8 0

Answer:

Roots are dynamic, and the environmental conditions in the root zone have a big impact on their growth. They require air (gas exchange), water, non-limiting temperature, carbohydrate, mineral, space, low soil density, microbial associations, and non-toxic soil chemistry in order to survive and develop.

aksik [14]

Answer:

A) Brain genomic library and muscle genomic library.

B) Brain genomic library and muscle genomic library - overlap completely.

Human brain cDNA library, and a human muscle cDNA library and other library is partially overlap.

Explanation:

A) The genomic library contains the whole genome content of the organism whereas cDNA library contains the coding genome of the organisms. Brain genomic library and muscle genomic library will constitute the all the genomic sequences of brain and muscle.  The cDNA library is prepared from the mRNA and the coding regions are present in this library.

B) The overlapping in the genome library might occur due to the common sequences present in the genome. Brain genomic library and muscle genomic library might completely overlap with each other as they have more sequence common among each other. All the other library may be partially overlap with each other as they have some common DNA sequences and neither library can have unique sequences.

The stimulation of an inadequate number of sodium channels for the generation of a positive sodium channel feedback loop is cons
diamong [38]

Answer:

Sub-threshold

Explanation:

If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.

The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.
