Well, certain stem cells are able to become any kind of (somatic) cell (totipotent stem cells), which helps in organ regeneration, etc. the only problem is that removing even one stem cell from an embryo kills the embryo, and people dont like that.

What is the main difference between protein domains and protein subunits? Group of answer choices1. Protein domains do not have
shusha [124]

Answer: 2. Each subunit represents a separate polypeptide chain, while one polypeptide chain may contain several domains.

Explanation: Each subunit constitutes of one polypeptide chain. A polypeptide chain has one particular gene coding for it. thus it simply implies that a protein must have one gene for each subunit.

Many proteins is made up of different protein domains. A particular domain may appear in a variety of different proteins.

domains are stable on there own, they can be exchanged via genetic engineering between one protein and another.

You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plan
Kruka [31]

Answer:

The fourth plant that receives pure water is the control group.

Explanation:

The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>

Which answer best describes the relative refractory period in the neuron?
notka56 [123]
The answer that best describes the relative refractory period in the neuron is The resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.
The refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. Thus, because Na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
