3. Describe the benefits and drawbacks of experiments in a laboratory compared to experiments done in a
labwork [276]

Answer:

Benefits:

In  a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.

Drawbacks:

Ina  laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.

Which structure is perforated with pores to allow material to move in and out of the nucleus?.
erastovalidia [21]

The nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

Every cell in the body has a nucleus, except for mature erythrocytes (red blood cells). While some cells contain more than one nucleus such as skeletal muscle and some other cells contain several nuclei.

The nuclear envelope surrounds the nucleus. i. e. largest organelle of the cell. It has a similar structure to that of

the plasma membrane. But the nuclear envelope contains tiny pores that allow a few substances to pass between it and outside the cytoplasm, i.e. the cell contents excluding the nucleus.

Therefore, the nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

To know more about the nucleus, refer to the below link:
