Answer:

The cell membrane is selectively permeable, allowing only certain substances to pass through.

In the initial period of learning, ________ describes when an organism learns to connect a neutral stimulus and an unconditioned
Alexandra [31]

Answer:

The given blank can be filled with acquisition.

Explanation:

An unconditioned stimulus provokes the unlearned response and an unconditioned response is the naturally taking place reaction. A neutral stimulus is illustrated as the stimulus that prior to conditioning do not generate any kind of response.  

A type of learning wherein a subject begins to react towards neutral stimulus as it would perform with another stimulus by acquiring the path of associating the two stimuli is termed as classical conditioning.  

An acquisition can be illustrated as the time of learning in classical conditioning where an individual begins to associate a neutral stimulus with an unconditioned stimulus that further permits the neutral stimulus to begin possessing the conditioned response.

What are the 4 functions of nucleotide​
Leni [432]

Nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.

  • Nucleotides are the building blocks of nucleic acids (either DNA or RNA).

  • These molecules (nucleotides) are composed of one pentose sugar, a nitrogenous base, and one or more phosphate groups.

  • In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).

  • Adenosine triphosphate (ATP) is a nucleotide that represents the energy coin of the cell, which is used to carry out different metabolic functions (e.g., growth, differentiation, reproduction, etc).

In conclusion, nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.
