Answer:
Phenotype genotype Number of individuals
Red RR 245
Pink Rr 210
White rr 45
Number of alleles in total
R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency
r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency
Predict (Hardy Weinberg) genotype frequencies=
p^2 + 2pq + q^2 = 1
p= 0.7
q=0.3
0.49 + 0.42 + 0.9 =1
According Punnett Squares in F1 we have=
Rr* rr = Rr 50% and rr 50%
Answer:
B
Explanation:
Answer B is correct:
Because the biologists are continuing to learn more and more about such minute organisms, protozoan systematics – that is, the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a topic of debate and change, still today.
Some of the rather LARGE and unwieldy taxonomic groupings of past years are particularly subject to revision with expansion of and refinement in the knowledge about the members of those – and related – assemblages. Paradoxically, the protozoa themselves are becoming more difficult to define with precision as our information about them and other microbial assemblages increases. Thus, presenting a single satisfactory circumscribed definition for them is not an easy task.
...
Answer A sounds so funny.
Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

Answer:
C. Independent variable
Explanation:
The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable.
According to this question, an experiment is conducted to determine what concentration of disinfectant is most effective in killing bacteria. The independent variable is the CONCENTRATION OF DISINFECTANT because it is the variable being changed or manipulated.
Answer:
Water. Plant cells have a large central vacuole that tends to store a great deal of water
