁰. The right ascension begins at 7h and decreases hourly as you move to the right. The larger stars that comprise the constellation Orion are; Rigel with a declination between -10⁰ and 0⁰ and right ascension between 6h and 5h. Alnitak has a declination between -10⁰ and 0⁰ and a right ascension between 6h and 5h. Bellatrix has a declination between +10⁰ and 0⁰ and a right ascension between 6h and 5h. Betelgeuse has a declination between +10⁰ and 0⁰ and a right ascension between 6h and 5h
