Answer:

Steroid; is a component of eukaryotic membranes.

Explanation:

Cholesterol is one of the most important chemical synthesized by all the animals. The chemical formula of cholesterol is C27H46O. The cholesterol in solid state was first given by C27H46O.

Cholesterol is present in the plasma membrane and maintain its membrane fluidity. Cholesterol is an important structure of the plasma membrane and acts as a pre cursor for various hormone. The cholesterol is a type of sterol and a lipid.

Thus, the correct answer is option (1).

Based on what we discussed in class for each organism (unicellular vs metazoan), use no more than a few short sentences to specu
julsineya [31]

Answer:

Explanation:

The unicellular organisms basically classified into prokaryotes and eukaryotes. In case of bacteria the nucleus was completely absent but the replication and translation process were combined together. so there is no need of complexity. The genome is under control of one replication of origin i.e. the replication of DNA and translation for proteins synthesis takes place simultaneously and again no complexity. The organism is depend on these proteins and DNA for different purposes like fission, energy production etc.

If we think about Eukaryotes there is separate boundary for DNA and protein synthesis Nucleus and rest of cytoplasm with organelles. The complexity increases because of functional variations and functions occur at different times. So the whole genome replication is not needed every time and there are separate Origin of replications for segments of DNA (genes). Along with these there are non-functional DNA segments (introns functionally they won’t give proteins). To eliminate them there is a separate process after mRNA synthesis called post transcriptional modifications. After this protein synthesis takes place at cytoplasm. There is one more check point called post translation modification where protein modification (functional diversity) allocated. To adapt the changing environment, stress, reproduce and for any functions there is a wide diversity if we compare prokaryotes and eukaryotes.

During the cell cycle, A. DNA is replicated before mitosis begins. B. DNA is replicated once before mitosis and again before cyt
saw5 [17]

Answer:

The correct answer is A    DNA  is replicated before mitosis begins

Explanation:

DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.

       DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.

     DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.

Use the normal ecg trace below to determine how many seconds the trace represents as well as the heart rate.
mezya [45]
Attached is the image of the concerned ECG reading.

In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute. 

<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>

How does this sentence violate the principles of objectivity in writing a summary?
Mnenie [13.5K]
You didn't provide the sentence that is relevant in this case, however, generally if you would like to be objective in a sentence, you shouldn't include possible issues such as subjective thoughts, judgments, and similar things which have a negative impact on objectivity (and in reality destroy any remaining objectivity in a sentence).
