How does energy flow through organisms
Answer:
Energy "flows" through the ecosystem in the form of carbon-carbon bonds. ... This process releases the energy, which is either used by the organism (to move its muscles, digest food, excrete wastes, think, etc.) or the energy may be lost as heat. The dark arrows represent the movement of this energy

Which of the following choices is the best example of how the cell membrane and mitochondria might work together to make energy in a particular cell?
A. In animal cells, the mitochondria allows materials in and out of the cell, while the cell membrane uses nutrients to make energy (ATP) for the cell.
B. In a plant cell, the mitochondria allows materials in and out of the cell, while the cell wall makes food for the cell by photosynthesis.
C. In a plant cell, the cell wall allows materials in and out of the cell, while the mitochondria makes food for the cell by photosynthesis.
D. In animal cells, the cell membrane allows materials in and out of the cell, while the mitochondria uses nutrients to make energy (ATP) for the cell.
In animal cells, the cell membrane allows material in and out of the cell while the mitochondria use nutrients to make energy (ATP) for the cell. So the correct option is D.
What are mitochondria?
The cellular organelles known as mitochondria are responsible for releasing energy from meals. Cellular respiration is the term for this process. Because of this, mitochondria are frequently referred to as the cell's powerhouses. Numerous mitochondria can be seen in muscle cells and other cells with high energy requirements.
A sequence of chemical events takes place in the cytoplasm when breakdown products from food digestion enter the cell. This enables part of the energy trapped in these products to be released and integrated into ATP, the cell's primary source of energy (adenosine triphosphate).
Therefore, in an animal cell, the cell membrane allows material in and out of the cell while the mitochondria use nutrients to make energy (ATP) for the cell. So the correct option is D

Which kind of soil do temperate climate areas usually have?
-Soil containing little to no organic material
-Soil rich in nutrients
-Soil with a layer mostly composed of clay
-Soil consisting primarily of tiny rock particles
Answer:
Soil rich in nutrients
Explanation:
Temperate soils exist under all types of conditions, including within forests, rain forests and in grasslands, but all have several key things in common. Temperate soils have a rich upper level that is high in minerals and nutrients, and in all cases micro-organisms work to break down decaying matter within the soil.

Compare AND contrast the continental shelf and the continental slope. PLEASE answer its due today!!!
Explanation:
Below the slope is the continental rise, which finally merges into the deep ocean floor, the abyssal plain. The continental shelf and the slope are part of the continental margin. ... The continental slope is much steeper than the shelf; the average angle is 3°, but it can be as low as 1° or as high as 10°.
OR
Continental shelves are gradually slopping ends of a continent that extend under the ocean however continental slopes extend from the outer edge ofthe continental shelf to the ocean floor.

A metal body of mass 81 g occupies a volume of 30 cm3. Identify the metal.
Answer:
Aluminum
Explanation:
The density of Aluminum is 2.7 g/cm3
We know the volume and mass of the unknown metal, as density is mass/volume: 81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)
Given parameters:
Mass of metal = 81g
Volume of metal = 30cm³
Unknown:
Identity of the metal = ?
To find the identity of the metal, we must derive an intrinsic property from the give parameters which we can use to identify it.
This property is density.
Density is mass per unit volume of a substance. Every earth material has a unique value of density.
Density = [tex]\frac{Mass}{Volume}[/tex]
If we find density, we look up a density table and identify the element.
Input the parameters and solve;
Density = [tex]\frac{81}{30}[/tex] = 2.7g/cm³
The metal with a density value of 2.7g/cm³ is aluminium.

Chemical weathering: changes rocks on a molecular level uses temperature changes to break rocks is always slower than physical weathering transports silt and rock to other places
Chemical weathering changes rocks on a molecular level uses temperature changes to break rocks is always slower than physical weathering transports silt and rock to other places - True
Chemical weathering, which can take place at the molecular level, is the disintegration and modification of rocks by chemical processes. Water exposure, exposure to gases in the atmosphere, and acid exposure are all potential causes of this form of weathering. These activities have the potential to alter the composition and structure of the rock over time by dissolving rock minerals.
Chemical weathering can be influenced by temperature variations because certain minerals can expand and contract in response to temperature fluctuations, which can cause cracking and expose new surfaces to chemical reactions. Chemical weathering is often slower than physical weathering, which includes the mechanical degradation of rocks via processes like abrasion or freezing and thawing. The kind of rock and the local climate, among other things, can affect the pace of weathering.

Complete Question:
Chemical weathering: changes rocks on a molecular level uses temperature changes to break rocks is always slower than physical weathering transports silt and rock to other places - True/False?
Answer: Chemical weathering is a process that alters the composition and properties of rocks by breaking them down on a molecular level.
Explanation: This type of weathering typically occurs through the interaction of water and atmospheric gases with minerals in the rock. The chemical reaction that takes place can dissolve or alter the mineral structure, leading to changes in color, texture, and overall appearance.
Unlike physical weathering, which breaks down through mechanical forces like wind or water erosion, chemical weathering does not require any physical force to take place. However chemical weathering is slower than physical weathering, as the chemical reaction involve often occurs over a longer period of time.
As chemical weathering breaks down rocks, it can also transport silt and small rock particle to other locations, where they may settle and accumulate in new formations. This can contribute to the formation of soil and sedimentary rock over time.
