Answer:

Explanation:

The hemoglobin concentration is given in grams per deciliter (g/dL), and we want to find the mass of hemoglobin in milligrams (mg) per milliliter (mL) of blood.

To convert g/dL to mg/mL, we can use the following conversion factors:

1 g = 1000 mg (since "milli" means one-thousandth)

1 dL = 100 mL (since "deci" means one-tenth)

Therefore, 1 g/dL = (1000 mg/1 g) / (100 mL/1 dL) = 10 mg/mL.

So, to find the mass of hemoglobin in 4.50 mL of the patient's blood, we can multiply the hemoglobin concentration by the volume of blood:

mass of hemoglobin = (15.5 g/dL) x (10 mg/mL) x (4.50 mL) = 697.5 mg

Therefore, there are 697.5 milligrams of hemoglobin in every 4.50 mL of the patient's blood.

Answer:

Water is contaminated with animal waste

Explanation:

The presence of fecal coliform bacteria in a sample of river water suggests that the water is contaminated with animal waste. Thus, the correct option for this question is B.

The presence of fecal coliform in any sort of river or drinking water often indicates fecal contamination. This means that there is a greater risk that pathogens are present than if only total coliform bacteria are detected. E. coli is a sub-group of the fecal coliform group.

If coliform bacteria are present in your drinking water, your risk of contracting a water-borne illness is increased. This is because these bacteria are the most potent source of waterborne illness.  Although total coliforms can come from sources other than fecal matter, a positive total coliform sample should be considered an indication of pollution in your well.

Therefore, the presence of fecal coliform bacteria in a sample of river water suggests that the water is contaminated with animal waste. Thus, the correct option for this question is B.

The preparation of apple juice at high temperature produces a clearer juice​ because as the pulp temperature is raised to 55°C for the enzymatic depectinisation treatment.

Pectin, a part of the cell wall of fruits like apples and oranges, is broken down by the enzyme pectinase.

Commercially, pectinase is used to help with fruit juice extraction. It shouldn't be overly finely ground, agitated, or heated to more than 35 C in order to make a highly pressable mash (95 F). When using PECTINASES, the reaction and reaction time are normally 30 to 120 minutes, and the temperature range is kept mild, between 20 and 30 C. This serves in part to prevent complete protopectin hydrolysis. Protopectin binds the cells, and when it is hydrolyzed, the fruit tissue becomes more viscous, less pressable, and less robust. PECTINASE is a great addition to the mill, especially for apples with a soft texture. Pectin esterase and polygalacturonase make up a large portion of PECTINASES made for apple mashes (aka pectin glucosidase). These enzymes significantly lessen the pomace's viscosity and stickiness without influencing or lowering its protopectin content.

Pectinase releases the juice from within the cells by enzymatically dissolving the cell wall. The extracted juice is also clarified using pectinase.

hence this pectin dissolves the pectin and other compounds responsible for cloudy appearances and hence a clear juice is obtained.

Option A: Animals release carbon dioxide and water vapor as a by-product of cellular respiration.

Carbon dioxide and water are the byproducts of cellular respiration. These products are dispersed into the environment, where they affect the carbon and water cycles. Wherever carbon is delivered dissolved or suspended in flowing water, the two cycles directly interact.

Animals have a significant impact on the carbon and water cycles. Cellular respiration is the process by which animals obtain their energy. The process by which the food we eat is broken down and energy is turned into adenosine triphosphate is known as cellular respiration. In addition to this, animals use oxygen to perform cellular respiration and release carbon dioxide and water in to the environment as a by-product of this mechanism.

A good way to define wilderness is as a landscape not impacted by humans. This means that it is an area where human activities have not significantly altered or influenced the natural environment. Wilderness areas are typically characterized by their pristine and untouched condition, free from human development or modification.

Another way to define wilderness is as a landscape so diverse as to be nearly impenetrable. This refers to ecosystems that are rich in biodiversity and exhibit a high degree of complexity. These landscapes can be challenging to navigate or explore due to their dense vegetation, rugged terrain, or lack of human infrastructure.

It is important to note that wilderness is not an ecosystem in need of development. Instead, wilderness areas are often protected and preserved to maintain their natural state and ecological integrity. Development activities, such as building structures or extracting resources, are generally restricted or prohibited in these areas.

Similarly, wilderness is not an ecosystem in a state of dysfunction. While natural ecosystems can experience disturbances and fluctuations, wilderness areas are typically characterized by their resilience and ability to self-regulate. These ecosystems are often considered to be functioning in a natural and balanced way.

In summary, wilderness can be defined as a landscape not impacted by humans or as a diverse and complex ecosystem. It is important to recognize that wilderness areas are typically protected and preserved to maintain their natural state and ecological integrity. They are not in need of development or in a state of dysfunction. Wilderness areas play a crucial role in biodiversity conservation, scientific research, and providing opportunities for recreational activities that allow people to connect with nature.

Answer: A

Explanation:

Answer:

A

Explanation:

The Nernst potential of potassium at this point is -50 mV.

The Nernst potential for an ion is the potential across the cell membrane that exactly opposes the net diffusion of that ion through the membrane. The ratio between the concentrations of that particular ion on the two sides of the membrane, as seen above, determines the size of the Nernst potential.

The membrane potential at which an ionic species is in equilibrium is known as the Nernst potential.

The interior surface potential will rise after the transfer as the flow of K+ ions rises.

Calculation:

Nernst potential = RT/zF * ln( [K+]out / [K+]in )

Nernst potential = 8.314 J/mol * K * 300 K / (1 * 96485 C/mol) * ln( 100 mM / 10 mM )

Nernst potential = -50 mV

Answer:

See the explanation below. Thanks!

Explanation:

The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain \(pH\) value (different for each amino acid) nearly all the amino acid molecules exist as zwitter-ions. If acid is added to a solution containing the zwitter-ion, the carboxylate group captures a hydrogen (\(H^+\)) ion, and the amino acid becomes positively charged. If base is added, ion removal of the \(H^+\) ion from the amino group of the zwitter-ion produces a negatively charged amino acid. In both circumstances, the amino acid acts to maintain the pH of the system—that is, to remove the added acid \((H^+)\) or base \((OH^-)\) from solution.

Polysaccharide

Explanation:

The generation of excitation-contraction coupling involves the coordinated activation of several proteins and enzymes in order to produce muscle contraction. The correct option is B.

One of the key steps in this process is the release of calcium ions from the sarcoplasmic reticulum, which triggers a conformational change in troponin that allows for the binding of myosin to actin. Additionally, hydrolysis of ATP to ADP is required for the movement of myosin along actin filaments, generating force and shortening the muscle fiber.

However, the formation of cross-linkages between actin and myosin is actually a crucial event in the power stroke that generates force, and is therefore not excluded from the process of excitation-contraction coupling.
