any one of a group of substances released from the ends of nerve cells when they are stimulated; they cross to the adjacent cell and cause it to be excited or inhibited.
Neurotransmitter is one of a group of substances released from the ends of nerve cells when they are stimulated; they cross to the adjacent cell and cause it to be excited or inhibited.
The body cannot function without neurotransmitters, which are chemical messengers. Their responsibility is to transmit chemical signals, also known as "messages," from one neuron (nerve cell) to the subsequent target cell. Another nerve cell, a cell of the muscle, or a cell of a gland may be the next target cell.
By moving across cells and binding to particular receptors on recipient cells, neurotransmitters send messages. Different receptors are the sites where neurotransmitters bind. One such instance is the attachment of dopamine molecules to dopamine receptors. They operate upon the target cells when they attach, causing a reaction.

Pinker provided evidence of deaf children who did not acquire language in the same way as hearing children, yet they still exhibited the same cognitive abilities as hearing children. This suggests that language does not entirely determine one's thoughts and perceptions of the world. However, Pinker also acknowledged that language can still have some influence on cognition and behavior, but it is not a deterministic factor.

From simplest to most complicated, how are multicellular organisms organized?.
Multicellular organisms are complex structures made up of various cells that work together to perform different functions. The organization of multicellular organisms can be divided into different levels.
At the simplest level, multicellular organisms are organized into cells that are grouped together to form tissues. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, connective tissue, or nervous tissue tissues are then organized into organs, which are structures made up of two or more tissues that work together to perform a specific function. Examples of organs include the heart, lungs, and liver organs are further organized into organ systems, which are groups of organs that work together to perform a specific task. For instance, the digestive system is made up of organs such as the stomach, intestines, and liver, which work together to digest and absorb nutrients from food.
Finally, all the organ systems of an organism are integrated into a whole, resulting in a fully functioning organism. Thus, the organization of multicellular organisms can be understood as a hierarchical system, from cells to tissues, organs, organ systems, and the entire organism itself.

in a population of 10,000 individuals, where 3600 are mm, 1600 are mm, and 4800 are mm, what are the frequencies of the m alleles and the m alleles?
To determine the frequencies of the M and m alleles in this population, we need to use the Hardy-Weinberg equation. This equation states that the frequency of the dominant allele (M) plus the frequency of the recessive allele (m) must equal 1, and that the frequencies of the three possible genotypes (MM, Mm, and mm) must also add up to 1.
First, we can calculate the frequencies of the three genotypes:
- MM = (3600/10000) x (3599/9999) = 0.1296
- Mm = 2 x (3600/10000) x (4800/9999) = 0.4608
- mm = (4800/10000) x (4799/9999) = 0.4096
Note that we use the formula n(n-1) / 2N(N-1) to calculate the probability of two individuals randomly mating and producing a particular genotype.
Next, we can calculate the frequency of the M allele by adding up the frequencies of the MM and Mm genotypes:
- M = 0.1296 + 0.4608/2 = 0.3600
Finally, we can calculate the frequency of the m allele by subtracting the frequency of the M allele from 1:
- m = 1 - 0.3600 = 0.6400
Therefore, the frequency of the M allele is 0.3600 and the frequency of the m allele is 0.6400 in this population of 10,000 individuals.

In what order do waste products pass through the urinary system to be excreted? place the following structures in the correct order.
The order in which waste products pass through the urinary system to be excreted is as follows: kidneys, ureters, bladder, and urethra.
The urinary system plays a crucial role in eliminating waste products from the body. To understand the order in which waste products pass through the urinary system, it is important to know the different structures involved in the process. These structures include the kidneys, ureters, bladder, and urethra.
The first step in the process is filtration, which occurs in the kidneys. Here, blood is filtered, and waste products such as urea, creatinine, and excess water are removed. The filtered blood is then returned to the body.
The next step is the transport of urine from the kidneys to the bladder. This is achieved through the ureters, which are tubes that connect the kidneys to the bladder. The urine is moved along the ureters by peristalsis, which is the rhythmic contraction of muscles in the ureter walls.
Once the urine reaches the bladder, it is stored until it is ready to be excreted from the body. This storage period can vary, depending on the amount of urine produced and the capacity of the bladder.
Finally, the urine is excreted through the urethra, which is a tube that connects the bladder to the outside of the body. The urethra is longer in men tan in women, which explains why men generally take longer to urinate.

An important structure for blood pressure regulation is the arterial baroreceptor.
Arterial baroreceptors are specialized nerve endings located in the walls of certain arteries, such as the carotid sinus and aortic arch. These receptors detect changes in blood pressure and transmit signals to the brainstem, which then adjusts the body's autonomic responses to maintain blood pressure within a normal range.
When blood pressure increases, arterial baroreceptors are stretched and send signals to the brainstem, which responds by decreasing sympathetic nervous system activity and increasing parasympathetic nervous system activity. This leads to a decrease in heart rate and dilation of blood vessels, resulting in a decrease in blood pressure.
Conversely, when blood pressure decreases, arterial baroreceptors are less stretched and send signals to the brainstem, which responds by increasing sympathetic nervous system activity and decreasing parasympathetic nervous system activity.

if blood thyroid hormone levels drop, what cascade of events increases thyroid hormone levels? put the following stages in order, beginning at the top with low thyroid hormone levels.
When T3 and T4 levels fall below the normal range, the hypothalamus releases thyroid regulating hormone (TRH), which in turn stimulates the pituitary gland to release thyroid stimulating hormone (TSH). TSH then acts on the thyroid gland to stimulate the production of additional hormones and raise blood levels.
Thyroid hormone egulation begins in the hypothalamus. Thyrotropin-releasing hormone (TRH) is released by the hypothalamus into the anterior pituitary gland's hypothalamic-hypophyseal portal system. Thyrotropin cells in the anterior pituitary are stimulated by TRH to generate thyroid-stimulating hormone (TSH).
Thyroxine (T4) is released by the thyroid into the bloodstream, where it undergoes a process known as de-iodination before being converted to triiodothyronine (T3) by specific cells in your body. This is because cells with receptors for thyroid hormone's effects are more adept at using T3 than T4.

A deletion mutation in the leader sequence of the trp operon removes the two tryptophan codons that are involved in attenuation. Predict the effect of this mutation on the expression of the trp structural genes in E. coli cells grown in media that lacks tryptophan. The trp structural genes will have decreased expression because the mRNA will adopt the terminator configuration. The ribosome will fail to recognize the trp structural gene mRNAs. The repressor protein R will be bound to the operator locus O. The trp structural genes will have increased expression because the mRNA will adopt the anti-terminator configuration.
The deletion mutation in the leader sequence of the trp operon will result in decreased expression of the trp structural genes in E. coli cells grown in media lacking tryptophan.
First, let's break down the terms. The trp operon is a set of genes in E. coli that are involved in the synthesis of the amino acid tryptophan. The leader sequence is a region at the beginning of the operon that regulates the expression of the trp structural genes by controlling transcription termination. Attenuation is a regulatory mechanism that allows the cell to adjust the expression of the trp structural genes in response to the availability of tryptophan.
Now, let's consider the effect of the deletion mutation in the leader sequence that removes the two tryptophan codons involved in attenuation. In the absence of tryptophan, the cell normally produces a short mRNA transcript that adopts a terminator configuration, which stops transcription of the trp structural genes. However, attenuation allows the cell to bypass this termination signal if tryptophan is present in the environment.
Without the tryptophan codons in the leader sequence, the mRNA will always adopt the terminator configuration, regardless of the presence of tryptophan. This means that transcription of the trp structural genes will be significantly reduced, since the mRNA will be terminated before the ribosome can complete translation.
Furthermore, the ribosome may fail to recognize the trp structural gene mRNAs, since they will have a different configuration than normal. This could lead to decreased translation efficiency and further reduction in expression of the trp structural genes.
Finally, the repressor protein R will still be bound to the operator locus O, since the mutation only affects the leader sequence. This means that the repressor will continue to block transcription of the trp operon unless tryptophan is added to the media.
In conclusion, the deletion mutation in the leader sequence of the trp operon will result in decreased expression of the trp structural genes in E. coli cells grown in media lacking tryptophan.

Which statement about the daughter cells following mitosis and cytokinesis is correct?.
After mitosis and cytokinesis, the daughter cells are genetically identical to each other and to the parent cell.
This is because mitosis is a process of cell division in which the parent cell divides into two identical daughter cells that have the same genetic information as the parent cell.
During mitosis, the replicated chromosomes line up in the middle of the cell and are pulled apart by the spindle fibers, resulting in two identical sets of chromosomes, one for each daughter cell.
After the chromosomes have been separated, the cell undergoes cytokinesis, which is the division of the cytoplasm to form two distinct daughter cells.
As a result of these processes, the daughter cells inherit an identical set of chromosomes and genetic information as the parent cell. This means that they have the same genes and genetic code, and are therefore genetically identical to each other and to the parent cell.
