Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.
This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

Think about pushing two boxes of different weights across the floor-one box is a lot heavier than the other box. How will the amount of force change as you push each box? Explain how this relates to energy expenditure of two people-one person who's heavler than the other.
This is on plato and edmentrum. :)
Answer:
More force is needed to push the heavier box. Likewise, people who weigh more use more energy to move their bodies than people who weigh less.
Explanation:
copied directly from edmentum/plato

A hand sanitizer was advertised to be more effective at killing bacteria than any antibacterial soap. Students were split evenly into 4 groups to test this claim. Groups 1-3 washed their hands using the assigned hand sanitizer or soap (see table) and warm water for two minutes, and then dried their hands with a paper towel. Group 4 rubbed their hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then dried their hands with a paper towel. After washing, each student’s hands were swabbed and the swab was applied to a culture plate and incubated. Finally, the bacterial cultures were counted. what is the independent variable?
Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.
what adaptations facilitated movement of tetrapods to land - be sure to describe challenges that these adaptations helped them overcome.
Answer:
The second neck vertebra evolved to allow rotation of the neck for moving the head left and right. As tetrapod species continued to evolve on land, adaptations included seven or more vertebrae, allowing increasing neck mobility.

Do you guys know the answer????
Answer:
X=16
Explanation:
We would need to convert the whole number (5) into a fractIon. By doing this, we multiply 5 by 3 to get 15. We also must add in the 1 form the 1/3 in the 5, getting 16 for a total, then Adding 16 to the whole equation would be 16/3 or x=16

Explanation:
A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker
Answer:
B in both directions at the same rates
Explanation:
Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.
In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.
In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.
What happened when there was not enough carbon dioxide in the atmosphere to trap the sun's heat about 600 mya?
Answer:
Decreased Temperatures
Explanation:
Because carbon dioxide traps heat in the atmosphere, a lessening of atmospheric carbon dioxide concentrations would mean that more heat could escape into space. This would result in a net decrease in the Earth's average temperature, assuming other factors remain the same.

explain why the suspension of isolated chloroplasts became alkaline when illuminated?
Answer:
Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase. More important is that illumination is required for carbon fixation. As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in. In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.
Explanation:
Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.
Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.
When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.
As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.
Therefore, the formation of carbonic acid from the CO2 will raise the pH.

Answer:
most potteries were Circular, Such as in Egypt they had slavery, but it wasn't like European slavery. They would grow their farms to provide for their families. one main way was to carry water back for their crops in circular plates and vases.
You could say Egyptian slavery wasn't slavery. it was mainly just everyone fending on their source of crops. And everyone could sell their crops for more produce.

Explanation:
We can inherit from our parents a lot of visible traits that can be observed with the naked eye. A phenotype is something that an individual organism got from its parents but we can observe it just by looking at it.
