Explanation:

such as, bread, milk or cheese, brussel sprouts or a salad, cantelope or strawberries, and a trail mix.

These days, when terms like “carbohydrates,” “fiber,” “fructose,” and “omega-3 fatty acids” are becoming commonplace, it seems like a rather simple concept.

What are the good and balanced meal include in meal?

Scientific study has significantly increased our understanding of human nutrition over the past few decades, yet this may now make a balanced diet appear much more challenging than it once did.

Despite cultural differences, food is always categorized in accordance with the primary purposes of its essential nutrients. The majority of foods are used for one of three purposes, which are: energy, growth and repair, or maintaining normal metabolic function.

Foods can be further divided into up to eight groups, depending on how detailed we want to be. Because of this, national dietary recommendations may differ globally in terms of the foods consumed, but generally speak, nutrient requirements are very similar.

Therefore, Grain, dairy, vegetables, fruits, and proteins are thus important. Brussel sprouts or a salad, cantaloupe or strawberries, cheese, bread, milk, and trail mix are a few examples.

Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.

The rate of cellular respiration is generally high in athletes. This is because they require more energy for running and other physical activities. So, their body derives energy faster than the normal healthy body of an individual.

Therefore, the cellular respiration level of an athlete will be higher than the normal healthy cellular respiration level. Thus, the correct option for this question is A.

I believe it would be either an laceration or an avulsion. But more or less an laceration but if you want to decide for yourself an laceration is a deep cut of tearing of the skin.

I believe it would be an avulsion due to the fact it states it sliced his lateral aspect up to his knee.
