Answer:
Hypothesis: If there is a rat, THEN an elephant will react differently
Independent variable: Presence or absence of rat
Dependent variable: Elephant's reaction
Conclusion: The hypothesis is accepted because rats make an elephant to react.
Explanation:
A hypothesis is a predictive statement about a particular observation made, which is what we're doing next. In this case, a possible statement that suggests solution could be: If there is a rat, THEN an elephant will react differently.
Independent variable is the variable being manipulated in an experiment. The PRESENCE OR ABSENCE OF RATS is the independent variable
Dependent variable is the variable that the experimenter measures. In this experiment, the measurable variable/dependent is the ELEPHANT'S REACTION.
Conclusion of an experiment either rejects or accepts the hypothesis depending on the outcome of the experiment. In this, let it be assumed that the conclusion has been accepted
Answer: Option C
Explanation: The balanced chemical equation that explains photosynthesis is stated below:
6CO2(g) + 6H20(g) --------> C6H12O6 + 6O2(g) + energy (in from of ATP)
From the equation, 6 atoms of carbon C are contained in 6 moles of atmospheric Carbondioxide CO2, that reacted with 6 moles of water molecules H2O, contained in plant cells to yield 1 mole of glucose C6H12O6 and chemical energy in the form of ATP (adenosine triphosphate)
Answer:
The chromosomes are arranged in their respective homologous pairs. In humans, this displays 22 pairs of autosomes and 1 pair of sex chromosome.
Explanation:
Chromosomes that are similar in their size and shape and also display similar genetic traits and carry the same genetic information are paired together. These are known as homologous chromosomes. These chromosomes carry different variations of similar genes in them. In humans there are 46 chromosomes in total. These chromosomes are paired and form 23 homologous pairs. Among these 23 homologous pairs, 22 pairs are autosomes and one pair are the sex chromosomes which are either (XX or XY). The sex chromosomes determine the sex of an individual. XX chromosomes represent a female and XY chromosomes represent a male.

Answer:
1) Basilar membrane
2) Stereocilia or hair cells
3) Nerve cells
4) Auditory
5) Temporal lobe
Explanation:
Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.
Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.
Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.
Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.
Space is filled with nothing.
Space is the absence of matter.
