What can dried blood tell an expert?

Biology

siniylev [52]2 years ago

Blood dries over time. How quickly this happens depends on the surface on which the blood landed, how much blood the spatter contains, and the heat and humidity at the crime scene, but as a rule the outer edges of the stain dry first. Consequently, after the interior portion flakes off or is smeared by an object, a dry blood spatter can skeletonize, that is, leave behind a ring similar in appearance (if not color) to a water ring on a coffee table. Patterns of drying help analysts determine how long an assault went on, detect whether it took place all at once or in stages, and nail down possible crime scene contamination. Clotting patterns in blood provide similar information and can help nail down the time factor if analysts arrive at the scene before blood can dry. Clotting begins within 3 to 15 minutes, but actual times vary by amount, surface type and environment. Mixed levels of clotting can indicate that multiple blows or gunshots occurred over time

When growing, as a cell gets bigger, what happens to its surface area to volume ratio?
marysya [2.9K]

<u>Answer</u>:

Surface area to volume ratio decreases.

<u>Explanation</u>:

When the cell enlarges beyond its capacity, it fails to supply enough material that can cross the membrane sooner so as to occupy the cellular volume. Hence the diffusion rate also decreases so as the ratio. The cell carry out its various functions to sustain through diffusion when diffusion rate is low it will ultimately affect the ratio. Bigger size affects the diffusion of the material to the out of the cell. as we know the diffusion occurs across the surface of the cell.
