You need to refuel your PWC. When should you check for gas fumes?
A. before fueling
B. while fueling
C. after fueling and before starting the engine
D. after fueling and restarting the engine
Answer:
C. after fueling and before starting the engine
Explanation:
A personal watercraft (PWC) is popularly known as jet skis or water scooter which run over water as its name suggest and ride by a rider who either sits or stands on the PWC rather than sitting inside of.
PWC run on unleaded gasoline and premium gasoline. Gas fumes in PWC is required to check after fueling and before starting the engine because if the tank will overfilled, fuel can expand into the water or leakage can cause explosion as well. After fueling and just before staring the engine it is must to check for evidence of gas fumes and one is smelling gas fumes, the source need to repair immediately.
Hence, the correct option is C.

Answers
A considerable number of eosinophils can be seen in a sample of tissue from a wound. This would suggest that there were viruses present in the tissue.
A virus is a small, contagious organism that can only grow inside of living cells. Virus infections are possible in all living things, including plants, animals, and microorganisms like bacteria and archaea. More than 9,000 of the millions of virus species have been thoroughly documented since Dmitri Ivanovsky's 1892 publication identifying a non-bacterial disease infecting tobacco plants and Martinus Beijerinck's discovery of the tobacco mosaic virus in 1898.

Technically true for the sum of all water on the planet too, but fresh water gets renewed by cyclical processes in nature.

Why do teens tend to make riskier decisions than adults?
Answers
Brain Development: The brain undergoes extensive development and reorganization during adolescence, particularly in the prefrontal cortex, which is responsible for decision-making, impulse control, and weighing consequences. This region develops at a slower pace compared to the reward-seeking regions of the brain, such as the limbic system. As a result, teenagers may be more driven by immediate rewards and less inclined to consider long-term consequences.
Sensation Seeking: Adolescence is characterized by heightened sensation seeking and a desire for novel and exciting experiences. Teenagers often seek out new sensations and engage in risk-taking behaviors as a way to explore their own identity, gain independence, and test boundaries. The pursuit of thrills and excitement can overshadow the potential risks involved.
Social Influence: Peer influence plays a significant role during adolescence. Teenagers are highly attuned to social acceptance and approval, and they may engage in riskier behaviors to fit in, gain peer recognition, or conform to social norms within their peer group. The desire for social status and acceptance can override concerns about potential negative outcomes.
Incomplete Experience and Judgment: Compared to adults, teenagers have less life experience and exposure to various situations, making it more challenging for them to accurately assess risks and make informed decisions. They may lack the cognitive tools and judgment skills to fully evaluate the potential consequences of their actions.
Emotional Intensity: Adolescence is a time of heightened emotional intensity, with teenagers experiencing intense emotions and seeking ways to regulate them. Risk-taking behaviors can serve as a means to cope with or regulate these emotions, providing temporary excitement, distraction, or a sense of control

Describe the steps involve in cell fractionation
Answers
Cell fractionation is a laboratory technique used to separate cellular components based on their size, density, or other physical properties. This process allows researchers to isolate and study specific cellular organelles or molecules. The steps involved in cell fractionation are as follows:
1. Cell Preparation:
The first step is to prepare the cells for fractionation. This involves growing or culturing the cells in appropriate media, maintaining optimal conditions for cell viability, and ensuring they are in a healthy state. The cells can be derived from tissues, cell lines, or organisms depending on the experimental requirements.
2. Cell Disruption:
Once the cells are prepared, the next step is to disrupt their membranes and release the cellular contents. This can be achieved through various methods, including mechanical disruption (such as homogenization or grinding), enzymatic digestion, or sonication. The goal is to break open the cells and release the intracellular components while minimizing damage to the cellular structures.
3. Homogenization:
Homogenization involves further breaking down the disrupted cells to obtain a homogeneous cellular suspension. Mechanical methods like high-speed blending or passing the cell suspension through a narrow gauge needle can be used. This helps to ensure a uniform sample and facilitate subsequent fractionation steps.
4. Differential Centrifugation:
The cell homogenate is subjected to a series of centrifugation steps to separate different cellular components based on their sedimentation rates. The initial centrifugation is performed at low speed to remove cell debris and unbroken cells. The resulting supernatant, known as the crude fraction, contains a mixture of organelles, membranes, and cytoplasmic components.
5. Density Gradient Centrifugation:
To further separate and purify specific organelles or components, density gradient centrifugation is employed. This technique utilizes a density gradient medium, such as sucrose or cesium chloride, layered in a centrifuge tube. The cell fraction is carefully layered on top of the gradient and subjected to high-speed centrifugation. During centrifugation, particles sediment through the gradient based on their density, resulting in distinct bands or fractions containing specific organelles or components.
6. Fraction Collection:
After centrifugation, the fractions containing the desired cellular components are collected carefully. This can be done by carefully aspirating or extracting the specific bands or layers from the gradient using a syringe or pipette. The collected fractions are then processed further for analysis, such as protein quantification, enzymatic assays, electron microscopy, or other biochemical techniques.
7. Analysis and Characterization:
The collected fractions are analyzed using various techniques to identify and characterize the isolated cellular components. This may involve protein analysis using gel electrophoresis, immunoblotting, or mass spectrometry, as well as microscopy, enzyme activity assays, or functional studies to determine the biological properties of the fractions.
Answer:
Cell fractionation is a procedure for rupturing cells, separation and suspension of cell constituents in isotonic medium in order to study their structure, chemical composition and function. Cell fractionation involves 3 steps: Extraction, Homogenization and Centrifugation.
