Answer:
The constants: 14 hours of light per day; food one time per day 5 oz; wheel for exercise; cage size
The independent variable: the temperature
The dependent variables: length and weight
Data to be collected: weight of mice; length of mice
A flaw in the experiment: the sample size is to small to be random; it doesn't specify a control group
Explanation:
The constants are the controlled variables. The scientist controls these items because a variable that remains unchanged prevents it from having any effect on the outcome.
The independent variable is the condition manipulated by the scientist to see its effects.
The dependent variables are the ones being measured or tested for in an experiment.
Randomization means every subject gets an equal chance at being in the control group. There are to few subjects. A control group would consist of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter.
Interphase preps the cell for mitosis; telophase, prophase, and anaphase are all parts of mitosis
Answer:
Explanation:
Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin.A compartment is a separate space within a larger whole. In relationship to the endomembrane system and the nucleus.organelles that aren’t part of the endomembrane system, such as mitochondria and chloroplasts.Cellular compartmentalization allows cells to optimize the efficiency of the processes that occur within organelles. But despite the advantages of compartmentalization, it’s not a universal feature of life. In fact, compartmentalization of cellular functions into membrane-bound organelles is limited to only one of life’s three major groups, or domains. That domain is the one that we belong to, the Eukarya. In addition to animals, eukarya includes plants, fungi, and other organisms with eukaryotic cells: cells that are relatively large, complex, and compartmentalized. And to see why that is, we need to look at how life has diverged over time.
The answer is; A.
If r allele is found in 15% of the population, then the frequency of the allele is;
r = 15/100 = 0.15
Remember the equaition p + q = 1
Therefore; R + r = 1; R + 0.15 = 1; R = 1-0.15 = 0.85
RR = 0.85*0.85 = 0.7225
In percentage = 0.7225*100 = 72.25
