Answer: Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Okay, to start off, the basic difference between prokaryotic cells and eukaryotic cells is prokaryotic cells are cells without a nucleus, and eukaryotic cells are cells that contain a nucleus.

So based off that information alone, you can answer #1. Cell A does not have a nucleus (big circle shape), while Cell B does. Therefore, Cell A is the prokaryotic cell.

As for #2, prokaryotic cells and eukaryotic cells DO have similarities despite their differences. For instance, they both have some of the same organelles, like the plasma membrane, ribosomes, cytoplasm, and DNA.

Finally for #3, two differences are that #1, prokaryotic cells have nucleoids while eukaryotic cells have a nucleus, and #2, prokaryotes have circular DNA while eukaryotes have linear DNA. 

Your best bet is finding a visual aid in a textbook or online to help you, so you can better identify organelles and eukaryotic/prokaryotic cells. Also, there are some cheesy videos out there on YouTube which I was forced to sit through in Bio class last year such as the Amoeba Sister's youtube channel which could help. Hope this helped!

A woman gets a report of abnormal cells from a routine pap test. She anxiously says to her spouse, "I have cancer. It probably h
Tanzania [10]

Answer:

To be sure, the patient need complementary studies.

Explanation:

In a pap test sometimes the result can be as "abnormal cells" but that does nt mean cancer directly. The doctor need to do a complementary study like a colposcopy to check if the cells are abnormal, and in which are is the damage.

Also the etiology could be due to the papiloma virus, that in most of the cases cause abnormal cells, that lead into cancer. But, in other situations, some other bacteria can be infected the reproductive system and have a false result due to other bacteria like yeast or Trichomonas.

Hope this is useful.

How does the wavelength of a G-note sound wave compare to the wavelength of an A-note sound wave? A. The G-note's wavelength is
ratelena [41]

Answer:

The G-note's wavelength is longer.

Explanation:

As we know that

The relationship between frequency, wavelength and the speed given as

Speed = Frequency x Wavelength

V= f λ

For constant speed, if wavelength increase then the frequency of the sound get reduce.

The wavelength of the A-note sound waves is smaller than the G -notes sound waves.

Therefore the answer of the given question will be A.

Assuming that transcription and translation both proceed from left to right, which is the correct orientation of the DNA templat
aleksklad [387]

The correct answer is:

DNA template 3'– ……… –5'

RNA transcript 5'– ……… –3'

Protein product H2N– ……. –COOH

In nucleic acids, DNA and RNA 5’ end refers to phosphate group attached to the 5′ carbon of the ribose ring, while 3’ end refers to the ribose -OH substituent. Nucleic acids can only be synthesized in the 5′-to-3′ direction, which means that the DNA template is 3’—5’. Translation of the protein by the ribosome will also proceed in a 5′ to 3′ direction, which means that the mRNA template is 3’—5’.

The protein during the synthesis is extend from its N terminus toward its C terminus.

A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed fo
Reptile [31]

When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.

Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
