Energy flows in food webs according to the 10% rule, which states that only 10% of the energy stored as biomass in one level is transmitted to the following level.
How is energy transferred between organisms in a food web?
Food webs are interactions between different organisms involving transference of energy when some of them feed on the other ones. The ones placed at lower levels pass energy to the ones at the higher levels.
Energy flow occurs according to the 10% rule, which refers to the energy flow along the trophic chains from autotrophs to heterotrophs and detritivorous organisms.
Only 1% of the solar energy that reaches the Earth's surface is absorbed by autotroph organisms. From there, each trophic level transmits 10% of its energy to the following trophic level. The remaining 90% is lost to the environment as heat.
The 10% rule states that only about 10% of the energy stored as biomass at one trophic level per unit of time ends up as biomass at the next trophic level, in the same unit of time.

Answers
Explanation:
Cellular respiration takes place in the mitochondria while Photosynthesis takes place in the chloroplasts because of the light absorbing tools within the chloroplasts, chlorophyll.
Plants need Carbon Dioxide to perform photosynthesis along with water and light. Photosynthesis is the inverse of cellular respiration and so the equation for each would be as follows

What type of system should your pack use-an open system or a closed system? Explain.
Answers
The type of system your pack should use, either an open system or a closed system, depends on the type of activity you plan to engage in, the climate, and the environment you will be operating in. An open system is characterized by adequate ventilation, allowing air to move freely in and out of the system. Open systems are typically more suitable for warm or hot climates, as they allow for air flow to help regulate body temperature and prevent overheating. They are also generally easier to maintain and lighter in weight compared to closed systems.
On the other hand, closed systems are typically sealed and do not allow air to move in and out. They are better suited for colder environments and activities, as they provide insulation and prevent cold air from entering the system. However, they can be heavy and require more maintenance than open systems. Ultimately, the decision between an open system and a closed system will depend on the specific needs and requirements of the activity and the environment in which it will take place.

Answers
The characteristic that is most responsible for the differences in weather between the Atacama Desert and Salta, Argentina is H) the dryness of the Atacama Desert.
The Atacama Desert is located on the western side of the Andes Mountains, which blocks moist air from the Pacific Ocean, leading to very little precipitation in the area. Salta, on the other hand, is located on the eastern side of the Andes, where moist air from the Atlantic Ocean is able to reach the area and cause precipitation.
it is the dryness of the Atacama Desert that is the main factor responsible for the lack of precipitation in the area, rather than any of the other options listed in the question.

The brown tree snake is a native species in Australia. In the twentieth century, brown tree snakes were accidentally transported by ship from Australia to Guam. These snakes prey on birds, lizards, bats, and rodents such as mice. The population of brown tree snakes in Guam grew rapidly because these snakes had few predators and little competition for food. Eventually, the snakes destroyed entire populations of small mammals and birds. The biodiversity of Guam was harmed. A scientist wants to improve the biodiversity of Guam by controlling the brown tree snake population. Which of the following should be included in the scientist's solution? A new species that can breed with brown tree snakes should be introduced into the ecosystem. Poison that is toxic to brown tree snakes should be placed with dead mice, and the mice should be placed in areas with large numbers of brown tree snakes. People living in Guam should move to new locations away from brown tree snakes. All ships coming from Australia should be inspected to make sure there are no brown tree snakes on board.
Answers
Answer:
D
Explanation:
D) All ships coming from Australia should be inspected to make sure there are no brown tree snakes on board.
The most effective solution for controlling the brown tree snake population in Guam would be to prevent their introduction and spread in the first place. As the brown tree snakes were accidentally introduced to Guam through transportation, the scientist's solution should focus on preventing further introduction of these snakes into Guam.
Therefore, inspecting all ships coming from Australia to ensure that they are not carrying brown tree snakes on board would be the most appropriate solution. This would prevent any additional brown tree snakes from entering the ecosystem and allow for the restoration of the biodiversity of Guam.
Option A is not appropriate as introducing a new species could cause unforeseen ecological consequences and harm the native species further.
Option B is not effective as it could harm other animals in the ecosystem.
Option C is not a practical solution as moving people from Guam would not be feasible, and it does not address the root cause of the problem, which is the introduction of the brown tree snake.

In contrast, light moths had a survival advantage in forested Birmingham before industrialization when tree trunks were lighter in color.
In industrial Dorset, where pollution had darkened the tree trunks, Kettlewell found that dark moths had a survival advantage, as they were better camouflaged against the darker tree trunks. Light moths, on the other hand, had a survival disadvantage in industrial Dorset, as they were more visible to predators against the darkened tree trunks.

Explain the difference between radial and bilateral symmetry in animals, and give an example of each type
Answers
Answer:
Radial symmetry is a type of symmetry found in animals where the body parts are arranged in a circular or radial pattern around a central axis. This means that any plane passing through the center of the animal's body will divide it into two equal halves. Radially symmetrical animals are typically found in aquatic environments, where they can move in any direction to capture food or avoid predators. Examples of radially symmetrical animals include jellyfish, starfish, and sea urchins.
Bilateral symmetry is a type of symmetry found in animals where the body is divided into two equal halves along a single plane. This means that there is only one way to divide the animal's body into two equal halves. Bilaterally symmetrical animals are typically found in terrestrial environments, where they move in a forward direction to capture food or avoid predators. This type of symmetry is also associated with the development of a head region, where sensory organs and a mouth are located. Examples of bilaterally symmetrical animals include insects, fish, mammals, and humans.
