Put the steps of the nitrogen cycle in order, starting with the step that
Pepsi [2]

Nitrogen Cycle steps:

N molecules breaking apart via nitrogen-fixing bacteria.

Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.

The organic matter decays via decomposers

N2 is formed via denitrifying bacteria.

Explanation:

The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.

Animals (herbivores) consume the plants that have absorbed nitrogen/

When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia

The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.  

The nitrogen thus formed is released to the atmosphere

When a neuron is activated by a stimulus, its plasma membrane will change until it reaches a membrane potential of about 40 mV.
grandymaker [24]

Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.

Explanation:

The charge in plasma membrane occurs with diffusion and electric fields.

For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).

The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.

For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.

The like charges repel, and opposite charges attract.

Select all that apply. The principal advantages of asexual reproduction are _____.
hichkok12 [17]
The correct answers are A and C.
When an individual is reproducing asexually, it means that there is no fusing of two parent cells and meiosis, but that the offspring is produced out of the cells of one parent. This means that the organism is not '' losing time'' by trying to find a suitable mate, which enables the populations to grow at a rapid rate.
However, the offspring are genetically identical to the parent, which means that there is very little genetic variation in the population which can lead to accumulation of harmful mutations and unresponsiveness to changes in the environment.
