Answer:
I dont know what your experiment is but the control variable is the thing your keeping the same.
Explanation:
Population decreases by 15.
Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative). So, just add and subtract the appropriate numbers:
Negative 15 people means that the population decreases by 15.
Answer:
Genes are portions of DNA that contains information to encode proteins
Alleles are different forms of one gene
Chromosomes are closed circular DNA molecules that contain the genetic material of an organism
Explanation:
Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).

As more moisture is added to this air, the rate at which water will evaporate will probably decrease
Explanation:
As long as the air above the lake remains at a constant temperature, the relative humidity of the air will rise with increased evaporation of the water from the lake.
This will continue to increase until the relative humidity reaches approximately 50% and then the evaporation decreases until the saturation point of the air mass is reached where evaporation virtually stops because the air cannot take up more moisture. At saturation point, the rate at which the air mass loses moisture back to the lake (as dew) becomes equal to the rate at which the lake loses water to the air.
