What are intercellular attachments?
Intercellular attachments are different kinds of attachments that keeps cells together. There are:Occluding junction form a barrier that isolates the basolateral surfaces and deeper the tissuses from the contents of the lumen.An Adhesion belt locks together the terminal webs of the neighboring cells, strengthening the apical region and preventing distortion and leakage at the occluding junction.Gap junction permits chemical communication that coordinates the activities of adjacent cells. Desomosomesprovides firm attachment between neighboring cells by interlocking their cytoskeletons.
What are the hairs on cells?
The cilia are tiny, hair-like structures found on the surfaces of cells. They are involved in various functions such as movement or sensing the environment.
Why is an epithelial cell the right cell for its job?
Epithelial cells form a monolayer with closely placed cells with tight junctions between that make them either impervious OR semi-permiable depending on the tissue. Hence, their design is ideally suited for ther function.
1 Moss plants are held in place by thread like structures called what?
The threadlike structures are called rhizoids.
What structures are used by prokaryotes for attaching to surfaces?
Prokaryotes use structures called pili or fimbriae to attach to surfaces. These are hair-like appendages that help prokaryotes adhere to various surfaces, including other cells or inanimate materials. Pili can also be involved in processes such as motility and DNA transfer between cells.

What types of cell junctions connect cells within tissues?
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
What are the functions of the horse's hoof?
The horse's hoof functions to support the horse's weight, absorb shock while moving, provide traction on different surfaces, and protect the sensitive structures inside the hoof, such as the coffin bone and the laminae.
Which vascular structures has the greatest combined surfaces area?
capillaries
What are the three main structural forms?
Persuasive, informative, and expressive.
A meniscus functions to cushion articulating surfaces of bones.?
true

What is the specialization at apical surfaces of epithelium?
The specialization at apical surfaces of epithelium includes microvilli, cilia, or stereocilia, which are involved in functions such as absorption, secretion, or movement of substances across the epithelial layer. These structures increase the surface area for better absorption and provide a way for the epithelial cells to interact with their environment.
Are ladders a ramp?
No, ladders are not ramps. Ladders are vertical structures used for climbing up or down, while ramps are sloped surfaces used for accessing different levels. They serve different purposes and are designed differently to accommodate their specific functions.
What are found on the outer surfaces of stromatolites?
Microbial mats and sediment layers are typically found on the outer surfaces of stromatolites. These structures are formed by the trapping and binding of sediment particles by microbial communities, resulting in layered structures visible on the surface.
What makes architecture minimalist?
Minimalism is the paring back to the essentials or minimums. In architecture, this involves removing anything applied or decorative, leaving plain smooth surfaces with unadorned or unemphasized connections and junctions.
