Answer:
When the lower esophageal sphincter is atrophied, a disease called achalasia occurs, in which there is no relaxation of the esophagus when the food is swallowed, it is difficult for the food to go down to the stomach. Some symptoms are that the food, once swallowed, can not pass and gets stuck.
Regurgitation, chest pain and weight reduction may also occur.
The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
Answer:
This question lacks options, however, it can be answered based on general understanding of forest layers.
The difference in photosynthetic rate is as a result of the amount of sunlight received by plants in the canopy and the forest floor.
Explanation:
Canopy of a forest refers to the collection of the crowns of trees found above the ground layer of a forest while the forest floor is the ground level of the forest. Plants that grow in the canopy are directly exposed to sunlight and receives most of the light from the sun while plants that grow in the forest floor are least exposed to sunlight as the crowns of the plants in the canopy covers/masks them.
Based on this, the rate at which the plants in the canopy layer photosynthesize will he higher than that of the plants in the forest floor because the amount of sunlight is a determinant of the photosynthetic rate.
Pretty sure its "<span>Breaks down glucose into two pyruvate molecules"
I have no Idea what FAD is and that one doesnt sound correct
It doesnt send it to the etc as far as I know
and ADP to ATP doesnt happen in glycolysis as far as I know
Glycolysis is one of my least favorite parts of Bio so Im not entirely sure.
