A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?
Answer:
3.62L
Explanation:
Using Boyle's law equation i.e
P1V1 = P2V2
Where;
P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?
P1V1 = P2V2
81 × 4.2 = 94 × V2
340.2 = 94V2
V2 = 340.2/94
V2 = 3.619
V2 = 3.62L

The artificial cell in the picture below is permeable to monosaccharides but not polysaccharides. Initially, the artificial cell contained a solution of glucose and starch while the beaker was filled with only water. After a period of thirty minutes, the water solution in the beaker tested positive for glucose. What process allowed for this to occur?
Answer:
Osmosis.
Explanation:
Osmosis is the process which is responsible for the transportation of glucose inside the cell. Osmosis is a process in which micro-molecules such as glucose, ions and gases etc go inside the cell through a semi-permeable membrane. This semi-permeable membrane of the cell only allow monosaccharides but not polysaccharides because monosaccharides is small in size while polysaccharides are larger in size.

The first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.
What is Trophic level of Food chain?The term "trophic level" refers to an organism's place in the food chain and has a range of one for primary producers to 5 for humans and marine mammals. The mean trophic level of the consumer's prey is multiplied by one to determine the consumer's trophic level.
The trophic levels are divisions into which species in food webs get categorised. These levels can be roughly categorised as producers (first trophic level), consumers, and decomposers (last trophic level). The first trophic level is producers. The first trophic level receives 100% of the energy from the sun, which has the greatest amount of energy, while subsequent trophic levels only receive 10% of the energy of the level before them.
Thus, the first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.

An egg, a model of a cell, is placed in a concentrated sugar solution (hypertonic) for 24 hours.
What will happen to the egg? The egg will
1. lose mass and shrink in size
2. gain mass and increase in size.
3. stay the same mass and size.
Answer:
gain mass and increase in size
Answer:
1. lose mass and shrink in size
Explanation
the egg is a more dilute solution that the one it is placed in. Through osmosis it will lose water until both solution(the inside and outside of the egg) have roughly the same concentrations. Losing water will cause it to shrink.

Compare the environmental impact of using solar, geothermal, and nuclear energy.
Answer:
Both the sun and geothermal are considered renewable energy sources. ... nuclear energy produces nuclear waste, but solar and geothermal energy does not produce large amounts of waste.
Explanation:
The nuclear energy has more environmental impact as compare to solar energy and geothermal energy. The nuclear energy produces nuclear waste where solar energy and geothermal energy is renewable source of energy.

Explain why the blood vessels and the heart are not made of the same type of muscle even though they are both involuntary.
Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.
Explanation:
IM not sure if this would help but their you go.
Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.
What are Muscle fibers?Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.
Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.
Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.

Ecosystems Unit Test 8 of 8 Items Item 8 Discuss an ecosystem in which there is a producer, a consumer, a secondary consumer, and a decomposer. Name the ecosystem and specific organisms for a producer, consumer, secondary consumer, and decomposer
Answer:
The ecosystem, in this case, is a forest. The producers are plants. The deer, who eats the plants, is the consumer. The wolf, who eats the deer, is the secondary consumer, and earthworms are the decomposers.
Explanation:
An ecosystem is a group of beings that are in a certain area where they interact with each other and with their surroundings. In this case, we describe a trophic level with beings that are in the forest.
Producers are beings that produce their food, like plants.Consumers or primary consumers are animals that eat producers. They are herbivores.Secondary consumers eat primary consumers. They can be omnivores, or like in this case, carnivores.Decomposers are bacterias, mushrooms, or earthworms. They act on all levels breaking down the rest of the animals and plants, obtaining nutrients to nourish the soil, and start the cycle again.how to get big and all thing

process
Answer:
Feedback
Explanation:
A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.
- The input is what is taken in by the system.
