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.

5. an animal that has both male and female reproductive organs Hermaphrodite

6. an animal without a backbone invertebrate

7. free-floating aquatic animals with a structure similar to a jellyfish medusae

8. the transformation of a larva to an adult; occurs only in animals having great differences in form between the larva and adult metamorphosis

Explanation:

Body cavity is a fluid-filled space inside a multicellular organism  with the protective role. The coelom is the main body cavity, found in allmost all animals. Those that don't have coelom are called acoelomata. An example are Platyhelminthes.

Symmetry refers to the proportion of an animal: its reflection, rotation or scaling. The body symmetry of animals might be radial, bilateral, spherical or asymmetric.

Two major group of animals are Vertebrate and Invertebrate, with or without with backbone.

Hermaphrodite organisms are those that contain both, male and female reproductive organs, characteristic for invertebrates.

*<br> 1. In the water cycle, water goes from a liquid to a gas during which stage?
Ira Lisetskai [31]

Answer:Evaporation Evaporation is simply the process by which liquid turns into a gas. Water (a liquid) turns into vapor (a gas) when heat energy is applied to raise its temperature to 100°C (212°F). Water in the liquid state is a compound, and the heat breaks up the bonds into water molecules, which is gaseous.
