The rhynchocoel is a ________.

Biology
1 answer:
Anastasy [175]3 years ago
5 0

Answer:

fluid-filled cavity

Explanation:

Rhynchocoel is a fluid-filled tubular cavity present in the organisms of the phylum Nemertea. This cavity lies above the intestines of these organisms in the lower body.

Nemertea is a phylum composed of worms that can be found in shallow water.

These worms have already been classified as a branch of the Flatworms (such as Planarians), with which they are often confused. But recent embryological and molecular evidence points to a phylogenetic relationship with mollusks and annelids. They remind the Flatworms to be non-segmented flat worms. But unlike these, they have a complete bowel with mouth and anus, and a closed vascular system. The article on Planarians can be accessed here.

The chytrid fungus Batrachochytrium dendrobatidis is colonizing frogs across the globe causing massive mortality and even pushin
Elanso [62]

Answer:

Parasitism

Explanation:

Batrachochytrium dendrobatidis is a parasitic chytrid fungus which is responsible for the declining population of amphibians in the rain forests of Panama and Australia.

The fungus grows on the keratinized layer of epidermis on amphibian skin and makes a thick covering of fungus on the amphibian's skin. So as amphibian's skin helps them to maintain the proper osmotic balance in the body so when a thick fungus grows on their skin they are not able to maintain the correct osmotic balance in their body which leads to amphibian death.

So as Batrachochytrium dendrobatidis is a parasitic fungus and gets its nutrition from the frog body and do not kill frog immediately as in predation therefore this relationship can be considered as parasitism.

Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.
