Answer:

<h2>As transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location,  post-transcriptional processing in eukaryotes. </h2>

Explanation:

The transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location and can be co-translation.

As, in eukaryotes, the transcription occurs in the nucleus and then this transcript have to move in the cytoplasm to translation, so before reaching in the cytoplasm, various modifications occur in this transcript known as post transcriptional modification or processing ( include 5' capping, 3' poly-adenylation and RNA splicing).

As, in prokaryotes, both transcription and translation occur at same place so there is no time for modification for transcript because translation starts as the transcription is still going on.

What is the purpose of each organism being able to carry out either cellular respiration or photosynthesis?
dalvyx [7]

Photosynthesis takes in sunlight and carbon dioxide, along with water and nutrients, so the plant can make energy. That energy is used for cell growth and repair, producing seeds, etc. The plant will exhale oxygen as a byproduct of photosynthesis.

Similarly, cellular respiration is also used to create energy for the host organism. However, the cells take in oxygen along with something like complex sugars (ie the stuff you eat) and use those components to form energy for the cell. The energy for human cells is useful for cell growth and repair, nerve impulses, muscle contractions, etc. Basically anything you can think of that the human body needs to do on a regular basis, it requires energy to do so. A byproduct of cellular respiration is carbon dioxide, which is exhaled out to the environment. The plant will then absorb the CO2 to keep the cycle going.

In short, both processes are used to make energy for the cell. The differences is what the inputs for each process require. Photosynthesis takes in sunlight, water, and carbon dioxide (and other plant nutrients), and exhales oxygen. Cellular respiration takes in oxygen and complex sugars (from plant material or other animals) and exhales carbon dioxide.

raketka [301]
Its elevation is 400 meters (1,312 feet) below sea level. However, if depth were measured from the ocean floor, the Challenger Deep in the Pacific Ocean would be the lowest place on Earth. It measures 11,034 meters (36,200 feet) below sea level.

The nurse has administered a client's first scheduled dose of amoxicillin. what subsequent client report should prompt the nurse
Alexeev081 [22]

Amoxicillin is a broad-spectrum antibiotic widely used for certain bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a fairly strong drug, and it can elicit an allergy to patients even to those who had used the drug before and did not experienced any untoward problems. If the patient had symptoms such as difficulty in breathing, itching, and untoward swelling or lump in the throat when receiving treatment with penicillins like amoxicillin, sulbactam, ampicillin, methicillin, or penicillin G, the nurse should discontinue giving amoxicillin and report to the doctor right away.
