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.

A) single loop
Fish have a two-chambered heart in which a single-loop circulatory pattern takes blood from the heart to the gills and then to the body.
Answer:
The conclusion that cuckolder are able to discriminate kin from non kin
Explanation:
From the above question, researchers carried out tests on the two types of fish (males cuckolder and parental males) to see if they can identify kin and non kin from the offsprings, using a null test.
But the test for cuckolder was rejected by the researchers for the cuckolder so they can't say cuckolder can indentify between kins and non kins, they didn't pass the test so it should be concluded that cuckolder can't identify between kin and non kin, instead of concluding they can identify them, that is the wrong conclusion.
