During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell. Mitosis has the following phases: prophase, metaphase, anaphase and telophase.
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.

Radioactive dating can determine the age of minerals and fossils in each layer of rock.
Explanation:
Radioactive dating is the most commonly used geological method to determine the age of rocks and fossils layered in the layers of rock on the basis of their natural radioactive decaying.
With the help of the known rate of radioactive decay of isotopes, different types of radiometric dating are done depending upon the material found in the rock layers, like uranium-lead dating or potassium-argon dating.
Radiocarbon dating helps to record organic content in rocks like bones, shells, etc. Age of fossils sediment over sedimentary rocks is determined by combining with the bracketing method.
<u>ANSWER:</u>
Diffusion is used by bacteria to transfer antibiotic resistance genes to other cells.
<u>EXPLANATION:</u>
- When bacteria becomes resistant to antibodies, it loses the ability to be inhibited.
- Diffusion in such case is used by bacteria to transfer the antibiotic genes to another species. This is because bacteria has the ability to replicate and transfer resistance by engulfing DNA from neighboring cells.
- Bacteria has the ability to take naked DNA encoding from similar species for the purpose of resistance and diffusion is the process that makes it possible.
