Yes. There are many sample questions for the Indian Council of Medical Research (ICMR) Junior Research Fellowships (JRF) which you can find in the related link given below. You must have Adobe Acrobat Reader to view the questions.

No question is not there in the above mention Link's. This is totally incorrect answer.

The first heart sound "lub" is caused by the closing of the mitral and tricuspid valves during the beginning of systole (ventricular contraction). The closure of these valves creates vibrations in the surrounding fluid and tissues, resulting in the characteristic sound.

The defect of having a third chromosome 21 is known as Trisomy 21, which causes Down syndrome. This genetic condition leads to intellectual disabilities, characteristic facial features, and an increased risk of certain health issues.

There is no hormone that is secreted from the mouth. However, there is an enzyme amylase that is part of the digestive system.

Oxygen leaves the body through the process of respiration. During inhalation, oxygen is taken into the lungs and transferred to the bloodstream, where it is then distributed to cells in the body. As cells use oxygen for metabolic processes, carbon dioxide is produced and exchanged back through the bloodstream to the lungs, where it is exhaled out of the body.

The number of temporary tags you can get varies by state and jurisdiction. Generally, most states allow for one temporary tag per vehicle. However, some states may have restrictions on how many temporary tags can be issued for a particular vehicle within a certain time frame. It is best to check with your local Department of Motor Vehicles for specific regulations.

Balpam (also known as edible chalk) is not intended for human consumption and can cause health issues if ingested in large amounts. It may lead to digestive problems, constipation, and even blockages in the intestines. It is important to avoid consuming non-food items and seek medical help if you experience any adverse effects.

The Bronze Star Medal is an award presented for heroic or meritorious achievement or service not involving participation in aerial flight. The medal is suspended from a red ribbon with a narrow blue stripe down the middle of the ribbon. A Bronze BATTLE Star is worn upon the Campaign Ribbon of the Theater that the veteran served in. Each Bronze BATTLE Star indicates a campaign that the veteran participated in. When the veteran has earned five Bronze BATTLE Stars, the five are replaced by a single Silver BATTLE Star. My father served in six campaigns in the MTO & ETO, so on his ribbon there was a silver & a bronze campaign star. Richard V. Horrell WW 2 Connections.com

The Purple Heart was amended in 1942 to allow for those wounded or killed as a result of enemy action to receive the medal. This change expanded the eligibility criteria beyond those wounded in combat to include those injured or killed through hostile acts by an enemy.

During a fight or flight response, the release of stress hormones like adrenaline (epinephrine) triggers an increase in heart rate. This physiological response is designed to prepare the body for immediate action by supplying more oxygen and nutrients to the muscles and brain.

electrolysis is a scientific word. It means to split the water into two terms of chemistry. which H2O into H2+O. H equals to hydregen, and O equals to Oxygen. In GIN(Global Issues ?), a lot of scientists are interested in electrolysis. Because, if you eletrolysis the water, Hydregen appears out. So the hydregen can be the engine of the car, which uses the CO2, and breaks the environments down. That is what the GIN is learning about. And also, hydregen doesn't break the environment down, so that is keeping the environment green, and friendley.

The thin-walled priming chamber pump of the heart. Each of the two atria lies above the ventricle, separated by a one-way atrioventricular valve. The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.

Heartstrings, also known as chordae tendineae, are strong fibrous cords that attach the valves of the heart to the muscles in the heart wall. They help to prevent the valves from collapsing back into the heart chambers when they close, ensuring proper blood flow through the heart.

Because your body has to conserve its energy to use for keeping itself warm, it will shut down any functions that are not absolutely vital to life, and slow down those that are vital. Because there's not enough blood in in your body to keep you warm enough: hence slowing your vital organs down.

Ventilation is a process humans rely on to maintain high oxygen and low carbon dioxide concentrations at the gas exchange surface. The process that ventilates lungs is breathing. Humans ventilate the lung by negative pressure breathing

An activity ratio, such as asset turnover or inventory turnover, is typically used to measure how efficiently a company is utilizing its assets to generate revenue. These ratios help assess the company's operational efficiency and effectiveness.

VLDL (Very Low-Density Lipoprotein) is produced in the liver. It is one of the lipoproteins responsible for transporting triglycerides from the liver to peripheral tissues.

Assuming you know the difference between binary and decimal:

Binary:

1024K = 1MB

128MB * 1024KB = 131072KB (KB's in 128MB)

131072KB / 4 = 32768 (4KB's in 128MB)

Decimal:

1000K = 1MB

128MB * 1000KB = 128000KB (KB's in 128MB)

128000KB / 4 = 32000 (KB's in 128MB)

If you don't know the difference between binary and decimal, binary is exact values, decimal is the way things are marketed. (IE: A hard drive is marketed as 80GB when in reality you only get 78.125GB)

The vas deference is lined by pseudostratified columnar epithelium, supported by a basal lamina, a folded lamina propria, and a thick smooth muscle coat that is composed of a inner longitudinal, middle circular, and outer longitudinal smooth muscle layers.

Factors that can influence the MIP rate of measuring performance include the level of data accuracy, the appropriateness of key performance indicators (KPIs), the frequency of data collection and reporting, and the alignment of organizational goals with performance metrics. Additionally, the use of technology for data collection and analysis can also impact the MIP rate.

Palate is the correct answer!

The touch pad contains several layers of material. The top layer is the pad that you touch. Beneath it are layers (separated by very thin insulation) containing horizontal and vertical rows of electrodes that form a grid. Beneath these layers is a circuit board to which the electrode layers are connected. The layers with electrodes are charged with a constant alternating current (AC). As the finger approaches the electrode grid, the current is interrupted and the interruption is detected by the circuit board. The initial location where the finger touches the pad is registered so that subsequent finger movement will be related to that initial point.

See a doctor. If this is happening during or after exercise, this should not be a problem, however, if it just randomly happens while sitting, lying, or relaxing, it could be a case of heart palpitations. Heart palpitations are most of the time NOT life-threatening and will go away on their own. If they become more frequent or are accompanied by chest pain, shortness of breath, dizziness, or blacking out (fainting), you should consult your physician to rule out any underlying diseases.
