Explanation:

In general, tumors occur when cells divide and grow excessively in the body. Normally, the body controls cell growth and division. New cells are created to replace older ones or to perform new functions.

What would happen to a sample of your red blood cells if they were placed in a hypotonic solution?
timofeeve [1]

<em>Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm) </em>

<u>Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up. </u>

<em>The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC. </em>

As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.

The plentiful nature of resources in the tropical rainforest reduces competition for them.
Lina20 [59]
That statement is false

The plants still have to undergo a fierce competition in order to obtain sunlight. The taller trees will obtain more sunlight while overshadowing the smaller one.

Meanwhile , even though there are a lot of food resources in the rain forest, it also have many animals that compete for the same food.

Ostrovityanka [42]

Answer:

Viruses and prions are considered microbes.

Some microbes are visible to the naked eye.

Explanation:

Microbes are the tiny organisms that can not be seen with unaided eyes. However, this does not hold true for all and some microbes like <em>Epulopiscium fishelsoni</em> can be seen with unaided eyes. Bacteria, viruses, protozoans, and prions are some of the microbes. Viruses are the microbes that have a protein coat around their genetic material. Prions are proteins that can cause infections. Prions do not have any genetic material.

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.

The map shows the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa.
lukranit [14]

In the two maps that show the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The color coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.

Hence the answer is A)When an area is malaria free, the HbS allele frequency is between 0 and 2.02.
