Answer:

The correct answer is option a. "True".

Explanation:

Bufo marinus is the world's largest toad, it is native from South and Central America but it has been introduced to islands in Oceania and the Caribbean. Bufo marinus rapidly flipps its tongue to catch its prey for eating and defensive purposes. Bufo marinus has its tongue attached at the anterior part of the buccal cavity, while posterior margin of the tongue lies freely. This morphology allows Bufo marinus to make the quick movement needed to catch its prey.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi

Naya [18.7K]

Answer:

Granulosa cells

Explanation:

Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).

The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:

Primordial follicle

Primary follicle

Secondary follicle and

De Graaf follicles (This is the one shown in the image)

Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of granulous cells. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.

The oocyte at this point gets surrounded by zona pellucida and corona radiata .

The follicular antro (The highlighted structure) separates the oocyte from the externally located granulosa cells or follicular cells.

What information would you need to know in order to make an accurate classification of these organisms?

77julia77 [94]

Answer:

Following information are needed to classify an organism.

1. Unicellular or multicellular : First we have to see that from how many cells the body of organisms formed.

2. Composition of cell wall: Secondly we have to see the cell wall composition.

3. Prokaryotic or eukaryotic cell: We have to see the nucleus of organisms, if it has nucleus we can say that it is a eukaryotic cell.

4. Mode of nutrition: Mode of nutrition means is the organisms is autotroph or heterotroph.

If they have similarities, so it is placed in one group. If not so it is placed in different group or kingdom.
