Here, Amplitude mainly describes the intensity of sound we hear, They are directly proportional to each other. In other words, If Amplitude of the sound in greater, then you'll hear loud sound, vice-versa.
Frequency is the pitch of a sound. Change in frequency will change the pitch, and particularly for intensity, it doesn't affect loudness of the sound
Hope this helps!
What exactly is the question here
Answer: The answer is option B. Cell Walls
Explanation: Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. In eukaryotes, vertebrates don't have a cell wall but plants do.
Answer:
a plant can be categorized as a weed if it is growing where it is not wanted/needed
Answer:
d. Populations have the potential to grow to very large numbers
Explanation:
Natural selection and artificial selection both cause changes in animals and plants. However, the natural selection happens naturally, but selective breeding (artificial selection) only occurs by humans interventions. Natural selection has four components:
- Variation.
- Inheritance.
- High rate of population growth. In artificial selection, selection itself diminishes the probability of adaptation. But in natural selection populations have more offspring and have more chance to alive in struggling for local resources.
- Differential survival and reproduction.
