B.
Explanation:
My best guess would be because it only state's that it is a gene coded from her father, not mother. So I am assuming that it is controlled by only one gene.
For measuring the temperature of a classroom, the best instrument that one can use is the THERMOMETER. The correct option is D.
Thermometer is the instrument that is specifically designed for the measurement of temperature and there are different types of thermometers for measuring different types of temperature.
Note that, barometer is used for measuring atmospheric pressure, sphygmomanometer is used for measuring blood pressure and atmosphotometer does not exist.
It is true that in the science laboratory setting, scientists often struggle to achieve valid results. A possible solution for this dilemma is to repeat the procedure for several trials.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.
