The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level. What happens to the other 90%?
What is lost as heat?

1. Different finch species have beaks of different shapes and sizes. What do these beak differences tell us?
- Differences in beak shapes tell us that all the finches eat the same type of food.
- Different finch beak shapes are evidence that all Galápagos finches shared a common ancestor a long time ago.
- Different finch beak shapes are evidence that over time, finch species adapted to different food sources on the islands.
- Different finch beak shapes are evidence that several finch species with different beak shapes came to the Galápagos Islands from the mainland.

Placing wilted lettuce in cold water will make it crisp again. Which statement best describes what happens to restore the lettuce to its original condition?
A. Water left the lettuce cells by diffusion.
B. Water entered the cells of the lettuce by osmosis.
C. Osmosis caused salts to enter the lettuce cells.
D. Salts in the leaf caused water to leave the cells.
What is B-Water entered the cells of the lettuce by osmosis.

Scientist studied the presence of a disease in two different plant populations. One population reproduces sexually while the other reproduces asexually.
Why is there a larger number of infected plants in the asexually reproducing population compared to the sexually reproducing plant population?
a. offspring of sexually reproducing plants are identical to parent population
b. offspring of asexually reproducing plants are identical to the parent population
c. offspring of sexually reproducing plants have greater variation
d. c. offspring of asexually reproducing plants have greater variation
What is B

The evolution of the peppered moth is an evolutionary instance of directional color change in the moth population as a consequence of air pollution during the Industrial Revolution.
The frequency of dark-colored moths increased at that time, an example of industrial melanism.
Later, when pollution was reduced, the light-colored form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution.
The studies of changes between black and light color in populations of the peppered moth show that
a. natural selection can quickly change allele frequencies and common phenotypes in a population
b. species can always adapt to environmental changes
c. predators prefer light colored moths because they taste better
d. dark colored moths are physiologically superior to light colored moths
e. natural selection produces irreversible changes

A. Plant grown in a closed container in the sunlight
B. Plant in open container in a dark room but still receives water
C. Plant outside with natural rain
D. Plant grown under green light
What is C
(Factors that affect plant growth are light intensity, temperature, carbon dioxide concentration)

There has been multiple occurrences of marine organisms dying as a result of the ocean being littered with plastic. A group of college students decide to make a machine that can be placed in the ocean and collect garbage.
2 disadvantages (limitations) of the usage of this machine
Disadvantages: Harm to marine life, cost effectiveness, more plastic on land, temporary fix because people are still littering

There are 2 different species of spiders that both have different colors. One spider is brown and the other is a bright green. One can assume
A. Both spiders live in the same niche
B. the colors are adaptations fit to their environment
C. The different colors are used for mating
D. The green spider will eventually become extinct due to its bright color

B. The amount of carbon dioxide in the atmosphere will decrease.
C. The amount of carbon dioxide used by producers will increase.

Which of the following provides evidence that genetic variation is natural?
A. Crossing Over
B. Asexual reproduction
C. genetically modified organisms
D. Sexual reproduction
What is A- crossing over
Crossing over accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
