C. It is an incredibly long molecule with thousands of genes.
Hello!
The answer to your question is C.
Photosynthesis
Explanation:
Photosynthesis is a process carried out by green plants to convert water, carbon dioxide and minerals into oxygen and energy rich organic compounds in the presence of sunlight.
Here, it is given that
Food > Cellular respiration > Carbondioxide released
Food is the input and carbondioxide is the product of the process Cellular respiration.
Hence the complete model will be
Food > Cellular respiration > Carbondioxide released > Photosynthesis > Oxygen released + Food
Here carbondioxide is the input and food and oxygen are the products of the process photosynthesis.
~Hope this helps!~
Answer:
Answered below.
Explanation:
During the absorption of glucose in the small intestinal lumen, the following processes occur.
Sodium ions inside the small intestinal cells are moved into the interstitial fluid and into the blood by the sodium-potassium pump.
The resulting low sodium in the intracellular environment creates a concentration gradient that triggers the transportation of sodium ions from the intestinal lumen into the small intestinal cells or enterocytes, by a mechanism called facilitated diffusion. Facilitated diffusion means diffusion facilitated by a transport protein. This transport protein, called the the sodium-glucose cotransporter, transports sodium alongside with glucose into the cells.
After glucose has been transported into the cell,it is then moved through the basal and lateral membranes into the blood by another transport protein called GLUT2.
Answer:
Option B is likely originated from photosynthetic bacteria.
Explanation:
A) pellicle and contractile vacoule
B) Stigma and chloroplast (photosynthetic bacteria)
C) reservoir and flagellum
D) photoreceptor and Nucleolus
Euglena is a genus of single cell flagellate eukaryotes. Euglena have features of both animals and plants. Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. Euglena's chloroplasts evolved from a eukaryotic green alga. Thus, the intriguing similarities between Euglena and the plants have arisen of a secondary endosymbiosis. Molecular phylogenetic analysis support this hypothesis but this is not generally accepted. A stigma (red eyespot) is located near the base of the reservoir and this filters the light and focuses it on the paraflagellar body, and is involved in the phototaxis of this alga.
