What is the difference between ultramafic and ultrabasic?

As adjectives the difference between ultrabasic and ultramafic. is that ultrabasic is (geology) ultramafic while ultramafic is (geology) describing igneous rocks that contain magnesium and iron and only a very small amount of silica, such as are found in the earth’s mantle.

Is frog egg telolecithal?

The frog is an amphibian which possesses telolecithal eggs. In telolecithal eggs the amount of yolk is concentrated in the one half of the egg to form the vegetative pole of the egg and thus makes polarity along the axis of yolk distribution.

What is the difference between Isolecithal and telolecithal eggs?

If an uneven distribution of egg yolk is observed, it is referred to as a Telolecithal egg. If the egg yolk is concentrated to the center and a thin peripheral cytoplasm is observed, those eggs are referred to as Centrolecithal eggs. This is the difference between telolecithal and centrolecithal egg.
