Viruses do not have any cells or metabolism. Viruses cannot reproduce on their own.

Most scientists do not consider viruses to be living.

Bacteria and fungi have cells, metabolism, and are able to reproduce.

Bacteria are unicellular microorganisms that can be found everywhere in the environment. Viruses are microorganisms that can only reproduce within the cells of a host organism.

The differences between viruses and bacteria include;  

  1. Viruses do not have any cell and are considered between living and non-living things, while bacteria have one cell (Unicellular) and are living organisms.
  2. Viruses are smaller in size (20-400 nm) when compared with bacteria (1000 nm).
  3. Viruses do not have a cell wall but a protein coat is present, while bacteria have a cell wall that is composed of peptidoglycan.
  4. Viruses require a living cell to reproduce, while bacteria can reproduce by itself.
  5. The DNA or RNA of viruses is enclosed inside a coat of protein, while that of bacteria floats freely in the cytoplasm within the cell.

Write a paragraph about your choice of organelle. Provide the answers to these questions within your paragraph:
Aloiza [94]

Answer:

I'm a eukaryotic, plant cell. I would be the central vacuole that stores excess water, food, and waste. There's only one of me in a plant cell. If I weren't in the cell, it would collapse or burst, because it well lose its turgor pressure. Moreover, the cell won't have enough space to store all the water and molecules needed for conducting photosynthesis. I resemble the stomach in a human body; a stomach stores food and water for later use.

Using a food label, explain what each section will tell you and why that would be important to, say, a long-distance runner.
IRINA_888 [86]
Nutrition labels diagram1 - Start with the serving information at the top.

This will tell you the size of a single serving and the total number of servings per container (package).

2 - Next, check total calories per serving and container.

Pay attention to the calories per serving and how many calories you’re really consuming if you eat the whole package. If you double the servings you eat, you double the calories and nutrients.

The next section of information on a nutrition label is about the amounts of specific nutrients in the product.

3 - Limit certain nutrients.

Check key nutrients and understand what you’re looking for. Not all fats are bad , and total sugars can include both natural and added sugars. Limit the amounts of added sugars , saturated fat and sodium you eat, and avoid trans fat. When choosing among different brands or similar products, compare labels and choose foods with less of these nutrients when possible..

4 - Get enough of the beneficial nutrients.

Make sure you get enough of the nutrients your body needs, such as: calcium, choline, dietary fiber, iron, magnesium, potassium, and vitamins A, C, D and E.*

5 - Understand % Daily Value.

The % Daily Value (DV) tells you the percentage of each nutrient in a single serving, in terms of the daily recommended amount. If you want to consume less of a nutrient (such as saturated fat or sodium), choose foods with a lower % DV (5 percent or less). If you want to consume more of a nutrient (such as fiber), choose foods with a higher % DV (20 percent or more).

Here are more tips for getting as much health information as possible from the Nutrition Facts label:

Remember that the information shown in the label is based on a diet of 2,000 calories a day. You may need less or more than 2,000 calories depending upon your age, gender, activity level, and whether you’re trying to lose, gain or maintain your weight.

When the Nutrition Facts label says a food contains “0 g” of trans fat, but includes “partially hydrogenated oil” in the ingredient list, it means the food contains some trans fat, but less than 0.5 grams per serving. So, if you eat more than one serving, you could end up eating too much trans fat.

The U.S. Food and Drug Administration (FDA) regulates the Nutrition Facts label seen on packaged foods and drinks. In 2016, the FDA released changes to the label to make it easier to see how many calories and added sugars are in a product and to make serving sizes more realistic. These changes are still being implemented throughout the food industry, so for now you may see the redesigned version shown here or the old original version.
