wlad13 [49]

Answer:

Please see my answer below.

If you like my response you can mark it as brainliest.

If you have any doubts (no joke) you can reach out to me in the comments.

Explanation:

<em><u>The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.</u></em>

A simplified model of protein synthesis is shown here: How might this model be revised to show a more accurate depiction of prot
Nady [450]

Answer:

<em>The correct options are:</em>

<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>

<em>Between processes 1 and 2, the mRNA must be modified before leaving the  nucleus.</em>

Explanation:

For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.

Can you determine which instances reflect a valid experiment or conclusion? Check only those that are valid.
vagabundo [1.1K]

Answer:

Only options a reflects the instances with valid experiment or conclusion.

Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.

Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).

Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.

Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.

Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.
