Answer: Receives food that the duodenum have been digesting;
And then begins the absorption of major nutrients as well as Vitamin B12 and bile salts.
Explanation: The duodenum which is the first section of the small intestine is where most of the chemical digestion takes place as well as absorption of iron, enzymes are been secreted from the gall bladder, pancreas, liver et cetera into the duodenum to help breakdown the fat and protein as well as further break down the carbohydrates.
The food then goes through the jejunum and lleum where absorption of major nutrients as well as Vitamin B12 and bile salts into the blood stream begins.
Answer:
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published On the Origin of Species in 1859, including concepts which predated Darwin's theories. English biologist Thomas Henry Huxley coined the term Darwinism in April 1860.
Answer:
The best explanation for why tiny river has recently been experiencing increasing erosion of the sediment along its banks is increased runoff.
Explanation:
The main agents of soil erosion are wind, climate change, ice and water circulation.
Runoff is caused by precipitation, which is capable of produce erosion on the banks of a river, with some negative consequences for the environment.
Runoff depends on the flow of water, coming from rainfall, which moves across the surface of the soil, with great capacity for infiltration and erosion. In this case, runoff is the only possible cause of soil erosion
With respect to the other options:
<em>Decreased Slope
, decreased rainfall and increased vegetation are not factors related to the erosion in the bank of a river. </em>
