A stimulus that does not initially elicit a response in an organism is a(n) ________.
a. unconditioned stimulus
b. neutral stimulus
c. conditioned stimulus
d. unconditioned response
A stimulus is considered neutral if it first causes only the attention to be focused. When combined with an unconditioned stimulus in classical conditioning, the neutral stimulus turns into a conditioned stimulus.
An organism initially does not react to a neutral stimuli. The word "neutral" denotes objectivity and independence. As a result, no specific response is connected to a neutral input. When the neutral stimulus is presented repeatedly alongside the unconditioned stimulus at the same time, a response known as a conditioned response will start to be elicited.

In the early 1900s, cities such as Philadelphia reduced the incidence of typhoid fever by
A) isolating human carriers.
B) using tertiary water treatment systems.
C) filtering municipal drinking water through sand-bed filters.
D) requiring residents to boil drinking water.
E) mass vaccination of residents.
In the early 1900s, cities like Philadelphia reduced the incidence of typhoid fever by filtering the city's drinking water through sand bed filters.
In 1906-07, the largest typhoid fever epidemic in history occurred. The infection was due to Emsworth oysters whose oyster beds had been contaminated with raw sewage. The most notorious carrier of typhoid fever, but by no means the most devastating, was Mary Her Marron, also known as Typhoid Her Mary.
Ultimately, Philadelphia adopted a defense that worked well in Europe. That was to clean the water supply with a filtration system. After the construction of filter systems in the early 20th century, the incidence of typhoid fever dropped dramatically and the incidence of the disease was eventually eliminated entirely.

b. astrocyte c. oligodendrocyte d. Schwann cell
Ependymal cell is the type of glial cell is responsible for filtering blood to produce CSF at the choroid plexus.
The central canal of the spinal cord and the ventricles of the brain are lined by ependymal cells, which produce cerebral spinal fluid (CSF). These cuboidal to columnar cells circulate and absorb CSF with the help of cilia and microvilli on their surfaces.
Ependymal cells have a role in the distribution of hormones and neurotransmitters related to the central nervous system, depending on their location. Additionally, the ependymal cells' microvilli have the ability to absorb CSF, control its flow, and allow specific chemicals to enter and exit the brain.

Provide a chi-square value and p-value, and your statistical and biological decision. chi-square value = 15.23 X (round up your answer nearest 100th) 0.1 x > p-value > 0.05 IX Statistical decision: reject (reject / fail to reject) Biological decision: This population is not (is / is not) in HWE.
Based on the chi-square value and p-value, the statistical decision is to reject the null hypothesis that the population is in Hardy-Weinberg equilibrium. The biological decision is that this population is not in Hardy-Weinberg equilibrium.
Chi-square value: 15.23
P-value: 0.05
Statistical decision: Reject
Biological decision: This population is not in HWE.
Step 1: Calculate allele frequencies
To calculate allele frequencies, we need to know the total number of alleles in the population. In this case, there are 400 AA, 400 Aa, and 200 aa individuals, for a total of 1200 alleles. Since there are two alleles (A and a), we can calculate the frequency of each allele by dividing the total number of each allele by the total number of alleles:
f(A) = 400/1200 = 0.6
f(a) = 800/1200 = 0.4
Step 2: Calculate predicted HWE genotype frequencies
Using the allele frequencies, we can calculate the predicted HWE genotype frequencies using the equation:
f(AA) = f(A)*f(A) = 0.6*0.6 = 0.36
f(Aa) = 2*f(A)*f(a) = 2*0.6*0.4 = 0.48
f(aa) = f(a)*f(a) = 0.4*0.4 = 0.16
Step 3: Calculate chi-square value and p-value
The chi-square value is calculated by comparing the observed and expected frequencies of the genotypes in the population. In this case, the observed frequencies are 400 AA, 400 Aa, and 200 aa individuals, while the expected frequencies are 0.36 AA, 0.48 Aa, and 0.16 aa individuals. The chi-square value is then calculated as follows:
chi-square value = 15.23
The p-value is calculated by comparing the chi-square value to a chi-square table with 1 degree of freedom. In this case, the p-value is greater than 0.05.
Step 4: Make a statistical and biological decision
Based on the chi-square value and p-value, the statistical decision is to reject the null hypothesis that the population is in Hardy-Weinberg equilibrium. The biological decision is that this population is not in Hardy-Weinberg equilibrium.

if trans-2-bromocyclohexanol is treated with sodium hydroxide what is the major product?
Trans-2-cyclohexanol would be the main byproduct of treating trans-2-bromocyclohexanol with sodium hydroxide.
As a strong base, sodium hydroxide (NaOH) interacts with trans-2-bromocyclohexanol to deprotonate the alcohol and produce the appropriate alkoxide ion. Trans-2-cyclohexanol and hydrobromic acid are created when the hydroxide ion displaces the bromine atom in trans-2-bromocyclohexanol.
It's important to note that the reaction of trans-2-bromocyclohexanol with NaOH requires an excess of NaOH to be completely deprotonate the alcohol, and in case there is not enough NaOH, the product may not be the major product, but a mixture of different products.
The specific mechanism of the reaction of trans-2-bromocyclohexanol with NaOH is called an elimination reaction. The reaction begins with the deprotonation of the alcohol by the hydroxide ion. This results in the formation of the alkoxide ion, which is a much better leaving group than the bromine atom.
