Solvents that are used to extract the lipids from homogenized tissue samples and subsequent separation of the lipids from the proteins and sugars present are methanol and chloroform.

Lipids are extracted using solvent-based techniques. In some cases, solvents are subjected directly into cell pellets, but in other cases, solvents are employed during disruptions of cell.

Lipids are insoluble in polar solvents like water but highly soluble in non-polar or weakly polar organic solvents like ether, chloroform, benzene, and acetone.

The Bligh and Dyer method is a widely practiced methods for lipid extraction. It is very similar to the Folch method, but differs in solvent/solvent and solvent/tissue ratios.

Answer:

The solubility of gases such as oxygen and nitrogen depends upon the ocean water's temperature and salinity. As the temperature of the ocean water increases, the solubility of these gases decreases. The solubility of carbon dioxide is greater than the other gases because of its ability to react with ocean water.

During endurance training, a cardiac adaptation contributes to augmented venous return and increased end-diastolic volume.

Endurance training involves repetitive and prolonged physical activity that challenges the cardiovascular system. Over time, this type of training induces specific adaptations in the heart, known as cardiac adaptations. These adaptations include increased stroke volume, improved cardiac contractility, and enhanced left ventricular compliance.

The increased stroke volume leads to augmented venous return, meaning that more blood returns to the heart during each cardiac cycle. Consequently, the end-diastolic volume, which represents the amount of blood in the ventricles just before contraction, is increased. These adaptations enable the heart to pump more blood with each beat, improving overall cardiovascular function and endurance performance.

The structure in the membrane that causes plasma membranes to resist freezing is the presence of phospholipids with unsaturated fatty acid tails.

Unsaturated fatty acids contain double bonds between carbon atoms, which introduce kinks in the fatty acid tails.

These kinks prevent the fatty acid chains from packing tightly together, increasing the fluidity of the membrane.

As a result, the membrane remains flexible even at lower temperatures, reducing the likelihood of freezing. In contrast, membranes with saturated fatty acid tails lack these kinks and tend to be more rigid, making them more susceptible to freezing at lower temperatures.

Explanation: At a maximum potential magnification of 1 nanometer, TEMs are the most powerful microscopes. TEMs produce high-resolution, two-dimensional images, allowing for a wide range of educational, science and industry applications.

Mark brainliest pls

scientist use a transmission electron microscope (TEM) instead of a compound microscope to view a tissue sample, the TEM will produce an image with a higher resolution. Thus option 1 is correct.

A microscope is an instrument which produces large images of tiny  objects and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope has  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base is used to support  and carries microscopic illuminators and Arms  which connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are used to view, magnify, and produce an image from a specimen placed and the various pars are Eyepiece or ocular situated at the top of the microscope with standard magnification is 10X, Eyepiece Tube carries the eyepiece just above the objective lens.

(a) The probability of a randomly chosen person having hemophilia is 0.000105.

(b) The probability that a given person with hemophilia is male is approximately 1.9.

(a) Probability that a randomly chosen person has hemophilia:

Haemophilia can affect both males and females, but we need to find the probability for both. Hence,

the probability of having hemophilia = probability that a randomly chosen person is male × probability that a male has hemophilia + probability that a randomly chosen person is female × probability that a female has hemophilia

Probability of having hemophilia in males = 2/10,000 = 0.0002

Probability of having hemophilia in females = 1/100,000 = 0.00001

Probability of a randomly chosen person is male = 0.5

Probability of a randomly chosen person is female = 0.5

Probability of having hemophilia = 0.5 × 0.0002 + 0.5 × 0.00001 = 0.000105

(b) Probability that a given person with haemophilia is a man:

From (a), we know that the probability of having hemophilia is 0.000105. Therefore, the probability that a given person with hemophilia is male is:

probability that a given person with haemophilia is a man = probability that a male has hemophilia/ probability of having hemophilia = 0.0002/0.000105 = 1.9048≈1.9 (approximately).

Several factors can decrease the affinity of hemoglobin for oxygen. These include an increase in temperature, a decrease in pH (acidity), an increase in carbon dioxide concentration, and the presence of certain substances such as 2,3-bisphosphoglycerate (BPG) or hydrogen ions.

One factor that decreases the affinity of hemoglobin for oxygen is an increase in temperature. Higher temperatures can cause hemoglobin to undergo structural changes, reducing its ability to bind with oxygen. Additionally, a decrease in pH, resulting in increased acidity, can lower the affinity of hemoglobin for oxygen. When pH decreases, the concentration of hydrogen ions increases, leading to the formation of additional bonds that stabilize the deoxygenated form of hemoglobin.

An increase in carbon dioxide (CO2) concentration can also decrease the affinity of hemoglobin for oxygen. Carbon dioxide can bind to hemoglobin and form a compound called carbaminohemoglobin, which stabilizes the deoxygenated form of hemoglobin and reduces its ability to bind oxygen. Moreover, the presence of 2,3-bisphosphoglycerate (BPG) can decrease the affinity of hemoglobin for oxygen. BPG binds to hemoglobin and stabilizes its deoxygenated form, promoting the release of oxygen to tissues. This effect is particularly important in red blood cells, where BPG levels are regulated to match metabolic demands.

In summary, several factors can decrease the affinity of hemoglobin for oxygen. These include an increase in temperature, a decrease in pH, an increase in carbon dioxide concentration, and the presence of substances such as BPG or hydrogen ions. Understanding these factors is crucial in comprehending how oxygen is transported and released by hemoglobin in different physiological conditions.

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.

Hill Equation

The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.

Hill coefficient

It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,

Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.
