In an ecosystem, a group of birds eat fruit from a tree. When the birds drop the fruit on the groundthe mice ea the fruit. Seeds are spread around the area by both the birds and mice and new trees grow. What is this an example of ?
Answer:
The correct answer is - interdependence.
Explanation:
In this ecosystem, all the organisms, tree mice, and birds all depend on one another for their food and growth. Birds get their food from fruits from the tree and the fruits that dropped by the birds to the ground used by the mice for their food.
In return mice and birds spread the seeds of the tree to the area which helps in the growth of the more trees. This relationship among the organisms is an example of interdependency.

Using the diagram below, answer the following questions:
- True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
- True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
- Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
- Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
- Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. ... Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. 8.arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?
Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.
PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.
The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.

For a specific cactus plant, cacti homologous for red flowers were crossbred with cacti homologous with white flowers. The next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.
What is incomplete dominance?Incomplete dominance is a type of inheritance where the offspring that is produced is neither like the paternal parent nor like the maternal parent but will show the different intermediate type of trait that is pink in this case. Here , the pink trait is the intermediate trait of the red and the white that is present in both of the parents, and this type of the offsprings shows different trait when they have the heterozygous states. When this two pink flowers cross then there are the production of the one red, one white and two pink flowers.
Hence, the next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.

In Aquarium C, would the water level on the side with 30% solution of NaCl be higher, lower, or equal to the water level on the side with 5% solution? Explain
Answer:
In Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
Explanation:
The movements of molecules based on differences in concentrations of these molecules in different regions is explained by the phenomena of diffusion and osmosis.
Diffusion is the movement of moleculesmfrom regions of higher concentrationto regions of lower concentration until equilibrium concentration is attained.
Osmosis which is a special form of diffusion involving water molecules is the movement of water molecules in a solution across a semipermeable memebrane, from regions of high solvent concentration (low solute concentration) to regions low solvent concentration (high solute concentration) until equilibrium is attained.
A 30% solution of NaCl is more concentrated than a 5% solution of NaCl, therefore, water molecules will move across the semipermeable from the 5% solution to the 30% solution. This will result in a rise in the water level in the 30% solution.
Thus in Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.

Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. The transfer could only occur during the day because solar energy cannot be stored. The transfer could only occur during the day because solar energy cannot be stored. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. The cost to transfer electricity produced by solar energy over great distances can be high.
Answer:
The transfer could only occur during the day because solar energy cannot be stored.
Explanation:
The transfer of electricity produced from solar energy only occur during the day because solar energy cannot be stored at huge level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, very big batteries are needed to store it which can't be made due to very high cost so that's why the solar energy can not be stored.
