Answer:
This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.

What happens to light energy when it is absorbed by a leaf?
Explanation:
In photosynthesis, chlorophyll absorbs energy to transform carbon dioxide and water into carbohydrates and oxygen. This is the process that converts solar energy to a form that can be utilized by plants, and by the animals that eat them, to form the foundation of the food chain.
Hope it will help :)

What group of organisms is found at the base of every energy
pyramid?
Answer:
Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

Question: Ignoring the human actions of auto and factory mission what generalization can you make about the balance of carbon dioxide and water to a real long period of time?
(Zoom into the photo of necessary)
Answer:
yes we can
Explanation:
Plants and Animals maintain a balance of CO2. Plants take in CO2 by photosynthesis and animals release CO2 by respiration.
Which is an example of carbon accumulating in the geosphere?
Select one:
Formation of fossil fuels from remains of dead organisms.
Breaking down the body of a dead organism and producing carbon dioxide gas.
Formation of glucose in plants through photosynthesis.
Breaking down glucose in cells through cellular respiration.
HELP NEEDED!! :(
Answer:
your answer is a
Explanation:
Carbon enters the geosphere through the biosphere when dead organic matter (such as peat or marine algae) becomes incorporated into fossil fuels like coal and organic-matter-rich oil and gas source rocks, and when shells of calcium carbonate become limestone through the process of sedimentation briefly described above. formation of fossil fuels form remains of dead organisms .

A company manufactures a chemical which acts as a strong chemical solvent. The chemical has a negative impact on the environment and human health when non properly disposed of. In order to be in compliance with the cradle to grave' tracking expectations of the federal government, the company must most clearly understand and abide by which law to track the manufacture and disposal of this chemical? A) Clean Air Act B) Clean Water Act Safe Drinking Water Act D) Resource Conservation and Recovery Act
Answer:
D) Resource Conservation and Recovery Act
Explanation:
The Resource Conservation and Recovery Act of 1976 was passed to ensure that the processes involved from the generation to the disposal of hazardous wastes are properly managed and meet up to health and environmental standards. The cradle represents the generation of the wastes while the grave represents the disposal of the wastes.
The company generating the hazardous waste is also responsible for other processes such as the transportation, treatment and storage of the waste.
neurons are activated by which of the following?
Answer:
Myelin sheaths protect, electrically insulate fibers and increase the speed of transmission of nerve impulses. What structural and functional type of neuron is activated first when you burn your finger? Unipolar (psuedounipolar) neurons that are sensory (afferent) neurons.
Answer:
A neuron is activated by other neurons to which it is connected. In turn, its own activation stimulates other connected neurons to activation

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
cloning is more controversial than cloning because it involves copying an entire organism

Rock layers showing ripple marks cross-bedding and fossil shells indicate that these layers were formed
a.) From solidification of molten material.
b.) From deposits left by a continental ice sheet.
c.) By high temperature and pressure
d.) By deposition of sediments in a shallow area
Answer:
d) By deposition of sediments in a shallow area
Explanation:
Deposition is the deposition of wind, water or ice sediments. The sediment may be shipped in the form of steaks, sand & mud or water-dissolved salts.
Sediment accumulation can be seen everywhere in the water chain, from ponds, reservoirs, deltas and floodplains to high mountain rivers.
Imagine there was no tilt to the earths axis and earths orbit was circular
Answer:
If the Earth was not tilted on its axis, there would be no seasons. And humanity would suffer.
Explanation:
When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.

Material produced from living or recently living plants or animals and their metabolic byproduct is?
A) charcoal
B) biofuel
C) biomass
D) MSW
Answer:
C) biomass
Explanation:
Biomass is sustainable, and is created from creatures such as plants and animals that come from live life. Plants, wood and waste are the most common biomass materials for electricity.
They are known as feedstocks for biomass. Biomass power also can be an electricity source that is not green. Bioenergy is biomass energy or biofuel energy.
