Lettuce or spinach becomes crunchy in water because it draws water back into its vacuoles.
How do they get crispier when you add water?Plant cells will be made up of an outer wall that is rigid in addition to the cell membrane, and will also have a vacuole in its center filled with water that is responsible for keeping the cell swollen. So when adding lettuce or spinach to a medium full of water, the water will enter the cell to maintain homeostasis in the medium, since there will be more water outside than inside.
This will then cause the cell to become swollen and firm, making the lettuce or spinach firm and crisp again.
Therefore, we can confirm that lettuce or spinach becomes crunchy in water because it draws water back into its vacuoles.

Answer:
The cold water isn't able to dissolve as much sugar as the hot water. Another name for the liquids inside the cups is a 'solution', when this solution can no longer dissolve sugar it becomes a 'saturated solution', this means that sugar starts forming on the bottom of the cup.
The reason the hot water dissolves more is because it has faster moving molecules which are spread further apart than the molecules in the cold water. With bigger gaps between the molecules in the hot water, more sugar molecules can fit in between.

Ecological succession is the method by way of which the mix of species and habitats in an area changes over the years. regularly, these groups replace one another till an environment community like a mature woodland is reached, or till a disturbance, like a fireplace, happens. Ecological succession is an essential idea in ecology. Abiotic elements together with soil excellent, water, and weather will determine the species that retain the method of succession.

is a farm a good example of nature coexisting in balance? why or why not?
Answer: Farming needs more and more support in society to get further subsidies. This will only be possible when the ecological benefit can be proved. Up to now a method to measure biodiversity and the ecological benefit of farms is missing. In Baden-Württemberg (Germany), farmers and agri-environment experts have worked together to devise schemes to record the ecological richness and benefits of farms, especially in biodiversity and cultural landscape issues. The scheme uses 47 different indicators divided into four sectors, biodiversity-structural richness, biodiversity-species richness, farm management, and field management (farming methods). Farmers can perform the assessment themselves, on average-sized farms in Southwest Germany one working day may be sufficient. After assessing the ecological situation of the farm an evaluation can easily be made in the form of a natural balance scheme. The presented nature balance scheme is based on a 100-point target system revealing the ecological benefits and shortcomings of the farms. The paper presents results after applying the method to 16 farms in different natural environments and especially the case study Gengenbach (10 farms). Four out of 10 farms achieved the target of 100 points and thus it could be stated that they manage sustainable agriculture in the sense of biodiversity and environmentally sound farming. The results are encouraging because they show that the method works well and farmers become aware of the ecological situation of their farms.

A decision to do something a little bit more or a little bit less is referred to as a margin choice. Making decisions at the margin can reveal very insightful information. Virtually almost all choices, are made at the margin. Individuals do not make choices about whether they should or should not consume something or not. Rather, they decide whether to consume a little more or a little less of it.

InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesisConsidering the given data; to calculate the percentage of the cell cycle spent in each stage of the cell cycle, the formula below is used:
% of the cell cycle spent in this stage = number of cells in given stage ÷ total number of cells counted × 100Total number of cells = 50
% of the cell cycle spent in interphase stage = 34/50 * 100
% of the cell cycle spent in interphase stage = 68%
% of the cell cycle spent in prophase stage = 8/50 * 100
% of the cell cycle spent in prophase stage = 16%
% of the cell cycle spent in metaphase stage = 3/50 * 100
% of the cell cycle spent in metaphase stage = 6%
% of the cell cycle spent in anaphase stage = 2/50 * 100
% of the cell cycle spent in anaphase stage = 4%

Which equation shows how cells use the energy stored in an energy carrier?
A. ADP + H+ → ATP
B. NADPH →NADP+ + H+
C. NADP+ + P→ ATP
D. ATP → ADP + NADPH
The equation that shows how cells use the energy stored in an energy carrier is as follows: ATP → ADP + NADPH (option D).
How is energy used in the cell?Energy is the capacity to do work and a very important criterion for every metabolic activity that occurs in living cells.
The energy currency in the cells of living organisms is Adenosine triphosphate (ATP). ATP is a biomolecule that is used as a source of energy in cellular reactions.
Energy is stored in the cell when a phosphate group is added to ADP while the energy is dispensed for use when phosphate group is lost from ATP to become ADP.
This means that the equation that portrays how cells use the energy stored in an energy carrier is as follows: ATP → ADP + NADPH.
