I. Smooth muscle cells contain the contractile proteins actin (so-called "thin fibers") and myosin ("thick fibers") as components of their cytoplasmic structure. These function in concert ("sliding filament theory") to generate contraction in response to synaptic input from motor neurons.

II. Podocytes, which are cells within Bowman's capsule of the kidney that contain foot processes that interdigitate and wrap around glomerular capillaries creating slits through which filtrate passes. These slits are further covered by diaphragms containing various proteins that help ensure the passage of small molecules (e.g., urea) but the retention of large macromolecules (e.g., albumin or immune globins).

Define mass and explain how it affects an object's density.
Klio2033 [76]

Great Question! Mass is basically how heavy Something is. Most people confuse mass with weight but there very different from each other. Weight is the downward force something has because of gravity. Mass can be measured in a variety of units too. The second part of the question is how it affects density. It affects it because to find the density you need to be able to find the mass since the formula is Mass divided by volume. I hope this helped you understand a little bit more about mass. Have a great day!

How does the division of cell differ between plant and animal cells
lisov135 [29]
Plant and animal cells both undergo mitotic cell divisions. Their main difference is how they form the daughter cells during cytokinesis. During that stage, animal cells form furrow or cleavage that gives way to formation of daughter cells. Due to the existence of the rigid cell wall, plant cells don't form furrows.
