Answer:

pore

Explanation:

Sponges are simple multicellular organisms. They do have aggregate cellular level of body organization. All major body functions in the sponge such as exchange of gases, circulation, and excretion are carried out by diffusion between the cells located at the pore (opening) of the sponge and the water which passes through the pore.   All the cell present within the sponge take oxygen from water through diffusion. Similarly, carbon dioxide is released into water diffusion. The excretory product produced as a by-product as a result of the breakdown of protein is diffused out by individual cells into the water as it passes through the sponge.

Contractile vacuoles are organelles that are responsible for excretion function. They perform osmoregulation which manages wastes, water and other needed materials in the cell. They are found in some prokaryoric organisms like the algae, protists, amoeba and other unicellular organisms.

What is the most likely mechanism by which testosterone functions inside a cell?
Fed [463]
<span>Testosterone achieves his effect by binding to his androgen receptor (nuclear). Because testosterone is steroid hormone (derived from cholesterol), it has a possibility to free diffuse through the cell membrane. When testosterone binds, the receptor undergoes a structural change which allows it to move into the cell nucleus and dimerize. Receptor dimer than binds directly to the specific sequence of the DNA called hormone response element (HRE) which results in regulation of gene expression.</span>
