To recognize and remove trigger foods
The four principles of natural selection are variation (organisms within a population have their own individual differences in their appearance, such as, markings and color), inheritance (traits passed down to the offspring), high rate of population growth (which leads to their local resources to be more of a challenge to find), and differential survival/ reproduction (organisms in the population with stronger traits are more likely to survive and reproduce, aka survival of the fittest). These four principles work together to respond to chance in the environment by making sure the strongest survive and over time that species will adapt to their environment because the organisms with the better suited traits will pass their traits to its offspring.
I hope that made sense, lol.
Answer:
b. 457 Hz
Explanation:
Things including sound move like waves in the air. The distance between the crest of those waves is known as the wavelength, denoted by lambda (λ).
The wavelength of a sound can be calculated using the formula: λ = c/f
Where; λ= wavelength
c = speed of sound
f = frequency of sound
According to the question;
Wavelength of sound (λ) = 0.750m
Speed of sound (c) =342.5m/s
To calculate frequency (f), we make f the subject of the formula in λ = c/f
We initially cross multipy to have; c = λf
Divide both sides by λ to have; f = c/λ
We then calculate by inputting our values into the formula: f = c/λ
f = 342.5/0.750
f= 456.66
Approximately, the value of the frequency of the sound is 457Hz.

Answer: In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.
