It's because the cavity doesn't lie exactly at the centre, rather it lies in quite upper side.
no
After he formation of morula(in cleavage),a number of changes occur which lead to blastulation.A cavity appears due to compact rearrangement of of cells in embryo within the upper half,now called blasocoel.The embryo now called blastula.The cells now move to new positions according to function they have to perform.
the frog is called when it pops out a frogspawn i love frogs yeah!
A large frog is called a bullfrog. Bullfrogs are known for their deep croaking calls and their robust bodies, making them one of the biggest frog species in North America.
An immature frog is often called a pollywog.
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.
no
Distribution of yolk cells.
The chick egg has much more yolk than the frog egg. A blastopore in frog egg and a premitive groove in chick egg both have the same basic function which is to mark the origin of gastrulation

A deformed frog is simply called a mutant.

The front half of the frog is called the Anterior.
because it is
