In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

If an average person produces 2 million red blood cells per second, how many red blood cells will be produced in a 24 hours peri
asambeis [7]

I believe the answer is 172,800,000,000 per day (24 hours)

How I Got That Answer:

I calculated 2 million times 60

=120000000 per minute

Then I calculated that times 60 again

=7200000000 per hour

Then I calculated that times 24

=172800000000 per day

When two species compete for the same ecological niche, they cannot coexist because they are competing for the exact same resour
zalisa [80]
The correct answer is B. competitive exclusion.
This law refers to the fact that it is nearly impossible for two species to exist in the same place at the same time together, if they are interested in the same resources. If both species need the same thing to survive, one will have to be stronger while the other one will dwindle in number.

What are some benefits of enzyme production in the process of digestion.
Rudik [331]

Answer:

<u><em>definition;</em></u>

enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work  are called <em>substrate </em> and enzymes convert them into  different molecules called products.

<em><u>benefits of enzyme in digestion ;</u></em>

enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also  lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and  proteins  </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells.  these molecules are  a part of larger molecules like protein ,polysaccharids  and lipids . enzymes like amylaze, lypase   ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen  which is converted into pepsin with the help of H-C-L  hydrochloric acid it takes part in digestion in stomach

In your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. One rattle
ikadub [295]

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).
