Where does the energy stored in fossil fuels come from?
sedimentary rocks are mined and processed to make it
stored solar energy in phytoplankton, zooplankton, and other organic material
the stored energy in fossils
petroleum and natural gas
Answer:
stored solar energy in phytoplankton, zooplankton, and other organic material
Explanation:
The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.
In very early attempts to classify organisms, the greek philosopher, Aristotle, identified all animals as "aire dwellers, land dwellers, or water dwellers". Under this system, all of the following organisms would have been placed in the same group: bat, grasshopper, eagle, butterfly, flying squirrel, and sparrow. In the space below, construct a dichotomous key that can be used to identify 6 animals.

What is the water cycle? Describe what happens.
Answer:
Evaporation, Condensation, Precipitation, Surface Runoff
Explanation:
Evaporation: Water turns into gas and goes into the clouds.
Condensation: Water vapor in the air is changed into liquid water.
Precipitation: Water leaves the cloud as rain, hail, or snow.
Surface Runoff: Water left on land after it rains.

Why is gold so valuable? Is it found all over the world?
Answer:
"It turns out then, that the reason gold is precious is precisely that it is so chemically uninteresting. Gold's relative inertness means you can create an elaborate golden jaguar and be confident that 1,000 years later it can be found in a museum display case in central London, still in pristine condition."

Some species can reproduce sexually or asexually. In which two situations is sexual reproduction advantageous?
A. When no individuals of the same species are available for mating
B. When many individuals of the same species are available for
mating.
C. When the individuals live in a stable environment in which they
thrive.
D. When the individuals live in an environment that suddenly
changes.
Hey love! <3
Answer:
The two correct answers to this question are C. When the individuals live in a stable environment in which they thrive and D. When the individuals live in an environment that suddenly changes.
Explanation:
For species to adapt to their environments their youth must evolve and make changes. In a situation where two parents engage in sexual reproduction their child with have unique adapted traits from the two hosts while asexual reproduction creates a new organism identical to the host, making it useless in a changing environment.

What happens to the trait when proteins connect in different ways?
Which three types of pathogens cause disease by trying to get nutrients from
your body?
Answer: The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.
Explanation: hope this helps so the answer is A

Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while another was exposed to high light. The table provided shows the results of this experiment. Notice that more oxygen was produced by the Anacharis in high light.
Based on the information provided, what is the difference in volume (in mL) of oxygen produced between the low light and high light plants after 45 minutes? Record your answer below
Answer value
Answer:
Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium Light.
Explanation:
The increased light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
or Carbon dioxide + water = energy (glucose) + oxygen
Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:
carbon dioxide concentration
water availability
ambient temperature
light intensity;

List the differences between the hearts of vertebrates that live in water and the hearts of vertebrates that live on land. List the similarities.
Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.
