Worrying too much about your appearance is a sign of which challenge to mental and emotional health?

Answer:

experimental

Explanation:

According to my research on different research methodology, I can say that based on the information provided within the question this is an example of experimental research. This refers to a research approach where you do not know what the results will be so the researcher creates a series of controlled tests in order to gather data and come to a certain conclusion.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

Automate the process with lab automation.

Wear proper protective equipment.

Sterilize equipment.

Check your water source.

Clean surfaces regularly.

Reduce the number of touches.

Use an air filter and laminar flow hood.

Stay organized.

Final answer:

Researchers use various techniques to reduce the possibility of contamination in scientific research. These include maintaining a sterile environment, practicing good laboratory hygiene, using physical barriers, and proper handling and storage of samples.

Explanation:

In scientific research, it is essential to minimize the possibility of contamination to ensure accurate and reliable results. Researchers employ various techniques to achieve this:

1. Maintaining a sterile environment: This involves using clean equipment, wearing gloves, and working in a laminar flow hood. Clean equipment helps prevent the introduction of contaminants, while gloves and laminar flow hoods create a controlled environment that minimizes the risk of airborne particles contaminating the samples.
2. Practicing good laboratory hygiene: Regularly cleaning work surfaces, properly disposing of waste, and following proper handwashing techniques are crucial to prevent cross-contamination. Good laboratory hygiene helps maintain a clean and safe working environment.
3. Using physical barriers: Protective clothing, such as lab coats and gloves, act as physical barriers between researchers and the samples. Containment systems, such as biosafety cabinets, provide an enclosed space to handle potentially hazardous materials, reducing the risk of contamination.
4. Proper handling and storage of samples: Using aseptic techniques, such as flame sterilization or alcohol swabbing, when handling samples helps prevent contamination. Storing samples and reagents at appropriate temperatures, such as refrigeration or freezing, can also minimize the growth of contaminants.

Our body needs all 5 nutrients - protein, carbohydrate, fat, vitamins and minerals. However, protein is the nutrient is needed for proper growth and development. Correct answer: C

Proteins are needed to build, maintain and repair muscle, blood, skin and bones and  other tissues and organs in the body.  The main sources of animal proteins are milk, fish, meat, cheese and eggs. Large amount of protein is needed for building new tissue in short period, such as during infancy, pregnancy or when mother is nourishing a child.

A balance of all the nutrients in diet is essential but the nutrient that is important for growth and development is protein. The correct answer is option c.

There are in all five nutrients proteins, fats, carbohydrates, vitamins and minerals. Sometimes water is included as the sixth nutrient. A balance of all is important for proper functioning of the human body.

Proteins are very important in human physiology, they act as structural elements within the cell such as actin, form the extracellular matrix (ECM) elements, act as signaling molecules, hormones etc.

As the growth occurs repairs and maintenance is required and this work is carried out by proteins. With growth an additional need for protein is created which is why it has to be taken externally through diet.

It is helpful to remember the central dogma, and remember that in execution the blueprint of our growth and development (DNA) is carried out by the formation of proteins.

Growth and development requires formation of new structures and completion of processes, a lot of which are undertaken by proteins. From structural elements  actin, tubulin, enzymes such as hexokinase, lysozyme, to chaperones that help folding of other proteins, proteins play an important role in growth and development.

For growth and development protein is required. Correct option is c.
