Answer;

A) island forms and mainland forms descended from common ancestors.

Explanation;

-Islands tend to host very distinct but limited sets or species; on a given island a spectacular collection of one related group of species would be present and thriving, but many entire families or even higher taxa would be completely absent.

-All the species on the islands and the nearest continent are closely related to one another, however, each species had a set of adaptations that suits it for a particular environment. This means that the island forms and mainland forms descended from common ancestors.

The __________ abuts the lumen of the alimentary canal and consists of epithelium
Misha Larkins [42]

Question is incomplete. Complete question is as follows:

The ____ abuts the lumen of the alimentary canal and consists of epithelium, lamina propria, and muscularis mucosae.

Answer:

Mucosa

Explanation:

Mucosa or mucosal membrane forms the lining of many cavities in the body like the alimentary canal and also covers many internal organs. It lines reproductive, digestive and respiratory system. In the gastrointestinal tract the mucosa is made of three layers: epithelium, lamina propria and muscularis mucosae.

The epithelium of mucosa is made of simple columnar epithelium cells. It consists of many types of cells like parietal cells (secrete HCL) and foveolar cells (secrete mucus). Lamina propria is a loose connective tissue present beneath the epithelium. It provides nutrition and support to epithelium. Muscularis mucosae has smooth muscle fibers which helps the glands on the surface to secrete their contents and also increase the contact between contents of lumen and epithelium.

How many total ATP are created with Cellular Respiration? What are the processes in which ATP is generated and how many ATP are
Setler79 [48]

Answer:

Explanation:

There is a total of 38 ATP produced. ATP is produced from 3 different steps. The first step is Glycolysis which produces 2 net ATP. Next, is the KREBS cycle (aka the Citric acid cycle) which also produces 2 ATP. The final step is the Electron Transport Chain, which produces 34 ATP.

Anabolic reactions require an input of energy, while catabolic reactions release energy. When talking about the metabolism, ATP is released through catabolic reactions. To grow and build muscles, for example, anabolic reactions are need (because you need food to gain muscle mass).

Anaerobic respiration means that NO OXYGEN is present while aerobic respiration takes place in the presence of oxygen. It is important to note that ONLY GLYCOLYSIS can occur during anaerobic respiration. Also, fermentation occurs during anaerobic respiration. There are two types of fermentation; lactic acid and "alcoholic". basically, lactic acid fermentation produces, well, lactic acid (which is used in yogurt and it's also the cramps you feel while running the mile in gym). Alcoholic fermentation is what is used to make alcohols like isopropanol or drinking alcohols like vodka.

Hope this helps :)

How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
