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.

What impacts do you think the burmese pythons might have on local ecosystem
Zigmanuir [339]
Introduction of burmese pythons to a local ecosystem can have grave consequences, as has been proven in Florida. Burmese pythons are skilled predators, and they are not easily killed by other animals. If introduced to a climate they can thrive in, they will start hunting local animals. With little to no predators capable of killing them, they will flourish because of plentiful food supply, and they will continue to increase in number. They will decrease the level of animals directly below them in the food chain, which will then increase the number of animals and plants that had previously been eaten by the python's new food. 

Basically, don't mess with food chains! :)

Explain how mitosis ensures genetic continuity from cell to cell in an organism
frosja888 [35]
<span>In comparison, mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>

The two cells formed at the end of meiosis I have chromosomes that are
Shkiper50 [21]

The right answer is C.

Meiosis and fertilization contribute to the stability of the species.

Meiosis ensures the passage of the diploid phase to the haploid phase. It follows a phase of DNA replication and consists of two successive divisions, the second is not preceded by a duplication of DNA. These two divisions lead, from a diploid mother cell (2n chromosomes), to four haploid daughter cells, the gametes (n chromosomes).

Meiosis and fertilization are at the origin of genetic mixing.

During meiosis, intra- and interchromosomal mixing occurs (inducing a genetic diversity between the daughter cells, and they are systematically different from their mother cell).

*Intrachromosomal mixing, or crossing-over recombination, takes place between paired homologous chromosomes during the prophase of the first meiosis division;

*Interchromosomal mixing is due to the independent migration of the homologous chromosomes of each pair during anaphase of the first division. It therefore concerns chromosomes reworked by the intrachromosomal mixing that preceded it.
