Answer:

The level of specialization is given by the function.

The function of the organ makes the cell as it becomes mature, its more specific function becomes.

First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.

After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.

Explanation:

The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.

Answer:

Sponges use choanocytes or flagellated channels to get nutrients from the feeding cells to other parts of their body.

Explanation:

Sponges are marine animals with a sac-shaped body. The epidermis is composed of polygonal flat cells called pinacocytes and pores protected by porocytes. Under the epidermis, there is a protein matrix called mesenchyme, which is composed of spicules and amibocytes. By the interior side of the sponge, there are the choanocytes. These are ovoid cells that can be shaping the spongocoele (internal cavity of the sponge), with an extreme attached to the mesenchyme and the other extreme projected to the spongocoele, or can be grouped in spaces called flagellated channels.

These animals depend on water to get oxygen and food to the inside of the sac and take excrements and reproductive cells to the outside. Sponges feed on small detritus particles and suspending organisms that get near the animal by water streams produced by choanocytes.

Particle size is essential. Only the small ones can get through the flagellated channels, where they get stuck to the choanocytes and are encapsulated by the cells. If the choanocytes are too small, the particle is transferred to the amibocytes for digestion. These last ones also act as food storages. Excrement products are dragged by a water stream.

What is the smallest or most specific level of organization organization you and your neighbors all have in common

bixtya [17]

Answer:

The cell

Explanation:

The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is the cell.

This is in accordance with the cell theory which has three basic components, including:

1. The cell is the basic unit of life

2. All living organisms are made up cells

3. Cells arose from pre-exsiting cells.

Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.

UkoKoshka [18]

The correct answer should be loss.
When your skin is cut open, obviously a little blood will run out as a result of that. This case is no different - the person who fell and has an abrasion on the knee will experience a slight loss of blood through that tiny wound which is the result of them falling on the ground.
