24. An investigator examines voltages resulting from changes in membrane permeabilities. If the cell membrane suddenly had 100 p
omeli [17]

Answer:

Generally, K+ ions ensures re-polarization of  the membrane potential. It always ensures that the neuron returns its resting  state, protecting the  neurons and ensuring episode of rest before the next action potential.

K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.

Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.

Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.

Write a 5 sentence paragraph that describes the characteristics that all living things share​
BARSIC [14]

Answer:

<u>Living things are derived from single units and show several characteristics such as growth respiration, response to stimuli, homeostasis, evolution, and reproduction.</u>

Explanation:

The natural world comprises several biotic or living and abiotic, non-living factors. Cells, are considered the smallest unit capable of supporting life.  All living, or biotic factors must be able to grow, carry out respiration- a process that produces energy, and reproduce (pass on genes). They also  show some level of organization or complexity, and respond to stimuli. Additionally, living organisms exhibit homeostasis or control over their internal environment and evolve or change over time to adapt to their external environments.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here
