The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant.

It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time.

The walls of neighboring plant cells, cemented together to form the intact plant, are generally thicker, stronger, and, most important of all, more rigid than the extracellular matrix produced by animal cells.

In evolving relatively rigid walls, which can be up to many micrometers thick, early plant cells forfeited the ability to crawl about and adopted a sedentary life-style that has persisted in all present-day plants.

Therefore, The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant.

Answer:

Body systems. Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels,arteries and veins.

The history of science is also a history of people resisting new discoveries that conflict with conventional wisdom.

When Galileo promoted Copernicus’ theory that the Earth revolves around the sun – counter to church doctrine about the Earth being the center of the universe – he wound up condemned by the Roman Inquisition in 1633. Charles Darwin’s theory of evolution – that new species develop as a result of natural selection on inherited traits – ran into opposition because it contradicted long-held scientific, political and religious beliefs. Alfred Wegener’s 1912 proposal that Earth’s continents move relative to each other – the theory of continental drift – was rejected for decades, in part because scientists held fast to the traditional theories they’d spent careers developing.

These kinds of examples aren’t only historical, unfortunately. We’re used to hearing about how the general public can be dense about science. You might expect some portion of everyday folks to take their time coming around on truly groundbreaking ideas that run counter to what they’ve always thought.

But scientists, too, hold their own personal beliefs – by definition, based on old ways of thinking – that may be holding back the innovation that’s at the heart of science. And that’s a problem. It’s one thing for an average Joe to resist evolving scientific theories. It’s quite another if a scientist’s preconceived notions holds us back from discovering the new and unknown – whether that’s a cure for Zika or a cutting-edge technology to combat climate change.

Personal beliefs as publication roadblocks

Real scientific progress occurs when laboratory or field research is reported to the public. With luck, the finding is accepted and put into practice, cures are developed, social policies are instituted, educational practices are improved and so on.

This usually occurs though publication of the research in scientific journals. There’s an important step between the lab and publication that laypeople may not know about – the evaluation of the research by other scientists. These other scientists are peers of the researcher, typically working in a closely related area. This middle step is commonly referred to as peer review.

In a perfect world, peer review is supposed to determine if the study is solid, based on the quality of the research. It’s meant to be an unbiased evaluation of whether the findings should be reported via journal publication. This important step prevents sloppy research from reaching the public.

However, in the real world, scientists are human beings and are often biased. They let their own beliefs influence their peer reviews. For example, numerous reports indicate that scientists rate research more favorably if the findings agree with their prior beliefs. Worst of all, these prior beliefs often have nothing to do with science but are simply the scientists’ personal views.

‘But that’s counter to what I thought…’

How is this a problem for scientific innovation? Let’s look at how some personal beliefs could prevent innovative science from reaching the public.

Minorities aren’t good at STEM.” The stereotype that “women are not good at math” is commonly held – and also happens to be incorrect. If a scientist holds this personal belief, then he is likely to judge any research done by women in STEM (Science, Technology, Engineering and Mathematics) more negatively – not because of its quality, but because of his own personal belief.

For instance, some studies have shown that female STEM applicants in academia are judged more harshly than their male counterparts. Because of this gender bias, it may take a female STEM researcher more time and effort before her work reaches the public.

Some racial minorities face similar kinds of bias. For example, one study found that black applicants are less likely to receive research funding from the U.S. National Institutes of Health than equivalently qualified whites. That’s a major roadblock to these researchers advancing their work.

However, people often believe that comic books are just low-brow entertainment for kids. If a scientist holds this personal belief, then she’s likely to judge any psychology research using comic books more negatively. Because of this, scientists like me who focus on comic books may not be able to publish in the most popular psychology journals. As a result, fewer people will ever see this research.

The history of psychology supplies one example. Behaviorism was psychology’s dominant school of thought for the first part of the 20th century, relying on observed behavior to provide insights. Its devotees rejected new techniques for studying psychology. During behaviorism’s reign, any talk of internal processes of the mind was considered taboo. One of the pioneers of the subsequent cognitive revolution, George A. Miller, said “using ‘cognitive’ was an act of defiance.” Luckily for us, he was defiant and published one of the most highly cited papers in psychology.

The scientific endeavor requires belief. There would be no science if people didn't have faith in the objectivity of other scientists' work.

New techniques, new galaxies, new planets, and potentially even the existence of life on them are just a few of the previously unthinkable possibilities that science has made feasible. Further possibility lies in the future.

Scientism is a very odd word, but for reasons we will see, it is an important one. Despite being a relatively new term, it is connected to numerous other “isms” that have a long and violent history.

The moral standing of professors and mentors, the order and understanding of nature, and the compatibility of reason and truth.

Therefore, scientific discovery in today’s world that has been overshadowed by popular belief.

Reduced food intake this long after surgery may indicate the animals are in pain and distress. This statement is true about a reduced food intake in rodents 5 days after a vascular cannulation surgery.

Intravenous cannulation is the process of inserting a small plastic tube (a cannula) into a peripheral vein. The resulting venous access can be used to administer fluids, medication, and nutrition. Blood samples can be obtained from the cannula in some cases.

During cardiac surgery, a cardiac cannula is a tube inserted into a vein or artery. A venous cannula is used to administer or remove fluids, whereas an arterial cannula is used to secure access to an artery for purposes such as blood sampling or blood pressure monitoring. It is an invasive method for measuring blood pressure and mean arterial pressure that is more accurate than non-invasive methods.

Phenols and glycosides are pre-existing defense mechanisms in plants' immune systems. These compounds are part of the plant's chemical defense arsenal and are present in various tissues even before any attack or infection occurs.

Phenols are secondary metabolites found in plants that have antimicrobial and antioxidant properties. They contribute to the plant's defense against pathogens by inhibiting the growth and development of microorganisms. Phenols also play a role in wound healing and lignification, which strengthen the plant's cell walls.

Glycosides are another class of secondary metabolites found in plants that have diverse functions, including defense against herbivores and pathogens. Some glycosides act as toxic compounds when ingested by herbivores, while others can inhibit the growth of microorganisms or interfere with their feeding behavior.

Both phenols and glycosides are produced by plants as part of their constitutive defenses, meaning they are present at baseline levels even in the absence of stress or attack. However, their production can be further induced or enhanced in response to specific stimuli, such as pathogen invasion or herbivore feeding.

Option 2. "Diffusion moves carbon dioxide in the atmosphere to the oceans, and the sea plants use carbon dioxide for photosynthesis."

Explanation:

This statement describes two processes in the carbon cycle. First, carbon dioxide moves from the atmosphere to the oceans through diffusion. Once in the oceans, carbon dioxide can be taken up by sea plants during photosynthesis, in which carbon dioxide is used to make organic molecules like sugars. These organic molecules are then consumed by other organisms in the ocean, and the carbon is passed along the food chain. This process represents one path that carbon dioxide can take through the carbon cycle.

Bacterial intoxications differ from bacterial infections of the digestive system in that intoxications in having shorter incubation times. The correct option is a.

Foodborne sickness known as "food poisoning" or "bacterial food poisoning" is brought on by consuming food that has bacterial toxins in it already. Food contamination by bacteria can lead to the formation of poisons. when bacteria grow as a result of temperature and/or time misuse.

The location of the toxin production makes a difference. After being consumed, the microbial agent colonizes the gut and subsequently releases toxins that damage the host cells. When bacteria manufacture toxins in food before it is consumed, intoxication results.

The shorter incubation periods of bacterial intoxications set them apart from bacterial infections of the digestive system.

Therefore, choice a is the best one.

The Himalayan region is home to the yak, a type of cattle. They have a reputation for having long, shaggy hair, which is used to create many different textiles, including wool. Yak wool is popular because it is soft, warm, and long-lasting and is frequently used to manufacture clothes and blankets.

Camels are widely known for their capacity to survive in difficult desert situations, and their wool is a valuable resource in many parts of the world. Clothing, rugs, and other textiles are frequently made from camel wool because it is cosy and soft.

Goats are another typical source of wool, especially in warmer locations where other types of wool are less common. Depending on the breed of goat and the quality of the wool, the term "mohair" or "cashmere" is frequently used to describe the wool from goats. Cashmere is appreciated for its warmth and luxurious feel, while mohair is renowned for its softness, sheen, and insulating qualities.

Despite the fact that there are numerous dog breeds with long, shaggy hair, none of them actually produce true wool. Dog hair is not often used to produce textiles since it is formed of a different kind of fibre than wool. Although some dog hair can be spun into yarn and used for crafts, it is not regarded as a true wool and is not widely utilised for the manufacturing of textiles.
