Explanation:
Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions. Waveforms of different types surround us at all times, however we only have receptors which are sensitive to specific types of wavelengths. In this section, we describe the physical properties of the waves as well as the perceptual experiences associated with them.AMPLITUDE AND WAVELENGTH
Two physical characteristics of a wave are amplitude and wavelength (figure below). The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.
The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.
Wavelength is directly related to the frequency of a given wave form. Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies
Microorganisms of a family of fungi, called the Lepiotaceae, live with leaf-cutter ants. The ants collect fresh leaves to grow the
fungus, and then they feed the fungus to their larvae. Another type of microorganism, a fungus of the Ophiocordyceps family, also
has a relationship with a type of ant. The spores of the fungus attaches to carpenter ants in order to complete its life cycle. The
spores spread into the ant's body and causes behavioral changes in the ant, eventually causing the ant's death.
What does this information demonstrate?
Answer:
Between the Lepiotaceael and the eaf-cutter ants, there is what we call mutualism. They both depend on each other buh no harm is done.
But between Ophiocordyceps family and the carpenter ants, it is called parasitic relationship. The Ophiocordyceps harms the carpenter ants.

Answer: Mutations can be good or bad.
Explanation:
Up until now, no characteristics or qualities have been assigned to the predators and prey. Suggest a trait of the prey and a trait of the predators that might account for the results of your model. How do the results of your model help explain the process of natural selection in a predator-prey relationship?
Answer:
Predator foraging traits include;
body size (mass or length), gape size, hunting or foraging mode (for example, ambush or active hunting), and feeding mode (for example, chewing or suctorial) .Prey vulnerability traits include;
body size (length and mass), body shape, defense (for example, physical or chemical protection), ability to avoid detection (crypsis or camouflage), mobility, ability to recognize and detect predators, and evasive or escape behavior (which can be elicited by physiological trait responses.But whether or not predators engage with prey, or prey respond to predators in the first place, depends fundamentally on their relative body sizes (or predator gape and prey body shape). Pursuing prey that are too large or cumbersome can be harmful or energetically costly to predators, and pursuing prey that are too small may not be worth the energetic return.
As these populations continue to reproduce over time, the actions of natural selection can also change the species to make them better predators, or more defensive prey. Either way, this adaptation changes the entire predator prey dynamic. If one species cannot then adapt an appropriate defense, they may go extinct.

*PLEASE ANSWER* How can someone live smarter to reduce his/her carbon footprint? a.) live in a smart community b.) buy inefficient appliances c.) use incandescent bulbs
Answer:
a.) live in a smart community
Explanation:
A standard incandescent light burns through 50 watts of electricity per hour. Replacing an incandescent bulb with an LED bulb can save 6 tons of household emissions per year. Saving 6 tons of carbon emissions is the same as reducing your gas consumption by 700 gallons. (proving b wrong)
you can help reduce your carbon footprint and other greenhouse gases by using energy-efficient home appliances since they have lower emissions of harmful gases into the environment. (proving c wrong)

Explanation:
Hyponatremia is a condition in which the sodium in the blood is too low. Uncontrolled spasms, which are sudden, involuntary contractions of muscles, are among the symptoms of hyponatremia. Why do they occur? A. Sodium is needed to generate an action potential. B. Sodium makes up most of the myelin sheath. C. Sodium is the signaling molecule that transmits impulses across a synapse. D. Sodium controls voluntary movement, and potassium controls involuntary movement. Reset Next
Answer:
A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

juan earn $11 per hour and works at most 30 hours per week. identify the independent and dependent quantity in the situation, and find reasonable domain and range values
Answer:
The hours are the independent variable.The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .The domain is 0 to 30 The range is 0 to 330Explanation:
The hours are the independent variable and should be plotted on the x-axis .
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
---------------
Let +W+ = wages/wk earned
Let +h+ = hours/wk worked
The equation is:
+W+=+11h+
The domain is 0 to 30
( no hrs worked to 30 hrs worked )
The range is 0 to 330
( no wages eared to +11%2A30+=+330+ earned )
What kind of cells can develop from unipotent stem cells?
Answer:
Unipotent stem cells are capable of differentiating into only one mature, terminally differentiated cell type. Spermatagonial stem cells are unipotent and only capable of developing into sperm cells.
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. How does the design of your experiment control for outside factors that may affect the results?
Answer:
yes the fertile soil will grow faster and taller
Explanation:
the fertile soil will grow faster because it has what the plant needs
