After a few hours, the cells of each sponge would re-aggregate and form three new sponges.

We can reach this answer because:

In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

Answer:

Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

atoms

An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

What are the 8 states of matter?

Bose–Einstein condensate.

Fermionic condensate.

Degenerate matter.

Quantum Hall.

Rydberg matter.

Rydberg polaron.

Strange matter.

Superfluid

Answer:

1. Liquid, Solid, Gas

2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.

3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.

4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.

B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point

5. Ionic charges are stronger.

Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.

Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.

Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

Answer: reading paper books and magazines,  sleeping in beds under cotton sheets, having a sandwich for lunch , sitting at wooden desks , I picking wildflowers , eating a favorite breakfast cereal.

Explanation: These are all correct because each has to deal with plants. For example, reading the paper books, sleeping in the bed and sitting at the wooden desk all have to due with the products that come from plants. Paper, cotton, and wood are all grown from plants and turned into resources. Next picking flowers, eating foods are also direct examples of how plants help us. Picking flowers that come directly from plants. Then eating food that is grown from plants shows that it is directly plants providing for humans.

The scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

Cell division may be defined as the process by which a parent cell divides into two or more daughter cells.

The stretching of a cell to allow for more fat storage is usually done by the process of cell growth, but not by the process of cell division.

Therefore, the scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have  a negative effect on aquatic species. The negative effects include:

Toxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.

The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female  aquatic species such as reef fish.

Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Explanation:

ATP synthase is a protein that catalyses the conversion of adenosine diphosphate (ADP) and inorganic phosphate to the energy storage molecule adenosine triphosphate (ATP) (Pi). It's classed as a ligase since it modifies ADP by forming a P-O bond (phosphodiester bond).

Cells store energy in the form of ATP. These storage molecules are made in the mitochondria, which are small organelles present in eukaryotic cells and are commonly referred to as the cell's "powerhouse."

The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.

Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.

The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.

Answer:

I would think Channel proteins but I could be wrong

The sodium potassium pump is the only one of the options that requires the transfer of the terminal phosphate group of ATP.

Active transport is the process of moving molecules across a cell membrane against their concentration gradient. This requires energy, which is provided by ATP hydrolysis.

Aquaporins are water channels that allow water to move through the cell membrane without requiring energy. Carrier proteins and channel proteins are also involved in passive transport, which does not require energy.

The sodium potassium pump is an example of active transport. It uses the energy from ATP hydrolysis to move sodium ions out of the cell and potassium ions into the cell. This creates an electrochemical gradient, which drives the movement of other ions and molecules across the cell membrane.

The sodium potassium pump is essential for maintaining the electrical potential of the cell membrane. It is also involved in the transport of nutrients and waste products into and out of the cell.

Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.

Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.

Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.

The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.

So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.
