If the complex cholesterol- HRP would not be commercially available, use the knowledge you learnt and internet to determine an alternative way for detecting cholesterol.
Answer:
Classical chemical methods, enzymatic assays, gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS)
Explanation:
Classical chemical methods, enzymatic assays, gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS) are the alternate methods used for the detection of cholesterol. These methods are used when HRP would not be commercially available for the analysis or detection of cholesterol in the patient's body so these methods can be used for the purpose of detection of cholesterol.

Explanation:
Menstruation, the follicular phase, ovulation and the luteal phase are the four events or phases of the menstrual cycle. Luteinizing hormone, follicle-stimulating hormone, and the female sex hormones i.e. estrogen and progesterone are the types of hormones that controls the uterine cycle. Each event in the uterine cycle has its own significance in the female body.
Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.
Answer:
The correct answer is C
Explanation:
Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes).
g Cerebrospinal fluid formed in the lateral ventricles travels through the ________ to reach the third ventricle.
Answer: Interventricular foramen
Explanation:
The cerebrospinal fluid is a fluid that covers the brain and spinal cord. It circulates through the subarachnoid space, the cerebral ventricles and the ependymal canal. Several diseases alter its composition and its study usually detects meningeal infections, carcinomatosis and hemorrhages. Some of its functions are:
Hydropneumatic support against local pressure for the encephalon.Eliminates metabolites from the central nervous system.Protects the central nervous system from trauma.This fluid also fills the ventricles, which are large open structures deep within the brain and help keep the brain buoyant and cushioned. The lateral ventricles are the largest ventricles and connect to the third ventricle through the intraventricular foramen. This third ventricle is a narrow, medial cavity located between the diencephalic masses. Then, the interventricular foramina are channels that connect with the ventricles of the lateral walls and with the third ventricle, at the level of the midline of the brain. Like these channels, they allow cerebrospinal fluid to circulate through the rest of the ventricular system of the brain. The walls of the foramina also contain choroid plexuses, responsible for the production of cerebrospinal fluid, which continue in both the lateral ventricles and the third ventricle. After reaching the third ventricle, the cerebrospinal fluid travels through the median aperture into the subarachnoid space at the base of the brain.

Most carbohydrates manufactured in leaves and other photosynthetic parts are transported through the phloem to the rest of the plant by the process of translocation. osmosis. transpiration. receptor-mediated transport. turgor pressure.
Answer:
Translocation
Explanation:
Translocation is the movement of sugar that is produced by the source( i.e the part of plants where sugar is produced for other plant parts which could be leaves) to the sinks( i.e the active growing parts of plants where sugar is been deposited for use) where it is used up.
Translocation is done through the phloem tissue to sinks. Sinks could include leaves, fruits, shoots, young developing seeds, tubers and stems.
Translocation is done through the pressure flow model where concentration of sugar that is high at the source creates a low solute potential which helps water movement into the phloem from the adjacent xylem. This movement creates a high pressure potential in the phloem that produce the movement of phloem sap by bulk flow from source to sink.
The density of protists living in the hay infusion is ______________ than the regular pond water.
a. significantly lesser
b. lesser
c. about the same
d. greater
e. significantly greater
Answer:
a. significantly lesser
Explanation:
The density of protists living in the hay infusion is significantly lesser than the regular pond water because protists likes to live in aquatic or any water bodies. Some protists float on the surface of the water making their own food like plants by using the process of photosynthesis. Aquatic environments are ideal environment for protists, which have cilia and flagella that allows them to move in the water in search of food..

Which of the following is not a characteristic of pioneer species ?
They facilitate environmental change, making an environment more habitable for other species
They remain in an environment,even as more competitive species arrive
They tolerate a wide range of conditions
They are capable of colonizing a barren environment
Answer:
They remain in an environment,even as more competitive species arrive
Explanation:
Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.
Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:
- They facilitate environmental change, making an environment more habitable for other species.
- They tolerate a wide range of environmental conditions.
- They are capable of colonizing a barren environment, as in primary succession.
However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
Besides oxygen exchange, the respiratory system also functions to eliminate (Click to select) . Too much of this gas can cause a(n) (Click to select) in blood pH, compromising homeostasis.
Answer: Carbon dioxide, decrease
Explanation:
Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water. Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.
In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.

When the belt is moving at a high speed, 350 pills can be coated per hour. How many minutes would it take to coat all the pills in this batch at a high speed?
Answer:
6 pills are coated in one minute time.
Explanation:
There are 350 pills can be coated in 60 minutes due to high speed of belt movement which means that 6 pills are coated in one minute time period so if there are 60 pills so the belt takes 10 minutes to complete the coating of the pills. If there are 200 pills to be coated then we used the equation i.e.
6 pills -------- 1 minute
200 -------- x
By cross multiplication we get,
6x = 200 x 1
x = 200 / 6
x = 33.3 minutes
This means that in 33 minutes the belt can coated 200 pills.
