Answer:

"A liver cell synthesizes glycogen from glucose." ---> build large molecules.

"A plant cell synthesizes cellulose from glucose." ---> structural support.

"A brain cell uses the energy in glucose to synthesize ATP" obtaining energy or reserve energy.

Explanation:

Carbohydrates are classified into large groups, where the simplest are monosaccharides (ex: glucose), followed by desacarids, trisaccharides and polysaccharides as the most complex.

Carbohydrates are hydrated carbonic structures that also attract water masses, they are very useful when it comes to generating energy reserves, energy sources, structures of tissue or vegetable support, and together with proteins are one of the most fundamental components of extracellular matrices to nourish various cells, such as proteonglycans or glycoproteins.

Elizabeth is conducting an investigation to study how molecules are transported into and out of a cell. Elizabeth builds a model
k0ka [10]

The given question is incomplete, the complete question is:

Elizabeth is conducting an investigation to study how molecules are transported into and out of a cell. Elizabeth builds a model of a cell using a U-shaped tube. A barrier, which is permeable to water, but not sugar, is placed on the bottom of the tube to model the cell membrane. Elizabeth adds two different solutions to each side of the tube. The solute in each solution is sugar and the solvent is water. The initial levels of solution in Side A and Side B are equal. The concentration of sugar in Side A is lower than the concentration of sugar in Side B.

What is Elizabeth likely to observe?

A. Water molecules will move from Side A to Side B. The solution level on Side A will fall and the solution level on Side B will rise.

B. Water molecules will move from Side B to Side A. The solution level on Side A will rise and the solution level on Side B will fall.

C. Sugar molecules will move from Side A to Side B. The solution level on Side A will fall and the solution level on Side B will rise.

D. Sugar molecules will move from Side B to Side A. The solution level on Side A will rise and the solution level on Side B will fall.

Answer:

The correct answer is statement B, that is, the molecules of water will move from side A to side B. The level of solution on the side A will fall and the level of solution on the side will elevate.

Explanation:

Based on the given information, it is clear that the barrier is only permeable to water, thus, movement of water will take place through osmosis down the gradient, that is, from lower to the region of higher solute concentration. The water seems to equalize the concentrations of solute present on side A with the concentrations of solute present on side B.

Osmosis refers to a phenomenon in which the molecules of solvent seem to pass via a semipermeable membrane from the area of less concentration to the area of higher concentration, therefore, equating the concentrations on both sides of the membrane.

1. Discuss why you think the unit exercise only had you create two bones for the model’s hand rather than five? 2. How would rig
netineya [11]

Answer:

1. Discuss why you think the unit exercise only caused you to create two bones for the model's hand instead of five.

R = why the prosthesis can be adapted according to the needs of each of the users.

2. How would the rigging (and animation) be more difficult if it did not include guide bones, pole targets, and other rigging elements that are not directly part of the mesh "skeleton"?

R = the bones of the fingers that are still present help us create the measurements of the missing fingers since in this way we create a more harmonic and sesthetic hand, and when these fingers are not present it is more difficult to create in the animation since it can be noticed a little deformed since the requests cannot be correct and the fingers can be seen in very different sizes from one to the other.

3. Describe the ways your model originally looked "off" in warp / skinning or in the animation / keyframe process

A = I would not know how to answer that because I do not have any key program to carry out the prosthesis but I can guide you a little bit about a prosthesis program which you can see in an animation program

The digital model of the affected hand was obtained using modeling techniques in Blender, Rhinoceros and Mesh to model conversion software in Solid Edge. As a result, a 3D digital model of the affected hand was obtained on which the mechanisms of the prosthesis to be implemented can be worked on and adjusted.

After developing the model of the prosthesis volume, measurements were taken and adjusted to the plaster model that was previously obtained. Figure 13 shows how the prosthesis model was fitted to the plaster hand model. Subsequently, with the measurements obtained from this model, the prosthesis mechanisms are designed for the three missing digits in the user's hand.

4. Imagine that you are creating a robot instead of a human character. What design changes could you make to the model in terms of rigging and skinning to make the character more "robotic"?

R = the physical aspect, and that the movements are more rigid and not so fluid to give the robotic touch, since currently robots move very fluidly and can make faster expressions and make it look more metallic and not treat it to do with such a humanoid aspect.

5. How would you face the challenge of animating a "boned" model, such as a traditional RPG slime monster, or alternatively a snake or detailed tail animation?

R = you have to make an animation character that looks gelatinous, as through the program you have to create a mass that looks translucent so that it can simulate that the character does not have bones, because if you make it a solid object we would be losing the effect that the character is gelatinous that is supported without bones.
