The smallest and most exclusive grouping category is species.
The correct answer is frequency.
The pitch can be defined as the quality of sound produced by the rate of vibration producing it.
It is directly related to the the frequency of the sound wave. If the frequency is increased then its pitch will also increase and vice versa.
As for normal people it is a bit difficult to differentiate between the two but the musician are trained so they can differentiate the difference between the two even if the difference is 2 Hz
Answer:
Microorganisms are very small, not visible with an eye, including bacteria, viruses, fungi, and parasites.
Even though som of microorganisms can make people ill, many of them are not harmful, all the contrary, they can help a human with digestion, protect him from infections and keep the health good.
Explanation:
You have bad microorganisms in the body, called pathogens. Pathogens can be very harmful and kill all the good cells in the host. That is why good microorganisms are important. They make colonies and protect the body from the development of pathogens that release toxins into the body.
Good microorganisms provide nutrition for the organism, they involve minerals, produce hormones and stop bad microorganisms enter the organism.
Answer:
Man's genotype: XᴮY
Woman's genotype: XᴮXᵇ
Daughter's genotype: XᵇXᵇ
The daughter is not the man's child.
Explanation:
Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).
Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.
Since the man has normal color vision, his genotype would be XᴮY.
If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.
The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
