Hi!
In order for cellular respiration to occur in a cell, the cell needs to have glucose molecules to utilize in the reaction which is as follows:
<u>C6H12O6</u> + 6 O2 --> 6 CO2 + 6 H2O + ATP (energy)
Cellular respiration cannot occur in the absence of glucose. Plant cells acquire this glucose from photosynthesis:
6CO2 + 6H2O + light energy = <u>C6H12O6</u> + 6O2
Animal cells do not need to photsynthesize because they acquire the amount of glucose for cellular reaction from their diet/consumption. Herbivores acquire this glucose from plants, carnivores from feeding off other animals, and omnivores from both feeding off plants and animals.
Hope this helps!
respitory systym and circulatory system because you need your lungs to breathe and the blood and heart to pump the oxygen into the blood. :))
Hi Gigi, my name is Ryleigh, I might be able to help, but I need to know what are the conditions, and what is the question asking?
Answer;
-The statements that are true of Pangea include;
A. Pangaea was one of several supercontinents that have formed and broken up during Earth's history.
C. Rates of seafloor spreading in the Atlantic Ocean are compatible with what is known about the breakup of Pangaea.
D. The regional-scale folds visible in the Appalachian Mountains are remnants of Pangaea's formation.
Explanation;
-About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa.
-The movement of Earth's tectonic plates formed Pangaea and ultimately broke it apart. Pangaea existed during the Permian and Triassic geological time periods, which were times of great change.
Answer:
The percentage of space not occupied by solid matter in soil is called :
B. Porosity.
Explanation:
- Porosity is represented as the percentage of void in the soil.
- In simple words, it is the number of pores present in a soil.
- The porosity of soil is a factor that determines the quality and suitability of the soil for agriculture.
- A more porous soil does not hold lot of water and nutrient while a less porous soil retains water and nutrient.
- Thus neither a extremely porous nor a less porous soil is suitable for agriculture.
