The bacterium Listeria monocytogenes is found in soft cheeses, unpasteurized milk, meat, and seafood and can bring about fever, headache, nausea, and vomiting.

Listeria monocytogenes (L. monocytogenes) is a type of pathogenic (disease-causing) bacteria that thrives in moist environments like soil, water, decaying animals and plants, and can even grow in food storage methods like refrigeration.

Listeriosis is a serious disease brought about by the microorganism Listeria monocytogenes. After consuming contaminated food, listeriosis is typically contracted. Pregnant women, infants, older adults, and people with compromised immune systems are the primary victims of the disease.

There are a number of different ways Listeria can get into people's bodies. Consuming contaminated food, such as contaminated vegetables or raw (unpasteurized) milk, is frequently the source of cases.

The type of scientist best qualified to perform genetic engineering to produce more productive seeds in agriculture would be a molecular biologist, the correct option is C.

Molecular biologists specialize in studying the structure, function, and interactions of molecules within biological systems, including DNA and genes. Genetic engineering involves manipulating the genetic material of organisms, which requires a deep understanding of molecular biology principles.

Molecular biologists have the expertise to identify and isolate specific genes responsible for desired traits in crop plants, such as increased productivity or resistance to pests or diseases. They can then modify or introduce these genes into target plants to achieve the desired outcomes, the correct option is C.

Two newly identified microorganisms are acetate  and cellular carbon.

What is acetate?

Acetic acid comes in salt or ester form as acetate. The most typical component of biosynthesis, including the production of fatty acids, is acetate. A proton is taken out of the carboxy group of acetic acid to produce acetate, according to the NCI Thesaurus (NCIt).

What is glucose?

Known also as glucose, blood sugar is the main sugar found in your blood. Your body uses it as its main source of energy, and it comes from the food you eat. The glucose in your blood is used as fuel by all of the cells in your body. Diabetes symptoms include excessively high blood sugar levels.

On transferring onto the media containing acetate  one strain survives that means the strain which survives can carry out glyoxylate cycle because glyoxylate cycle allows cell to utilize  two carbon compound such as acetate  to satisfy  cellular carbon requirement as a source when simple sugars such as fructose and glucose are absent.

Therefore, two newly identified microorganisms are acetate  and cellular carbon.

Fats and oil are more soluble than fatty acids because they have more carbon chains than fats and oil.

Lipids like fats and oil also known as triglycerides are soluble in organic solvents like petroleum ether and chloroform but are insoluble in water. They tend to come together to form a mass with each other in water.

Fatty acid on the other hand are less soluble than fats and oil because they contain more carbon hydrogen bonds than fats and oil and are non-polar bonds. Also unsaturated fatty acid has two hydrogen bonds removed from it which allows it to form a stronger double bond between two carbon atoms.

Capillary sphincter closure during internal or external bleeding is detrimental because it leads to waste products not being removed and nutrients not being delivered to the cells. (option b)

This is because capillary sphincters are circular muscular bands that regulate blood flow by opening and closing based on the tissue's metabolic needs. When capillary sphincters are closed, blood flow to the region decreases, thereby reducing the amount of oxygen and nutrients supplied to the surrounding cells. Capillary sphincter closure during internal or external bleeding, however, worsens the situation by depriving the cells of nutrients and oxygen.

The muscles and other tissues may become hypoxic as a result of this deficiency, leading to cell death and/or long-term damage. Blood flow is diverted to areas with higher oxygen demands, such as the heart and brain, during capillary sphincter closure. It's important to remember that the body's internal processes are inextricably linked. Even minor changes in blood flow or nutrient supply can have significant effects on the functioning of an organ or system.

Answer: I´m pretty sure it´s broad

Explanation:

Answer:base

Explanation:

The description provided refers to the organ system level of organization in the human body, where the heart, blood vessels, and lungs work together to deliver oxygen to the body's cells.

In the human body, the organization is hierarchical, with each level having its own unique characteristics and functions. At the highest level, we have the organism, which refers to the entire living being. Below that, we have the organ systems, which are groups of organs working together to perform specific functions.

The heart, blood vessels, and lungs are part of the cardiovascular system, which is responsible for circulating blood throughout the body. The heart pumps oxygenated blood from the lungs to the cells, while the blood vessels serve as the transportation network, delivering the blood to different tissues and organs. The lungs are responsible for oxygenating the blood and removing carbon dioxide.

This coordination and interaction between the heart, blood vessels, and lungs to deliver oxygen to the cells exemplify the organ system level of organization. The organ system level is an intermediate level between individual organs and the entire organism and represents the collaboration of different organs to perform a specific physiological function.

Answer:

whole numbers

Explanation:

Meristic traits are referred to as traits that are countable, hence the phenotypes are described by whole numbers instead of irrational, prime, complex or imaginary numbers. Meristics traits are usually associated with fishes, it is used to characterize different known species of fish or can also be employed in identifying unknown fish species. Meristic studies are mostly done on dead fishes than on living fishes

An example of a countable trait in fishes is the number of gill rakers. The identification of the number of gill rakers can be used in identifying the specie of fish.

Stronger stimuli are interpreted when the CNS receives more frequent action potentials The correct answer is (c).

Stronger stimuli lead to more frequent action potentials being generated and sent to the central nervous system (CNS), resulting in a greater perception of the stimulus.

When a sensory receptor detects a stimulus, it generates an action potential that travels along a sensory neuron to the CNS, where it is interpreted. The intensity of the stimulus is encoded by the frequency of the action potentials.

In general, the stronger the stimulus, the greater the frequency of action potentials generated by the sensory neuron, and the more intense the perception of the stimulus will be. Therefore, in this case, larger or smaller action potentials or less frequent action potentials would not lead to a stronger interpretation of the stimulus by the CNS. Hence, (c) is the right option.

The addition of a new taxon known as the domain was a significant change to the Linnaean system. A domain is a larger and more inclusive taxon than the kingdom. Most biologists agree that life on Earth is divided into three domains: Bacteria, Archaea, and Eukaryota.One reason for the need for revisions is that many new organisms have been discovered since Linnaeus' time. Another reason is that scientists began classifying organisms based on evolutionary relationships rather than solely on physical trait similarities.
