sign the components on the following apoptotic pathway, which operates in human immune cells. a death signal is received when a molecule called fas binds its cell-surface receptor. the binding of many fas molecules to receptors causes receptor clustering. the intracellular regions of the receptors, when together, bind proteins called adaptor proteins. these in turn bind to inactive molecules of caspase-8, which become activated and then activate caspase-3. once activated, caspase-3 initiates apoptosis.
The apoptotic pathway in human immune cells is signed:
the binding of many Fas molecules to receptors causes receptor clustering. → the intracellular regions of the receptors, when together, bind proteins called adaptor proteins → a death signal is received when a molecule called Fas binds its cell-surface receptor → these in turn bind to inactive molecules of caspase-8, which become activated and then activate caspase-3. → once activated, caspase-3 initiates apoptosis.How does the apoptotic pathway work?There are two main pathways to apoptosis which are extrinsic and intrinsic. It is mediated by proteolytic enzymes known as capsules that trigger the death of cells by splitting proteins specific to the cytoplasm and the nucleus.
The Fas binds to Fas receptors located in cell surfaces and recruits an adaptor protein, FADD that contains a death domain.

Sandy beaches do not effectively absorb water.
What about impervious surfaces?Impervious surfaces are those that permit little or no infiltration of rainwater into the earth. Impervious surfaces are entirely man-made and, except from exposed natural rock cropping, constitute an artificial component of most ecosystems. Basically, water cannot soak naturally into the ground in constructed regions with large amounts of impermeable surfaces; instead, it rushes over the landscape, bringing pollution and biological contaminants into our rivers, harming fish, wildlife, and people. All hard surfaces, including paved roads, parking lots, roofs, and even densely compacted soils like sports fields, are referred to as "impervious surfaces." Residential roofs, public buildings, parking lots, commercial buildings, and bedrock near the soil's surface are a few examples of impermeable surfaces. Impervious surfaces are generally understood to include heavily compacted soils, concrete, asphalt, roofs, and other construction materials. Impervious surfaces include places like concrete patios, paved roads, driveways, sidewalks, and roofs because they are unable to absorb water.
