PLEASE HELP! WILL GIVE BRAINLIEST. Describe the contribution of photosynthesis and cellular respiration to the exchange of carbon between the atmosphere and the biosphere.
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
Answer:
Explanation: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
what do we call the number "2" in CO2?
Answer:
CO2 is the chemical formula for the compound carbon dioxide. C is the symbol for the element carbon, and O is the symbol for oxygen and the 2 just means there are 2 elements from the elements table that makes this element up

What are 2 other differences between plant and animal cells besides cell walls?
Answer:
. The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles. In animal cells, the mitochondria produces the majority of the cells energy from food.

Phototropism is a phenomenon observed in plants. Phototropism is best described as a plant’s response to light. Auxin is a hormone and signaling molecule found in plants that promotes cell elongation. It is observed that auxin concentrations are lower in the parts of the plant that are closest to light. Auxin concentrations are higher in the parts of a plant that are in the shade.
Answer the following in the space provided.
A. Describe phototropism using what you know about signal transduction. Start with auxin as a signaling molecule.
B. Explain how altering the receptor would affect the signaling pathway.
C. Predict how a plant would respond to exposure to light on all sides of a growing stem.
D. Provide reasoning and justification for your prediction.

I'd say FLPE is the worst. It can run high temperatures but it's not safe and not safe with all foods, it's has a high cost.
How are glaciations related to Earth's position in a Milankovitch cycle
Answer:
The Milankovitch Theory explains the 3 cyclical changes in Earth's orbit and tilt that cause the climate fluctuations occurring over tens of thousands of years to hundreds of thousands of years. ... When the orbit is more elliptical, glaciation is affected by the time of year (season) that Earth is closest to the sun.

Explanation:
Como se chama a transferencia de enrgia termica flui de um corpo com maior temperatura quando ao outro de menor temperatura quando ha diferença de temperatura entre ambos
Answer:
Conduction.
Explanation:
Conduction is the process in which heat energy is transferred from the hotter body towards colder body because of temperature difference between two bodies. Conduction occurs only due to physical contact between two bodies. In the conduction process, the thermal energy flows from a body with a higher temperature to the other body having lower temperature until both bodies having same temperature.

In 100 words or more, construct and argument supported by empirical evidence to compare and contrast the
characteristics of viruses and organisms.
Help me
Answer:
Organisms and viruses both do not contain a DNA enclosing nucleus; however, these organisms differ greatly in the complexity of their structures. Generally an organism is encompassed within a semi-rigid cell wall made of peptidoglycan, which provides structural support. It is classified as gram positive if its cell wall is thick and stains purple when tested for identification. If its cell wall is thin and stains red, it is referred to as gram negative. Under the cell wall, the organisms also has a plasma membrane made up of a phospholipid bilayer with proteins inserted inside. Within its cytoplasm, ribosomes for protein synthesis and a single

how does the hadley cell transport heat in the atmosphere?
Answer:
In the Hadley cell, both sensible and latent heat are transported equatorward near the surface, while potential energy is transported above in the opposite direction, poleward. The resulting net poleward transport is only about 10% of this potential energy transport.
