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:

Discuss why emerging diseases are appearing in industrialized countries.
Andrew [12]

Answer:

The correct answer is "For different reasons, including: pathogens developed resistance, people traveling much more frequently and practices of terrorism".

Explanation:

Emerging diseases are infectious diseases that are new to a region, or that remerge from a place that were believed to be eradicated. For different reasons emerging diseases are appearing in industrialized countries. One is that pathogens may have developed resistance to the treatments, as they may evolved naturally or it was driven by overuse of antibiotics. Other is that people are traveling much more frequently than in the past, which helps pathogens from distance places to reach industrialized areas. Also, terrorism practices is a cause of introducing pathogens deliberately to a new place.
