What is schistosity and how does it differ from slaty cleavage?
Schistosity refers to the parallel arrangement of mineral grains in a metamorphic rock, creating a visible foliation. Slaty cleavage, on the other hand, describes the highly defined parallel alignment of fine-grained minerals in a rock, resulting in a distinct splitting property. While both features involve foliation, schistosity typically exhibits coarser grains and is associated with higher grade metamorphic rocks, while slaty cleavage is characterized by its very fine-grained nature and is commonly found in lower grade metamorphic rocks like slate.
How does cytokinesis in animal cells differ from cyoknesis in plant cells?
In animal cells cytokinesis occurs when a cleavage furrow(a groove in the cell surface) forms around the cell. This furrow narrows the cell across the centre and eventually pinches it into two new cells.In plant cells a cleavage furrow does not form. Instead a cell plate forms across the equator of the cell. The cell plate consists of small vesicles which fuse to form two membranes across the cell. The new membranes fuse with the existing cell membranes and a new cell wall forms between them.

What are the difference between homologous organ and analogous organ?
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.
How is the blastocoele of a protostome similar to a deuterostome?
In both protostomes and deuterostomes, the blastocoele serves as a central cavity within the early embryonic structure, facilitating the organization of cells during development. While the specific developmental pathways differ—protostomes typically undergo spiral cleavage and form the mouth first, whereas deuterostomes exhibit radial cleavage and develop the anus first—the blastocoele itself plays a crucial role in providing space for cell movement and differentiation in both groups. Thus, despite their differences in developmental processes, the blastocoele functions similarly in both protostome and deuterostome embryos.
How is a blastopore used to indicate evolutionary relationships?
The blastopore is an indentation that forms during early embryonic development. Its fate can differ between species, with some having the blastopore develop into the mouth (protostomes) and others into the anus (deuterostomes). This distinction is used to infer evolutionary relationships between organisms, as species that share similar blastopore fates are considered more closely related.
How are adult body cells differ from embryonic stem cells?
adult body cells have a function where as embryonic stem cells have no set function as of that stage. now there are some adult stem cells and those have little to no difference than embryonic stem cells
How does the cleAvage of graphite differ from that of mica?
Cleavage in graphite occurs parallel to its basal plane, resulting in thin, planar sheets being formed. Mica, on the other hand, cleaves into thin, elastic sheets parallel to its basal plane due to its layered structure.
Why does cleavage occur?
Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
What is a embryonic structures?
Embryonic structures are early formations that develop during the early stages of an organism's growth and development. These structures serve as the foundation for the formation of different body parts and systems as the organism matures. Studying embryonic structures can provide insights into the evolutionary history and development of different species.
How does the cleavage of feldspar differ from the cleavage of mica?
Biotite (black mica) and muscovite (white mica) are both minerals that have perfect basal cleavage--one direction. It cleaves into thin sheets. Feldspars (albite, oligoclase, andesine, labradorite, bytownite, anorthite) have good cleavage in two directions at nearly right angles, poor in a third direction.
How does striated visceral muscles differ from striated cardiac muscles?
it has a different embryonic origin - it is neither cardiac nor skeletal muscle. it is often found in the head and neck.
Is cleavage sexy?
In one sense, cleavage is the hollow space between a woman's breasts revealed by a low neckline. Most women develop the appearance of cleavage although less endowed women can create and enhance cleavage with a variety of underwired and padded undergarments designed to push up and push together their breasts. The word "cleavage" in geology is used only to describe the morphology of fractures in minerals. Minerals have a cleavage, if they form flat, planal fractures along certain planes in their crystal lattice.
How does the structure and function of an adult somatic cell differ from that of an embryonic stem cell?
The structure and function of an adult somatic cell are specialized for carrying out specific tasks in the body, while embryonic stem cells are undifferentiated and have the potential to develop into any type of cell in the body. Adult somatic cells are more mature and have limited ability to divide and differentiate, whereas embryonic stem cells are pluripotent and can divide indefinitely and differentiate into any cell type.
How is mica and calcite be alike and how can they be different?
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral. Additionally, mica displays a pearly luster and tends to be softer than calcite, which has a vitreous luster and can scratch glass.
What is schistosity and how does it differ from slaty cleavage?
