Answer:
The correct answer is seven seconds.
Explanation:
When an individual consumes an alcoholic beverage, about twenty percent of the alcohol gets captivated in the stomach and the rest eighty percent get absorbed in the small intestine. The rate of the absorption of alcohol relies upon many things, that is, the concentration of the alcohol in the beverage, the kind of drink, and that whether the stomach is full or empty as food slows down the absorption of alcohol.
After getting absorbed, the alcohol moves into the bloodstream and gets dissolved in the water of the blood. The blood mediates alcohol all through the body. From the blood, the alcohol then enters and gets dissolved in the water within each and every tissue of the body.
If one takes a whiskey shot and holds it on the tongue than that whiskey moves through the walls of the tongue, the esophagus and then eventually the stomach. However, a shot of whiskey can be detected in the arms when is consumed on an empty stomach, and It touches every prime section of the body within 2 minutes.

What would happen if a cell underwent mitosis, but did not go fully complete cytokinesis?
How does changing the proteins produced in a cell alter what an organism does?
Final answer:
Changing the proteins produced in a cell can alter what an organism does through modifications to the RNA or protein, as well as mutations in the DNA or RNA.
Explanation:
Changing the proteins produced in a cell can alter what an organism does through various mechanisms. For example, modifications to the RNA or protein can affect the amount, function, and stability of the protein. Mutations in the DNA or RNA can also cause a protein to be made incorrectly, resulting in a loss of protein function. This can be detrimental to the organism as proteins are responsible for orchestrating almost every cell function and influencing most of the traits displayed by multicellular organisms.
Which of the following best describes succession? A. The changes in species composition in a community over time as species colonize and area. B. The evolution of species through natural selection to becomes different species over time. C. All of these are good descriptions of succession. D. The reduction of biodiversity of an ecosystem over time.
Succession is a process which brings change in the composition of species in a community over a period of time. In this process a community undergoes change for the initial colonization of a new habitat. Succession begins with colonization of an area that has not been previously occupied by an ecological community. Succession continues till the climax community occupies that area.
Succession refers to the changes in species composition in a community over time. It can be primary or secondary, commencing with pioneer species in primary succession. The community eventually reaches an equilibrium state.
Explanation:The term 'succession' best describes option A, that is, the changes in species composition in a community over time as species colonize an area. Succession describes the sequential appearance and disappearance of species in a community over time. Two types of succession namely are primary succession and secondary succession. In primary succession, newly exposed or newly formed land is colonized by living things, often starting with pioneer species who have few soil requirements. Secondary succession occurs when part of an ecosystem is disturbed yet remnants of the previous community remain. As succession progresses, communities will gradually reach an equilibrium state, the composition of species within these communities changing over time until a more or less permanent community is established.

When atp releases some energy, it also releases inorganic phosphate. what happens to the inorganic phosphate in the cell?
When ATP releases energy, inorganic phosphate can be used in various cellular processes such as phosphorylation of other compounds or stored as glycogen.
Explanation:When ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins. In the case of inorganic phosphate, it can be used in various cellular processes such as phosphorylation of other compounds or stored as glycogen.
A radioactive tracer has a half life of 2 hours. How much of a 2500 g sample will be available after 24 hours?
A) 2.44 g
B) 1.22 g
C) 0.610 g
D) 0.31 g
Final answer:
Using the concept of half-life, we find that after 24 hours, which is 12 half-lives for a substance with a half-life of 2 hours, a 2500 g sample of a radioactive tracer will decay to 0.610 g.
Explanation:
The student is asking about the amount of a radioactive tracer remaining after a certain period, given its half-life. To calculate this, we apply the concept of half-life, which is the time required for half of the radioactive substance to decay. In this case, the half-life is 2 hours.
After 24 hours, which is 12 half-lives (24 hours ÷ 2 hours per half-life), the amount of substance remaining can be calculated as follows:
After 1 half-life (2 hours): 2500 g ÷ 2 = 1250 g
After 2 half-lives (4 hours): 1250 g ÷ 2 = 625 g
...
After 12 half-lives (24 hours): 2500 g ÷ (2^12) = 2500 g ÷ 4096 = 0.610 g
Therefore, the correct answer to the student's question is C) 0.610 g.

The human body contains roughly 100 trillion cells. approximately what percentage of those cells are independent microorganisms?
Approximately 90% of the cells in the human body are estimated to be independent microorganisms.
These microorganisms, collectively known as the human microbiota, include bacteria, viruses, fungi, and other microbes that reside in and on our bodies. They are primarily found in areas such as the skin, mouth, gastrointestinal tract, and reproductive organs.
The human microbiota plays important roles in digestion, immune function, metabolism, and overall health. It is worth noting that estimates of the exact percentage may vary slightly in different studies, but the general range is around 90%.
More recent research indicates that the number of human cells and microbial cells in the body may be roughly similar, although there is still some variability among individuals it is still challenging to provide an exact percentage.
Hence, we can say that almost 90% of cells are independent microorganism.

Starting with the smallest level of ecological organization and moving toward the highest, the order should go organism, __________. view available hint(s) starting with the smallest level of ecological organization and moving toward the highest, the order should go organism, __________.
Answer:
The correct answer will be option-organism→population→community→ecosystem→biosphere
Explanation:
Ecologists have tried to organize the ecosystem into levels which gave rise to the concept of ecological level of organization.
In an ecosystem, the ecological organisation move from simplicity to complexity in which the lowest level is an organism or species. When these similar organisms live together they form a population. A group of these population form a community of organism which forms an ecosystem in the biosphere.
Thus, the ecological organization will be organism→population→community→ecosystem→biosphere

A client with a history of opiate abuse asks the nurse, "why do i crave this stuff so much?" the nurse responds, knowing that the client's craving is a result of which factor?
Final answer:
The craving the client experiences is likely a result of psychological dependence on opiates, where the brain's reward system has been altered to create intense cravings. The development of tolerance and the use of rehabilitation methods including psychotherapy and medication can assist in overcoming addiction.
Explanation:
The client's craving for opiates is likely due to psychological dependence, which is an emotional, rather than physical, need for a drug. Clients with a history of opiate abuse develop this dependence because these drugs alter the brain's reward system, leading to intense drug cravings. To answer the client's question, the nurse should explain that craving opioids is a common effect of the psychological dependence that can develop after repeated use, and even after the physical withdrawal symptoms have resolved.
Over time, a person who uses opioids may develop tolerance, meaning they need higher doses of the drug to achieve the same effect, which further exacerbates the cycle of dependence and addiction. Withdrawal symptoms from opioids can include not only physical discomfort but also psychological distress like anxiety and depression. To treat addiction, rehabilitation may involve psychotherapy, support groups, and sometimes medications like methadone to help manage cravings and withdrawal symptoms.

The principal hormone secreted by the corpus luteum, which prepares the uterus for pregnancy,
The corpus luteum, a temporary endocrine structure in females, produces the hormone progesterone which is crucial for maintaining pregnancy.
Explanation:The principal hormone secreted by the corpus luteum, which prepares the uterus for pregnancy, is progesterone. The corpus luteum is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone, necessary to maintain a healthy pregnancy. Once the egg has been released from the follicle during ovulation, the remaining follicular structure is transformed into the corpus luteum. If a pregnancy occurs, the corpus luteum continues to produce progesterone, which helps maintain the pregnancy until the placenta is able to take over this function.
