Answer:
The amount of activity
Explanation:
In an experiment, the independent variable is the variable that the scientist/investigator purposely changes or manipulates, which isn't changed by other variables in the experiment (in this case, the amount of caffeine). On the other hand, the dependent variable is the variable that is being measured or tested during the experimental procedure (this variable is 'dependent' on the independent variable). Finally, the control group is defined as the group of individuals/subjects who do not receive the experimental treatment (in this case, the dogs that receive water).

Answer:
C = 5/9(F - 32)
C = 35
35 = 5/9(F-32)
35 * 9/5 = (F-32)
(F-32) = 63
F = 63 + 32 = 95

Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.

elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
Answer:
The right lung is smaller than the right to make room for the heart.
Explanation:
so the answer is A :)
The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.
The statement that the left lung contains two lobes while the right lung contains three lobes is correct.
The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.
This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.
Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.
Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

PAIR, what is the probable carrying capacity of this environment? *
The carrying capacity of this environment is 225 from the graph shown.
An ecosystem is a self supporting unit in which materials and energy are exchanged. The carrying capacity of an ecosystem refers to the maximum number of species that the ecosystem can effectively sustain without breaking down.
From the graph, we can see that the population of species continues to increase until the number reaches 225. This is the carrying capacity of this environment.

The diagram shows the reproductive system of a plant.
Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.
What is pollination?
Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
Thus it is clear that the answer explained above is correct describes the interaction that occurs between a plant's reproductive parts during self-fertilization.

Definition Of polar molecules and nonpolar molecules please?
Answer:
Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.
Explanation:
When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).
