A standard contains a known amount of a substance. If u are performing an experiment you will use a sample with a known concentration to create a standard curve (a straight line). Positive and negative controls are measured against the standard curve to show the expected results if the sample u will be testing is positive or negative.

Can anyone give me the answers to the blanks please !

Answer:

all animals need to eat food to get energy to live. But in order to use food they have to break it down in a process called digestion. And so, all animals have a group of connected organs called the digestive system.

In humans, the process of digestion begins in the mouth where food is chewed into small pieces by the teeth. The tongue helps by moving these pieces around. These pieces are covered by saliva or spit. The saliva makes the food slippery so that it is easier to swallow. It also helps break down the food.

Once the food is swallowed it passes through the esophagus which is like a gate that sends food into the stomach and air into our lungs. The food travels down the esophagus.

In your opinion, how does healthy eating help people be responsible and/or have good relationships with others?

stiv31 [10]

In my opinion, healthy eating people impact others in a positive way. I think so because they have an effect on their relationship with others. You are most likely to be more motivated to do other things when eating healthy rather unhealthy. Someone seeing your eating habits and disapprove of your actions may likely have a disgust look on their face. Although having some junk foods are okay, it is not good to intake many, as it is not good for your health.
