14.The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.  To emphasize this point even more, the equation for photosynthesis is the opposite of cellular respiration.

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.

The pathways of the carbon cycle cellular respiration and all exergonic processes produced in the cell, through which substances oxidize and chemical energy is released.

All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen.

There are therefore two types of breathing and they are aerobic respiration and anaerobic respiration. The latter also called fermentation. Aerobic respiration  (oxidative phosphorylation)

Therefore, The pathways of the carbon cycle cellular respiration and all exergonic processes produced in the cell, through which substances oxidize and chemical energy is released.

Answer:Explanation: taxonomy was invented with kingdoms, phylum, orders, families, genus, and species before evolution was proposed. Classical taxonomy is based on observable characteristics of organism, not on Darwinian evolution. Cladistics the most modern form of taxonomy is based on Darwinian evolution.

"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.

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.

The amount of a chemical substance in a mixture is expressed by the substance's concentration.

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.

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.

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)

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
