1. Starting in the mouth, food follows a pathway through the digestive system. Describe how the mouth is involved in both mechan
ikadub [295]

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.

Glad to help!!!!

Compare and contrast the structures of DNA and RNA
katovenus [111]

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.

<h3>Meaning of speciation</h3>

Speciation can be defined as a process that births new species with different traits while they evolve.

Speciation occurs when extinction is eminent and most time in other to preserve that race they evolve into something new with new traits.

In conclusion, The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.

Can you list the types of organisms in order in which they would appear during primary succession?
nignag [31]

Answer:

Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.

The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.

These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.  

Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.

Thus, Lichens mosses → herbs→ shrubs →trees.
