Maria and her brother like to go fishing at the lake on Saturdays. They wondered if fish were more likely to bite at one time of

day than another. They decided to try an experiment over the next two Saturdays:
On the first Saturday, it was hot and sunny, and they went fishing in the morning. Maria and her brother caught five fish. On the second Saturday, it was overcast and cool, and they went fishing in the afternoon. They only caught three fish this time.

Should they conclude that fish bite better in the morning? Select the best answer and explanation below.

Answer:

No. They will need to repeat their experiment several times, since the weather and times were different both days.

Explanation:

When a scientific experiment is conducted, one independent variable shall be changed in each experiment at a time so that the results of the experiment are authentic and we can easily determine which independent variable caused a change in the dependent variable.

If more than one independent variable is changed in the same experiment, then it will be difficult to interpret that which variable caused the change.

<u><em>Similarly, Maria and her brother need to repeat their experiment several times with just changing one variable at a time. </em></u>

During pregnancy, a cell undergoes what appears to be a normal mitotic nuclear division. However, two daughter cells with 2n-1 a
dem82 [27]

Answer:

c. Two sister chromatids did not separate into the proper daughter cells during anaphase.

Explanation:

The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.

However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).
