The segments of a tapeworm consisting primarily of eggs, which hang in bags as a long chain behind the head, are called scolexes
makkiz [27]

The answer is proglottids.

When tapeworm infect the intestine, it will attach a segment that consist of a part with many eggs called proglottids. The proglottids will constantly produce eggs. If the worm is removed but some of the proglottid leave behind, the infection would be recur, so it is important to remove all proglottid

I. two daughter nuclei are formed (telophase) II. centromeres separate (early anaphase) III. cytoplasm is divided (cytokinesis)
alex41 [277]

Answer:

The correct order would be - V, II, IV, I, III

Explanation:

Mitosis is one of the two types of cell division that occurs in an organism however they both take place in different types of cells. Mitosis is the process in which the genetic material or specifically chromosomes divide into two nuclei that are genetically identical to the parent cell. They also have a similar number of chromosomes.  

Mitosis division is completed in the four stages followed by cytokinesis in order which are prophase, metaphase, anaphase, telophase, and division of cell or cytokinesis.

Thus, the correct answer is - V, II, IV, I, III.

Which of the following are among the most common second messengers?
Anvisha [2.4K]

Answer:

4. calcium ion and cAMP

Explanation:

Second messengers are the intracellular chemicals that are produced for signal transduction and generation of cellular response when a water-soluble hormone binds to its cell surface receptors. Since water-soluble signaling molecules such as protein hormones cannot cross the cell membranes of their target cells, their binding to the respective receptors triggers the production of an intracellular second messenger. The most common second messenger molecules are cAMP and calcium ions. For example, protein hormones bind to their G-protein linked membrane receptors and trigger the synthesis of cAMP in their target cells.
