Answer:

A neuron receives stimuli consisting of the response of  thousands of neurons. Synapse is the signals entering the neuron  via junctions called. The role of  the synapses are to modulate the signal strength and  determine the input signal is either excitatory,  promoting the neuron to fire, or inhibitory, tending to  prevent the neuron from firing. At the axon hillock the  neuron integrates the inputs and if this total is excitatory  then the neuron fires. Although this brief description  leaves out much of the complexity, it is still remarkable  that out of this web of electrochemical firing units,  emerges our very conscious.

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed
STALIN [3.7K]

<u>Answer:</u>

Although statements are not given in the question, we could make the most possible deduction as follows:

The allele for purple flowers is dominant whereas allele for white flowers is recessive.

<u>Explanation:</u>

According to the question,

  1. Purple flower plant was crossed with white flower plant.
  2. All offsprings have purple flowers.

Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.

Regulatory proteins typically contain sites that can bind to other proteins or small molecules. Through such binding interaction
nasty-shy [4]

Answer:

Regulatory sites e.g enhancers and silencers

Explanation:

Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.

Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.

Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.

Why is death by predators more natural or 'right' then death by starvation?
Morgarella [4.7K]
Well because death by starvation would be far more agonizing than death by predators. Starving to death would last longer and the death would be more excruciating.
