The nutrient is phosphorus
<h3>The phosphorus cycle</h3>
Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.
Thus, the cycle being referred to in the illustration is the phosphorus cycle.

#SPJ1
Answer:
1000 mM
Explanation:
Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM
So, V = -60 mV㏒₁₀[K/K']
-60 mV = -60 mV㏒₁₀[K/K']
dividing both sides by -60mV, we have
-60 mV/-60 mV = ㏒₁₀[K/K']
㏒₁₀[K/K'] = 1
taking antilogarithm of both sides, we have
[K/K'] = 10¹
multiplying both sides by K', we have
K = 10K'
K = 10 × 100 mM
K = 1000 mM
So, the intracellular Cl- concentration is 1000 mM
Answer:
False, all plants cells have cell membrane, in addition most of them have also cell wall. They have both
Answer:
The answer is b. Both of them are characterized by selective permeability.
Explanation:
- Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
- c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.
- d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.
