A scientist is able to isolate a single, intact nerve cell from a human cadaver. Assume the human in life was 6 feet tall. If th

e neuron isolated extended from the spinal cord to the tip of the cadaver toe, how long would it be?

Answer:

a meter or more

Explanation:

The main function of the nerve cells is to send a signal from the brain to other parts of the body, or vice versa. The longest nerve cell would be the one who connects the brain with the receptor in your toe. This mean nerve cell length can be as long as the human height. If the human is 6 feet tall in life, that will be about 1.8m tall.

Serhud [2]

Answer:

Explanation:

Cannibalism is a very essential factor regulating population dynamics of four beetle. After some days of feeding, the flour becomes conditioned by the beetles which can affect rate of cannibalism

Adults have a relatively lower rate of cannibalism. While its highest rate of cannibalism is at larvae stage

Flour conditioning is caused by the accumulation of feces, pheromones and ethylquinone- thus is repellent produced by the beetles.

`what is physical science
Westkost [7]

Physical science is concerned with the inorganic world, including physics, astronomy, certain types of chemistry, and generally, earth sciences.  If it includes non-living things, it is physical science.

how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction
Nikitich [7]
In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.

Use the following words to fill in the blanks: nucleus, base-pairing, transcription, translation, genes, cytoplasm, polypeptide
Mkey [24]

Answer:

Use the following words to fill in the blanks: nucleus, base-pairing, transcription, translation, genes, cytoplasm, polypeptide chain, structure, ribosome, proteins, protein synthesis, cytosine, adenine, uracil, tRNA, mRNA, amino acid, DNA, RNA polymerase, codon.

DNA is made up of segments called  nucleotides

. Genes provide the coding to create  codon

. Proteins are created through the processes of  translation

and  transcription

. Together these processes are known as  protein synthesis

. The first step in protein synthesis is transcription, where translation

is used as the template for the creation of an mRNA strand. The enzyme,  RNA  Polymerase

matches up the correct bases, using  base-pairing

rules. When adenine is found on the DNA strand,  cytosine

will be the complementary base on the mRNA strand. When thymine is found on the DNA strand,  adenine

will be the complementary base on the mRNA strand.

and guanine are the other two bases that pair with one another. Since DNA is too large to leave the nucleus of the cell,  tRNA

must be created. It is smaller and able to travel outside the  nucleus

of a cell. Next, mRNA leaves the nucleus, heads through the  cytoplasm

towards a  ribosome

where translation occurs. In the ribosome, a  codon

on the mRNA strand (3 bases), connects to the anticodon on a  tRNA

molecule. When the codon and anticodon connect, the  amino acid

on the tRNA molecule detaches, forming a  polypeptide chain

which eventually makes up the protein. Proteins are essential for life because they make up the  structure

of living organisms and help organisms to function.
