1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.
2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.
3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
Answer:
All rivers have a starting point where water begins its flow. This source is called a headwater. The headwater usually come from rainfall or snowmelt in mountains.
Explanation:
This is considered false. Although the percentage of all air remains the exact same regardless of altitude, it all matters about the air pressure in the atmosphere. Even though the percentage would be the same, there would be fewer oxygen molecules at higher altitudes and lower pressure.
D) traits that make them more successful in the enviorment
Answer:
Temperature
Explanation:
An experiment has an independent variable which is a factor changed during the experiment. Effect of changes in the independent variable on the dependent variable is seen during the experiment.
According to the question, the experiment was set to observe the effect of temperature on bacterial growth. The bacterial population was exposed to different temperatures. Since the temperature was changed to observe its effect on bacteria growth, the temperature is the independent variable here.
