Write a summary of what you have learned in "Introducing the Microscope". Be sure to include steps on how to focus, how to solve for magnification, and what a field of view is and how to measure it.
"Introducing the Microscope" is a text that shows what a miscroscope is, how it works, its composition and its functions. This is a very important text for those who have no experience with this equipment, but can use it at any time.
One of the most important points in the text is about the operation and correct use of the microscope. Where concepts are explained, promoting the proper functioning of the equipment.
According to the text, we must have a full conviction of the microscope's field of view, which is the vision we have when we position our eyes under the microscope to visualize tiny and invisible elements with the naked eye.
However, the field of view needs to be focused and this is done with the manipulation of the microscope that will allow the vision to have a very well developed and detailed quality.
In addition, a microscope has many lenses, which can increase and decrease the size of the image. This promotes the enlargement of the image and makes the image can be seen more closely and in more detail.

Define embryonic stem cells. Explain the pros and cons of Embryonic Stem Cells
Answer:
Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.
Explanation:
Adult Stem Cells
Embryonic Stem Cells
Induced Pluripotent Stem Cells
Pros
Trans differentiate and and reprogramming of these cells is possible but is not well studied
Thought to be less likely to be rejected if used in transplants
Success has already been demonstrated in various clinical applications
Can maintain and grow for 1 year or more in culture
Established protocols for maintenance in culture
ESCs are pluripotent cells that can generate most cell types
By studying ESCs, more can be learned about the process of development
Abundant somatic cells of donor can be used
Issues of histocompatibility with donor/recipient transplants can be avoided
Very useful for drug development and developmental studies
Information learned from the “reprogramming” process may be transferable for in vivo therapies to reprogram damaged or diseased cells/tissues
Cons
Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.
Cannot be grown for long periods of time in culture
Usually a very small number in each tissue making them difficult to find and purify
Currently there is no technology available to generate large quantities of stem cells in culture
Process to generate ESC lines is inefficient
Unsure whether they would be rejected if used in transplants.
Therapies using ESC avenues are largely new and much more research and testing is needed
If used directly from the ESC undifferentiated culture prep for tissue transplants, they can cause tumors (teratomas) or cancer development
Methods for ensured reproducibility and maintenance, as differentiated tissues are not certain.
Viruses are currently used to introduce embryonic genes and has been shown to cause cancers in mouse studies

Explanation:
It takes 83 mL of a 0.45 M NaOH solution to neutralize 235 mL of an HCI solution. What is the concentration of an HCI solution?
Answer:
168ml
Explanation:
It takes 83 mL of a 0.45 M NaOH solution to neutralize 235 mL of an HCI solution, than the concentration of HCl will be 0.158 mL.
What is concentration?The amount of a chemical substance in a mixture is expressed by the substance's concentration.
What is neutralize?
The interaction of H+ ions with OH- ions produces water in a neutralization reaction, which occurs whenever an acid as well as a base reacts to form water and salt.
Calculation of concentration.
Given data:
[tex]V_{1}[/tex] = 83 mL
[tex]C_{1}[/tex]= 0.45 M
[tex]V_{2}[/tex] = 235 mL
[tex]C_{2}[/tex] = ?
Concentration of HCl solution will be calculated by using the solution.
[tex]C_{1} V_{1} = C_{2} V_{2}[/tex]
where, C is concentration and V is volume.
Put the value of given data in above equation.
[tex]C_{2} =C_{1} V_{1} / V_{2}[/tex]
[tex]C_{2}[/tex] = (0.45 M)(83 mL) / 235 mL
[tex]C_{2}[/tex] = 0.158 mL.
Therefore, the concentration of HCl will be 0.158 mL.

If you measured an entire bar of soap and compared it to the piece of soap from this activity, would the bar and the piece have the same mass, volume, and density?
Answer:
Different mass
Different volume
Same density
Explanation:
Intensive physical properties are those properties of a substance that is not dependent on amount i.e. do not change in response to changes in the amount of the substance. Intensive properties include density, temperature, boiling point etc.
On the other hand, extensive properties are those properties that are dependent on the amount of the substance. For example, mass and volume are extensive properties.
Hence, according to this question, measuring an entire bar of soap and comparing it to a piece of soap, the bar and the piece would have a:
- Different mass ( size dependent)
- Different volume (size dependent)
- Same density (size independent)
A student is making a model to illustrate the functions of ADP and ATP in photosynthesis. Which model best illustrates the role of ATP in photosynthesis?
a power plant that generates energy
a hammer that helps break apart water molecules
a pan that carries coal
a rechargeable battery that stores and releases energy
Answer:
a rechargeable battery that stores and releases energy
Explanation:
Adenosine triphosphate (ATP) is a chemical molecule that has the ability to store and release energy for metabolic activities to occur in living cells. ATP stores energy in its phosphate bonds when an ADP molecule is phosphorylated while it releases the energy when the phosphate bond is broken.
According to this question, a student is making a model to illustrate the functions of ADP and ATP in photosynthesis. The model that " ATP is a rechargeable battery that stores and releases energy" best illustrates the role of ATP in photosynthesis. This is because an ATP molecule just like a rechargeable battery can be charged with energy to store and discharged to release the energy.

Which of the following molecule is NOT needed for the Calvin Cycle to take place?
a. H2O
b. CO2
c. RuBP
d. NADPH
(5C enzyme)
Answer:
C.
Explanation:
The chemical RuBP, is not even mentioned in that cycle, making it the least viable answer.
H2O is not needed for Calvin cycle to take place.
Option A is the correct answer.
Calvin cycle is the cycle that take place during photosynthesis and it is light depend where Co2 enters the pores of the stomata of the leaf.
It is in three stages.
1. Carbon fixation: Co2 react with with three molecules of the five carbon acceptor molecule (RuBP) to produce ,three molecules of carbon compounds that divide to form three carbon compound (3-PGA) in the presence of rubisco enzyme.
2. Reduction stage: In this stage,6 ATP and 6 NADPH convert six 3-PGA molecules to 6 molecules of three-carbon sugar (G3P). It is a reduction reaction because NADPH lose electrons to a three-carbon intermediate to produce G3P.
3. Regeneration : G3P molecule move to produce glucose, five G3Ps are recycled to produce the RuBP acceptor. This reaction requires ATP.
Therefore, H2O is not included in Calvin cycle.
