Is the degenerating blastocoel visible in the frog gastrula?
no
Why blastocoel of blastula of frog called excentric?
The blastocoel of the frog blastula is called eccentric because it is located closer to one pole of the blastula instead of being centrally located. This eccentric positioning is due to the unequal distribution of yolk in the frog egg, causing the blastocoel to be displaced towards the animal pole where there is less yolk.
What is the function of camouflage in the wild?
Camouflage is the process of blending into the background. It only works if the predator hunts by looking - animals who hunt by sound or smell are not fooled by camouflage! Many animals have color patterns which match the environment in which they live. If they freeze against this background, they blend in and are harder to see.

What is blastocoel?
A blastocoel is the fluid-filled cavity in the blastula.
Is the degenerating blastocoel visible in the frog gastrula?
no
What does a blastocoel develop into?
Definitive Yolk sac
What is the central cavity of a blastula called?
blastocoel
What is the cavity within the blastula called?
The central cavity within the blastula is called the blastocoel. It is filled with fluid and is surrounded by a layer of cells called the blastoderm.
What is a blastocoele?
A blastocoele is the fluid-filled cavity in the blastula.
The digestive tract develops from a central cavity located inside the?
The digestive tract develops from a central cavity called the blastocoel. During embryonic development, the blastocoel is surrounded by the endoderm, which eventually forms the lining of the digestive system. This process is known as gastrulation.
Why blastocoel of blastula of frog called excentric?
The blastocoel of the frog blastula is called eccentric because it is located closer to one pole of the blastula instead of being centrally located. This eccentric positioning is due to the unequal distribution of yolk in the frog egg, causing the blastocoel to be displaced towards the animal pole where there is less yolk.
How does the morula stage of sea star development differ from the blastula stage?
The blastula is a single-layered ball with a fluid-filled cavity called the BLASTOCOEL in the middle (which the morula stage lacks). --Side note: The morula is a ball of cells about the same size as the original zygote and the large number of embryonic cells of the morula arrange themselves into a blastula, with the blastocoel in the middle.
The major body space in arthropods is the A. coelom B. pseudocoelom C. hemocoel D. blastocoel E. pseudocoelom?
C. hemocoel
Compare the frogs blastula with that of a sea star?
The frog blastula is formed through holoblastic cleavage, resulting in a multicellular blastula with a fluid-filled cavity (blastocoel). In contrast, the sea star blastula is formed through radial holoblastic cleavage, leading to a solid blastula with no blastocoel. Additionally, the frog blastula undergoes gastrulation to form a gastrula with three germ layers, while the sea star blastula directly develops into a bipinnaria larva without gastrulation.
How many cell cell layers are found in a bastula?
A blastula typically consists of a single layer of cells called the blastoderm. This layer forms during early embryonic development and surrounds a fluid-filled cavity called the blastocoel.
