the speed at which hummingbirds fly because that is actually a part of physics
Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.
The question is incomplete. The complete question is attached below.
Answer:
1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.
2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.
3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .
4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
the controlled variables are, timing of adding ice, water used, and amount of sugar. the dependant variables are, daily temperature, and amount of lemon juice. the independent variable is, number of glasses sold. hope it helps

Answer:
The correct answer is option D. True tissues.
Explanation:
The cell that made sponge does not form the tissue however sponge have cells that play important role and specific for specific function but does not have true tissues.
In other animal phyla cells form tissue or organ or organ systems and called as true tissues.
Thus, the correct answer is option D. True tissues.
