A species of moth lived in a forest with a mixture of dark- and light-colored trees. The coloring of these moths is inherited. The dark moths were hidden from predators on the dark trees, and the light moths were hidden on the light trees.
When the light-colored trees were killed by a disease, the forest was suddenly made up almost entirely of dark trees. Generations later, almost all the moths had the dark coloring. Which of the following gives a correct explanation?
Answer: The light moths that survived did not mate and have offspring because they thought that their offspring would easily be seen and eaten by predators.
The light moths that survived had dark offspring because the change in the environment caused the parents to decide to have offspring that would do better in the changed environment.
The light moths saw that the dark moths were less likely to be eaten by predators, so they made themselves dark as well.
The dark moths were better hidden from predators, so more of them survived. Because dark parents outnumbered light parents, there were many more dark offspring than light offspring in the next generation.

B.) The Exosphere
C.) The Mesosphere
D.) The troposphere
Answer: d
Explanation: The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.

Match each step in the nitrogen cycle to its description.
bacteria break down waste

bacteria convert ammonia
to nitrites and nitrates

nitrogen to ammonia
denitrification
arrowBoth
nitrification
arrowBoth
nitrogen fixation
arrowBoth
ammonification
arrowBoth
assimilation
arrowBoth
Answer:
Denitrification = bacteria convert nitrates into nitrogen gas.
Denitrification occurs when nitrogen is removed from the soil and this happens when bacteria concert nitrites back to Nitrogen gas.
Nitrification = Bacteria convert ammonia to nitrites and nitrates.
Nitrification is the process by which bacteria concert ammonia made from ammonification into useful organic compounds like nitrites.
Nitrogen fixation = bacteria break down waste products and return nitrogen to the soil.
Nitrogen fixation is when bacteria return nitrogen to the soil by breaking down waste products that fall into the soil.
Ammonification = bacteria convert atmospheric nitrogen to ammonia.
During ammonification, bacteria converts nitrogen compounds to Ammonia or Ammonium.
Assimilation = Plants and animals take in and use nitrogen compounds.
Assimilation then occurs when plants take in these nitrogen compounds and use them. Animals will get these compounds by eating the plants.

What is Invasive species?Invasive species can undermine an ecosystem's natural resources and put human usage of those resources in danger.
Aquaculture species can be released intentionally or accidentally, as well as through aquarium specimens or bait, oceangoing ships' ballast water, aquarium specimens, and other methods.
Invasive species have the potential to wipe out native species, reduce biodiversity, compete with native organisms for scarce resources, and modify environments. This may have significant negative economic effects and fundamentally alter the ecosystems of the Great Lakes and the seashore.
Therefore, The answer is the enviorment changes or an invasive spices comes into the area.

Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.
compare the similarities and differences between use of light as a development signal versus use of light during photosynthesis in plants.
