Answer:

Cell membranes are usually more fluid than flexible. Fluid means that the embedded proteins or carbohydrates attached to the cell membrane have the ability to move around within the membrane

Answer: "The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container."

A spectacular marine animal has a network of glassy spicules that forms a sac-like structure. This animal does not have true tis

PolarNik [594]

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 affect do algae blooms have on ocean ecosystems?(1 point) increased underwater plant population decreased carbon dioxide in

Umnica [9.8K]

An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels, to more harmful effects like blocking sunlight from reaching other organisms, causing a depletion of oxygen levels in the water, and, depending on the organism, secreting toxins into the water.

If the net force an object at rest is zero the object will remain at rest. True or false

FromTheMoon [43]

True

Explanation:

If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.

Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "

If no net force acts on a body, it will forever remain at rest.
The force on a body causes its motion and acceleration.
A body will continue in uniform motion if no external force acts on it.
