The inner layer of a sponge, the mesohyl, contains several types of amoeboid cells, which secrete materials to form a skeleton-like structure for support.
the exterior of a sponge is comprised of flattened cells that form an outer epithelium.
Choanocytes are flagellated cells that line internal cavities and are responsible for pumping water and small particles into the sponge. 
Sponges are truly multicellular organisms.
Sponge cells are unique because throughout their development they can differentiate from one type of cell to another

Answer: sponges are

phylum Porifera

Explanation: There are about nine thousand species of sponges. Sponges have three types of cells which includes

1) Pinacocytes: They are thin walled and flat cells. They line the outer surface of a sponge. Pinacocytes are slightly contractile. The contraction may change the structure of some sponges. Most pinacocytes forms tube like contractile porocytes. Porocytes are responsible for water regulation.

2) Mesohyl: It is a jelly like layer present underneath the pinacocytes. Amoeboid cells are present in mesophyl. The Amoeboid cells are called mesenchyma cells. These cells are responsible for reproduction, secretion, skeletal elements, transporting and storing food and forming contractile rings around openings in the sponge wall.

3)Choanocytes: Also called collar cells are present below the mesohyl. They form the lining of the inner chamber. Choanocytes are flagellated cells. They have a collar like ring of microvilli surrounding a flagellum.The flagellum creates water currents through the sponge.

Why are G protein only found in Eukaryote cell ?
Levart [38]

Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

Alma brought her 6-month-old son to the doctor for a well-baby visit. The doctor says that her son's weight is in the 20th perce
sveta [45]

This means that her son is small compared to other 6 month old children.

A percentile is a measure between 0 and 100 that compares children of similar age in order to know if a particular child is growing well. The higher the percentile number, the bigger the child is compared to other children of same age. If a child is in the 50th percentile for height, it means the child is in the middle of the pack.

humans enjoy eating largemouth bass what would happen if the fishing industry fished every largemouth bass out of the ecosystem
Kruka [31]

Then they would go extinct

we would not be able to eat them anymore

and the food chain will get messed up because some animals eat the large mouth bass and now they cant, and also the animals that the large mouth bass eats will overpopulate because the large mouth bass isn't there to eat them

How can the arrangement of furniture in a room influence an individual’s behavior?
Ira Lisetskai [31]
An individual's behavior can be influenced sociologically, psychologically and physiologically by the arrangement of an interior environment. Dependent on functionality, co-working space etc of the room, a person may require more or less privacy which is related directly to productivity, social balance, personal happiness and other problematic or positive behavioral encounters.
