What else can I help you with?
When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings the F2 generation showed a phenotypic ratio of 3 1 and not 9 3 3 1?
Your answer is A
The Chicago School showed a correlation between crime and what?
The weather.
What civilization showed Romans the display of gladiator fights?
The Etruscan civilization that ruled much of the Italian peninsula showed Romans the practice of gladiator fights. Later on when the Etruscans were defeated largely by the Roman City State, this practice continued.
How did you get the story of Genesis from the Bible?
God showed Noah all that had happened and he wrote it down.
Use surfeit in a sentence?
Rashed showed great surfeit when he ate 25 sandwiches.
What is the generation in Mendel's experiment showed both forms of the trait in a ratio of 31?
the F1 is 3:1
What did mendel conclude after his stem height pea plant experiment?
Mendel's experiment showed that with other traits it showed a similar pattern and also that it resulted that this crossed the first generation. The dwarf height traits had seemed to disappear. He then let the first generation plants self pollinate.
What experiment did Pasteur conduct to demonstrate that there was no spontaneous generation of life?
Louis Pasteur conducted the swan-neck flask experiment to demonstrate that there was no spontaneous generation of life. He showed that when broth was heated and sealed in a flask with a curved neck, no microorganisms grew, proving that life did not spontaneously arise from non-living matter.
In Mendel's experiment why did traits show up in the f1 generation that were not present in the f1 generation?
the traits were recessive
How did Louis Pasteur disapprove of spontaneuos generation?
Louis Pasteur disproved spontaneous generation through his famous swan-neck flask experiment. He showed that microorganisms in the air could not enter the flask after it was boiled, thus preventing the growth of microorganisms. This experiment demonstrated that life did not arise spontaneously but came from pre-existing life forms.
How did Pasteur's experiment differ from spallanzani experiment?
Pasteur's experiment on spontaneous generation showed that microorganisms do not arise spontaneously but are introduced into broths from external sources. Spallanzani's experiment involved boiling nutrient broth in sealed flasks to sterilize it, then observing that no microorganisms grew unless air was allowed to enter the flask, suggesting that microbes were not generated spontaneously but entered from the air.
What generation showed hidden traits in all plants of Mendel's experiments?
The F2 generation showed hidden traits in all plants of Mendel's experiments. This generation resulted from crossing the hybrid F1 generation plants, allowing recessive traits to resurface and become visible in the offspring.
What was Mendel's results to his first experiment?
In Mendel's first experiment with pea plants, he crossed true-breeding plants with contrasting traits (e.g., tall and short). He found that the first generation (F1) offspring all displayed one of the traits, while the second generation (F2) showed a 3:1 ratio of the dominant to recessive trait. This led him to formulate his principles of inheritance, now known as Mendelian genetics.
Why is redi's experiment on spontaneous generation considered a controlled variable?
Redi showed the need to limit/control outside variables when he covered 1/2 the jars and got different results than the uncovered.
The Standard prison experiment showed that?
Situations have a powerful influence on behavior '-'
What is Pasteurs experiment?
Louis Pasteur's experiment on spontaneous generation in 1861 involved boiling broth in a flask with a curved neck to prevent dust particles from entering. The broth remained uncontaminated, disproving the theory of spontaneous generation and supporting the idea of biogenesis, which states that living organisms can only arise from preexisting living cells.
What Is The Independent And Dependent Variables in Galileo Pendulum experiment?
Galileo's pendulum experiment showed that the period of the swing is independent of the amplitude (size) of the swing. So the independent variable is the size of the swing, and the dependent variable is the period. The experiment showed there was no dependence, for small swings anyway. The experiment led to the use of the pendulum in clocks.
