Explanation:
1) Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.
2) The daily values are reference amounts (expressed in grams, milligrams, or micrograms) of nutrients to consume or not to exceed each day. The %DV helps you determine if a seving of food is high or low in a nutrient.
3) If a food has a daily value of 5% or less of a nutrient, it is considered to be low in that nutrient.
A food is a good source of a nutrient if the percent daily value is between 10% and 19%, If the food has 20% or more of the daily value, it is considered an excellent source of that nutrient.
4) As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
5) During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.

Answer:
Light takes 499.0 seconds to travel from sun to earth.
Explanation:
Answer:
Complex organisms evolved from more simple organisms
Explanation:
<em>Fossil records support the fact that complex organisms evolved from more simple organisms.</em>
<u>Fossils are remains of organisms that have been naturally preserved in rock forms. </u>
The study of fossilized remains of organisms has enabled scientists to establish the fact that earlier organisms are simple types and more complex organisms arose from them through a gradual process of change, otherwise known as evolution. Carbon dating of fossils enables scientists to establish the year the organism existed.
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
Answer:
- 9 out of 16 have gray fur and black eyes
- 3 out of 16 have gray fur and red eyes
- 3 out of 16 have white fur and black eyes
- 1 out of 16 have white fur and red eyes
Explanation:
Based on the image attached to this question, the question involves two genes. One coding for fur color and the other for eyes color. The alleles for gray fur (G) and black eyes (B) are dominant over the alleles for white fur (g) and red eyes (b).
Please find attached to this answer an image containing a completion punnet square using the gametes illustrated. According to the punnet square in the image, the following proportions of offsprings were obtained:
- 9 out of 16 have gray fur and black eyes (G_B_)
- 3 out of 16 have gray fur and red eyes (G_bb)
- 3 out of 16 have white fur and black eyes (ggB_)
- 1 out of 16 have white fur and red eyes (ggbb)
