Answer:

spherical shape

Explanation:

Left: passive bloodstains. Right: bloody shoe print transfer pattern. Because blood demonstrates surface tension, or cohesive forces that act like an outer skin, a drop of blood dropped at a 90° angle forms a near-‐perfect spherical shape.

The main site of secretion of all substances, except for one, is the proximal convoluted tubule. What is the one substance that
kogti [31]

Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.

<h3>Renal reabsorption and secretion</h3>

Renal reabsorption is defined as the movement of water and specific solutes from the renal tubule back into the plasma.

Renal secretion is defined as the process by which waste ions and hydrogen ions pass from the renal capillaries into the renal tubule to be excreted into the urine.

At the proximal convoluted tubule, calcium is reabsorbed but not secreted. Therefore, Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.

I need help with offspring science
REY [17]
The alleles of offspring vary, some are dominant and some are recessive, meaning that some traits get passed down and some don't, for example,: a dominant trait might be blue eyes, a parent would have blue eyes, and pass that dominant trait to their child so that the child would also have blue eyes, recessive traits are traits that skip a generation.
For example a grandparent might have black hair, but their child won't have black hair, however, their grandchild will have black hair, therefore the black hair trait is recessive and skipped a generation
Hope this helps
