Explanation:
Explain how your neighborhood can be described as an ecosystem. Include examples of biotic and abiotic factors. Describe the levels of organization found in your neighborhood from the smallest level of organization to the largest. Provide an example for each.
Answer:
Ecologists often work at five broad levels, sometimes discretely and sometimes with overlap: organism, population, community, ecosystem, and biosphere.
Organisms make up a population. Multiple populations of different species make up a community. Communities in a particular area make up an ecosystem. All of the ecosystems on Earth make up the biosphere.
From smallest to largest:
Organism: Organismal ecologists study adaptations, beneficial features arising by natural selection, that allow organisms to live in specific habitats. These adaptations can be morphological, physiological, or behavioral.
Population: A population is a group of organisms of the same species that live in the same area at the same time. Population ecologists study the size, density, and structure of populations and how they change over time.
Community: A biological community consists of all the populations of different species that live in a given area. Community ecologists focus on interactions between populations and how these interactions shape the community.
Ecosystem: An ecosystem consists of all the biotic and abiotic factors that influence that community. Ecosystem ecologists often focus on flow of energy and recycling of nutrients.
Biosphere: The biosphere is planet Earth, viewed as an ecological system. Ecologists working at the biosphere level may study global patterns—for example, climate or species distribution—interactions among ecosystems, and phenomena that affect the entire globe, such as climate change.
An ecosystem consists of all the living organisms and the physical environment which interact with each other. This includes nutrient cycling and energy flow.
What is Ecosystem?An ecosystem consists of all the living organisms and the physical environment with which they interact in the surrounding environment. The biotic and abiotic components in an ecosystem are linked together through nutrient cycle and energy flow. Energy enters into the system through photosynthesis and is incorporated into the plant tissue.
Biotic factor is the living matter which is present in an ecosystem such as the producers which include plants, consumers such as herbivores, carnivores and other living organisms. Abiotic factors include all those matter in the ecosystem which is non-living, such as air, water, soil, temperature, etc.

Explain what happens to the available energy within each level when more organisms exist at that level.
Answer:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Explanation:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Energy can neither be created nor be destroyed. The available energy within each trophic level is lost as heat and only 10% of the energy is utilized.
The 10% rule can be explained as:
1. Energy in the different trophic levels is passed and the rest of the energy is lost as heat.
2. The law suggests that only 10% of the energy is transmitted to different trophic levels.
3. Approximately 80%-90% of the energy is lost in the form of heat. The organisms utilize energy for metabolic processes and keep them warm.
Thus, the rest of the energy is lost as heat and only 10% of the energy is transferred to the next trophic level.

MERCURY HAS A MEAN TEMPERATURE OF 167 DEGREES CELSIUS YET ICE HAS BEEN DETECTED IN DEEP CRATERS. EXPLAIN HOW THIS PRESENCE OF ICE IS POSSIBLE
Answer:
In 0 K =-273.15 C therefore 239 k= -34.15 C
Explanation:
i just happened to find the answer
Mercury is a metal which is liquid at room temperature. It has shown to have unique properties like the presence of ice. This is because the planet does not get sufficient heat transport.
How ice is present on Mercury?Mercury does not have a substantial atmosphere to transport heat around the planet. The darkness of the planet allows ice to remain frozen despite the extreme temperature of the world.
The Earth-based radar imaging of Mercury has revealed areas of high radar reflectivity near the poles that could indicate the presence of ice in these regions. There are dozens of areas with generally circular shapes.
Mercury is the only metal that is a liquid at standard temperature and pressure, all the other metals are solid. The other metals like rubidium, cesium, and gallium melt at a temperature just above room temperature but mercury stay as a liquid at all the temperatures.

Why do phospholipids make a phospholipid bilayer with the heads facing out towards water and the tails facing each
Answer: See below
Explanation:
Phospholipids are organized into two layers. The phospholipids have a head known as a 'hydrophilic' or water-loving head. Any water will come into contact with this region of the phospholipid. In contrast, the phospholipid tails are hydrophobic, or 'water hating'. They will position themselves such that they face inwards and are not in touch with any water. Because of these features, the bilayer is created with the phospholipid heads facing outwards and the tails facing inside.

Answer:
The Cell Cycle | Back to Top
Despite differences between prokaryotes and eukaryotes, there are several common features in their cell division processes. Replication of the DNA must occur. Segregation of the "original" and its "replica" follow. Cytokinesis ends the cell division process. Whether the cell was eukaryotic or prokaryotic, these basic events must occur.
Cytokinesis is the process where one cell splits off from its sister cell. It usually occurs after cell division. The Cell Cycle is the sequence of growth, DNA replication, growth and cell division that all cells go through. Beginning after cytokinesis, the daughter cells are quite small and low on ATP. They acquire ATP and increase in size during the G1 phase of Interphase. Most cells are observed in Interphase, the longest part of the cell cycle. After acquiring sufficient size and ATP, the cells then undergo DNA Synthesis (replication of the original DNA molecules, making identical copies, one "new molecule" eventually destined for each new cell) which occurs during the S phase. Since the formation of new DNA is an energy draining process, the cell undergoes a second growth and energy acquisition stage, the G2 phase. The energy acquired during G2 is used in cell division (in this case mitosis).

Which compound is a product of photosynthesis and a reactant for cellular respiration
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Explanation:
Glucose is a product of photosynthesis and a reactant for cellular respiration.
PHOTOSYNTHESIS:
Photosynthesis is a process in which green plants obtain their food in the presence of sunlight. The chemical equation is as follows:6CO2 + 6H2O → C6H12O6 + 6O2
