Answer:
The dependent variable is the biological sex of the alligator hatchling.
Explanation:
A hypothesis is essentially a suggested explanation for a specific phenomenon. These hypotheses attempt to offer well-tested reasons for certain observations through experiments.
Experiments are usually carried out under a variety of different conditions to test various hypotheses. To ensure reproducibility, accuracy, and validity of results, several factors must be identified when planning experiments.
For instance, various independent variables are strictly altered and observed while controls are kept constant - this ensures validity and can indicate if the experiment was influenced by external factors. Here, the factor being changed or tested is the temperature, and the factor being observed is the resulting biological sex of the organism.
Answer:
Multicellular
Explanation:
Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.
As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.
Does this make sense? Feel free to comment any other questions!! If this explanation helped you, please consider leaving me a good review and/or brainliest!! <3
Answer:
The tuba
Explanation:
The tuba produces sound by vibrating or buzzing the lips into a large cupped mouth piece. It produces different pitches by changing the mouthpiece.
Answer:
Friction depends on the coefficient of friction which in turn depends upon the nature of the surface. Hence, this statement
is false.
