Answer:
<em><u>The right answer is "D".Transcription uses uracil.</u></em>
Explanation:
The genes carried by the DNA will be encoded in another form: messenger RNA, during a process called "transcription".
The DNA and RNA molecules are chemically very close, but the second has an extra oxygen (in red on the right of the letters) on the sugars (riboses) that make up its nucleotides (the DNA actually contains deoxyribose). In addition, the thymine (T) of DNA is replaced by uracil (U) in RNA.
Hope this help
Have a nice day!!
The answer is 8 because 4800 divided by 600 equals 8 so the right answer is d
Answer:
The correct answer is option A, that is, cytochrome c oxidase.
Explanation:
A sequence of complexes, which conduct electrons from electron donors to electron acceptors through redox reactions, that is, both oxidation and reduction reactions taking place simultaneously is termed as the electron transport chain. This conduction of electrons is further combined with the mediation of protons across a membrane.
Four membrane-bound complexes are present within the mitochondria, of these in complex IV or cytochrome c oxidase, the withdrawal of 4 electrons takes place from 4 molecules of cytochrome c, and is mediated towards the molecular oxygen, which further gives rise to 2 molecules of water. During the process, 8 H+ are withdrawn from the mitochondrial matrix, which contributes to the proton gradient.
The right answers are complete gut and one-way gut.
Food is ingested by the mouth, where it is chewed and then thrown into the esophagus during swallowing.
After, there is food in the stomach
Then there is digestive absorption of nutrients in the small intestine
After that, Waste disposal and reabsorption of water in the colon (large intestine)
And finally, stool passes through the rectum (anus), where it is stored before defecation, induced by a reflex mechanism.
