Osmosis requires energy

True
Or
False

Answers

Answer:

Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

how to write a narrative story?​

Answers

Answer:

Start with action or dialogue.

Ask a question or set of questions.

Describe the setting so readers can imagine it.

Give background information that will interest readers.

Introduce yourself to readers in a surprising way.

Explanation:

Answer:

Narrative essays/stories are often anecdotal, experiential, and personal—allowing students to express themselves in a creative and, quite often, moving ways. So, in short, it's an essay about your life with details, events, etc.

Explanation:

Narrative essays/stories should include:

an introduction, plot, characters, setting, climax, and conclusion.must have a purpose; think of this as the thesis of your story.the essay should be written from a clear point of view; essays to be written from the standpoint of the author (you); however, this is not the sole perspective to be considered. Creativity in narrative essays oftentimes manifests itself in the form of authorial perspective. narrative essays are effective when the language is carefully, particularly, and artfully chosen. Use specific language to evoke specific emotions and senses in the reader. the use of the first person pronoun ‘I’ is welcomed; though it is welcomed it is not necessary—nor should it be overused for lack of clearer diction.have a clear introduction that sets the tone for the remainder of the essay. Do not leave the reader guessing about the purpose of your narrative; you are in control of the essay, so guide it where you desire (just make sure your audience can follow your lead).

I hope that this helps you! I know it was a lot to read, but it's worth it. Have a nice night! :D

Although the liver and the pancreas are not part of the digestive tract, they are important to the process of digestion because: a. Secretions they produce help to digest food b. They absorb nutrients into the bloodstream c. They eliminate wastes from the body d. All of the above

Answers

Answer:

The correct answer is - d. all of the above.

Explanation:

The liver and pancreas are not part of the digestive tract but they play a very major role in the process of digestion. The liver and pancreas both produce and secretes the enzymes and bile to breakdown the food into nutrients. Bile digests the fat while enzymes of the pancreas break down protein, carbohydrates, and fats.

The liver helps in absorbing the fats and some vitamins and minerals to the bloodstream from the nutrient from digested food. They also help in the removal of toxins and wastes from the digested food or the waste products of breaking down into nutrients through the feces or filtered from the blood by the kidneys.

Considering ethical questions is part of a marine scientist’s job. Part of being ethical is doing your homework and exploring all sides of an issue. Choose a current ethical issue in marine science, such as the use of genetically modified organisms (GMOs), conditions in fish farms, or another topic your instructor approves. Find two perspectives supporting one side of the ethical issue and two supporting the other. Be sure to use reliable sources, such as university web sites or newspaper/magazine articles. Create an outline with at least five points for each side. Then write a brief paragraph explaining what you believe an ethical choice around this issue is. Remember, ethical problems are difficult because both sides have valid points. Be sure to consider and discuss at least one point you think is valid from the side that you disagree with in your conclusion as you explain why your choice is the ethical one. Also, include a list of sources that you used. Two is the minimum for each point of view.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.

What are genetically modified organisms?

Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:

Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.

Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.

Therefore, use of GMO's is profitable as well as hazardous for the environment.

please help this is due at 3pm

Answers

1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.

2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.

The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus

Explanation:

The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

what is antigen?

The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.

Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
