The cleavage in the chick is called discoidal because it is limited to the blastodisc.
EXPLANATION:
Post-fertilization changes in the chicken egg are caused by several mitotic divisions. The entire egg at a point of development is divided into two poles, the vegetal pole and the animal pole.
What else can I help you with?
One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
What property of minerals splits the mineral into pieces with uneven surfaces?
That property is called cleavage or fracture, depending on how the mineral breaks.
What type of fracture is it when a mineral splits evenly?
A mineral that splits evenly along flat surfaces is said to have a cleavage fracture. Cleavage occurs when a mineral breaks along weak atomic planes due to the internal atomic structure and bonding of the mineral.
Most minerals do not split apart evenly instead they have a characteristic type of?
Cleavage. Cleavage refers to the tendency of a mineral to break along planes of weakness, resulting in smooth, flat surfaces. The quality of cleavage can vary among different minerals, with some exhibiting perfect cleavage and others displaying no cleavage at all.
What type of cleavage results in a thin sheet of a mineral?
Perfect cleavage results in a thin sheet of a mineral. This occurs when the mineral breaks along flat, parallel planes.
The name for the type of cleavage in the mammalian embryo is called?
Rotational Cleavage
What is effect of yolk on cleavage?
Yolk affects cleavage by influencing the type and pattern of cell division during early embryonic development. In species with a high yolk content, such as birds and reptiles, cleavage is often discoidal and meroblastic, meaning that only a portion of the zygote undergoes division due to the large yolk mass. In contrast, organisms with little to no yolk, like many mammals, exhibit holoblastic cleavage, where the entire zygote divides uniformly. The presence and distribution of yolk ultimately determine the cleavage pattern and subsequent developmental processes.

What type of cleavage forms at the beginning of cell division?
The type of cleavage that forms at the beginning of cell division is called furrow or cytokinesis cleavage. This process involves the formation of a contractile ring made of actin and myosin filaments that pinches the cell membrane, resulting in the separation of the two daughter cells.
What property of minerals splits the mineral into pieces with uneven surfaces?
That property is called cleavage or fracture, depending on how the mineral breaks.
What type of cleavage do humans have?
Humans have holoblastic cleavage, which is a type of cleavage that occurs in eggs with little yolk. It involves complete division of the egg into smaller cells without the presence of a large yolk mass.
What is the Fracture type of pumice?
The fracture type of the Pumice rock is either jagged or splintery. The Pumice has both fracture and cleavage type.
What type of fracture is it when a mineral splits evenly?
A mineral that splits evenly along flat surfaces is said to have a cleavage fracture. Cleavage occurs when a mineral breaks along weak atomic planes due to the internal atomic structure and bonding of the mineral.
What is a determinate cleavage?
Determinate cleavage is a type of cleavage found in early embryonic development where the fate of each cell is fixed and determined early on. As cells divide, they become committed to specific developmental pathways, leading to the formation of distinct tissues and organs. This type of cleavage occurs in organisms with mosaic development.
