Match each neural component with its role in synaptic transmission. Drag each item on the left to its matching item on the right

Anton [14]

Answer:

a. neurotransmitters presynaptic >>>> 2. chemicals that are released into the synapse

b. neuron postsynaptic >>>> 3. integrating information

c. neuron dendrites postsynaptic >>>> 1. receiving information

d. neuron cell body >>>> 4. sending information

Explanation:

Neurons transmit nervous impulses. These cells are composed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli (information) from other cells, and an axon that is a long structure capable of conducting the electrochemical signals. Every neuron forms <em>connections with other neurons</em>. These connections are known as <em>synapsis</em>. As it happens in every synapsis between cells when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area and binds to its receptors in the postsynaptic membrane. This binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it.

Osmosis is the diffusion of water across a membrane in response to the concentration of one or more of the ________.

kondaur [170]

Osmosis is the diffusion of water across a membrane in response to the concentration of one or more of the <u>higher concentration</u>

Osmosis is the movement of water molecules from a region of lower concentration to a region of higher concentration through a selectively permeable membrane

It is a special case of diffusion of water across a membrane in response to the concentration of one or more of the higher concentration

<h3>What is diffusion?</h3>

Diffusion can be defined as the movement of substances from a region of higher concentration to a region of lower concentration

Identify all the amino acid-specifying codons where a point mutation (a single base change) could generate a nonsense codon.

Murrr4er [49]

Answer:

Glutamic Acid (Glu): codons GAA, GAG

Glutamine (Gln): codons CAA, CAG.

Lysine (Lys): codons AAA, AAG, UCG

Serine (Ser): codons UCA, UCG

Leucine (Leu): codons UUG, UUA

Tyrosine (Tyr): codons UAC, UAU

Tryoptophan (Trp): codon UGG

Arginine (Arg): codons CGA, AGA

Glycine (Gly): codon GGA

Cysteine (Cys): codon UGU

Explanation:

Non sense codons are: UAA, UAG, UGA. Then following the genetic code (see attached file) a single base substitution in any of the codons indicated in the answer could generate a stop codon. This single base substitution might happen in the first, second or third base of the codon.

Assume you inoculated 100 cells, with a generation time of 20 minutes, into 100 ml of nutrient broth. You then inoculated 100 ce

Mice21 [21]

Answer:

the same number of cells in both.

Explanation:

Nutrient broth is a general purpose medium that can be used to cultivate different variety of both fastidious and non-fastidious microorganisms.

Nutrient broth is known to contain or compose of simple peptone and a beef extract.

It is known to be used for bacteria that will not form colonies on a solid surface.

Nutrient broth can be prepared through this following steps

* Add 13g of nutrient broth powder in 1L of distilled water.

* Mix and dissolve them completely.

* Pour them into the final containers (eg. conical flask)

* Sterilize by autoclaving at 121°C for 15 minutes.

In this case, since the 100 ml and 1000 ml is prepared using the same method, it is expected to have the same number of cells in the same volume of the broth.
