Answer:

Huskies were bred by the Chukchi people in Northeast Asia and Siberia to be sled dogs, reindeer-herding dogs, multi-purpose workers, companion dogs and guard dogs. Today, Huskies are primarily family companions, though many are still pulling sleds in Alaska and other snowy regions.

What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?
Maru [420]

Answer:

Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

Explanation:

Postsynaptic neuron :

These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

There are number of neurotransmitter. These includes

GABA ergic: This neurotransmitter is often inhibitory.

glutamatergic: This neurotransmitter is often excitatory.

Adrenergic: This neurotransmitter releases norepinephrine.

Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.

Write a paragraph on testing probability
VashaNatasha [74]

Explanation:

Probabilities are described as ratios of favorable event outcome to the total number of event outcomes.

This is written as...

P (E) =\frac{n(E)}{n(S)} \\

where...

E= the number of times the event occurs

S= the number of trials

In biology experiments, hypotheses are formed based on research questions, and tested with the use of variables  to provide a particular outcome. Statistics allows for testing data for consistency with the hypothesis, while statistical probability testing can be used in experiments to determine a range of outcomes, from genetic inheritance, evolutionary rates to theoretical experimental results.

In these statistical models, probability distributions are functions that give probabilities for certain event outcomes within an experiment (a set of trials). These may be either continuous, taking a value within a range of two numbers; or discrete, which may be either of two specified values. Discrete probability distributions list each value that a random variable may possibly take on.

Further Explanation:

For example, two types of probability distributions are employed in experimental biology:

Binomial distributions, which are discrete distributions,  provide probability of a certain number of successful events for x  a random variable, in a specific number of trials, n; here, the probability of success of an individual trial is constant at P and only one of two outcomes are possible- this is sampling with replacement.

where...

b(x;  n, P)-the probability that an experiment of n trials results in x successes

nCx- the number of combinations of n things at r time

b(x;  n, P) = [ nCx ]* P^{x}  * (1-P)^{n-x}\\

<em>This is often used in determining potential outcomes before data collection.</em>

A type of continuous distribution, the student's t-test, compares standard deviations and means from two sets of samples or groups to check for significant differences between them.

t= \frac{(x_{1} - x_{2}) }{\sqrt{(\frac{(S_{1}) ^{2} }{n1} }+ (\frac{(S_{2}) ^{2} }{n2 }}

where...

  • x1 and s1 are the mean and standard deviation of sample 1 respectively
  • x2 and s2 are the mean and standard deviation of sample 1 respectively  
  • n1 and n2 are sample sizes in samples 1 and 2 respectively

The null and alternate hypotheses typically theorize the likelihood and significance of certain event outcome probabilities. Critical values of t, along with degrees of freedom are used to determine a range of probable outcomes; probability or p- values along with this range, are used to determine whether either hypothesis is rejected or accepted.

<em>For instance, significant differences between an experimental control and a specific treatment group would show that these occurrences are not due to sampling errors or random chance...</em>
