Categorize each statement as an example of adhesion, communication, or differentiation. Statement During animal development, proliferating cells become organized into sheets of cells called epithelia. Cadherins play and essential role in maintaining the integrity of these sheets in a process known as: Complex multicellular organisms rely on signaling molecules synthesized by one cell to bind to receptors on the surface of a second cell to regulate gene expression. This type of interaction between two different cells is a form of: The human body contains 200 distinct cell types, yet each cell contains the same genome. The process by which each cell adopts a specific fate is known as: 100 Answer Bank Category

WRITE ABOUT A THEME: ORGANIZATION The properties oflife emerge at the biological level of the cell. The highly regulated process of apoptosis is not simply the destruction of acell; it is also an emergent property. Write a short essay (about100–150 words) that briefly explains the role of apoptosis inthe development and proper functioning of an animal, and describe how this form of programmed cell death is a process thatemerges from the orderly integration of signaling pathways.
A brain scan of an epileptic patient shows that the patient has clusters of neuronal cell bodies positioned in posterior periventricular zọne. A likely cause of this mislocalization could be a mutation in some repulsive guidance molecules in the extracellular matrix. a mutation in the Sonic Hedgehog factor which inactivates its function. O a mutation in the reelin protein at the marginal zone during development. O a defect in neuroepithelial cell mitotic process. a mutation in an astrocytes plasma membrane protein.
Muscle cells differ from nerve cells mainly because they express different genes contain different genes use different genetic codes have unique ribosomes have different chromosomes Meristematic tissue cells in plants are most similar to which kind of cells in animals? Somite cells Ectodermal cells Embryonic stem cells Mesodermal cells If a developing insect embryo was mechanically agitated in order to evenly redistribute cytoplasmic eterminants throughout the embryo, then the embryo would develop normally but at a faster rate of cell growth and differentiation resulting insect would be missing structures that typically develop in the absence of cytoplasmic eterminants embryo would develop normally due to cues from induction signaling cytoplasmic determinants would convert to induction molecules and diffuse out of the embryo most daughter cells would fail to properly divide

Early in their development, tunicates (sea squirts) have 8 cells. Ultimately these 8 cells will give rise to all the tissue types in their bodies. Design and explain an experiment through which you could determine whether the specification of these 8 cells to specific body parts is cell autonomous or conditional.
