explain why the suspension of isolated chloroplasts became alkaline when illuminated?​

Answers

Answer:

Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase.  More important is that illumination is required for carbon fixation.  As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in.  In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.

Explanation:

Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.

Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.

When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.

As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.

Therefore, the formation of carbonic acid from the CO2 will raise the pH.

7. CASE STUDY For Biosphere 2 to meet its goal, why was it necessary for it to replicate a
variety of climates?

Answers

Answer:

For Biosphere 2 to meet its goal, it was necessary to replicate a variety of climates. The original goal was to provide a successful model for human space colonies, and with this goal in mind, scientists and engineers built prototypes of several environments that can replicate the real-life climates (in order to see how the complex processes work). This provides a viable ecological system in outer space. In the model, there are different climates used to see how different factors of the Earth affect each other.

Explanation:

Suppose insects that feed on the plants were placed inside the growth chamber as well. Predict how this might affect the levels of CO2 in the growth chamber. How does this model, on a smaller scale, represent the cycling of carbon through Earth's systems?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.

This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?

Answers

Answer:b

Explanation:

The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N  the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

How net force will be calculated?

The net force acting on the bicycle is:-

F net = Total force acting on bicycle

In above question,

Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)

So,

Fnet = F1 + F2

Fnet = 150 N -84 N

Fnet = 66 N

Now the acceleration will be

Fnet = mass X acceleration

In above question,

Fnet = 66 N

Mass = 100 Kg

So,

Acceleration = Fnet/Mass

Acceleration = 66/100

Acceleration = 0.66 m/sec^2

Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N  the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

Adenine, thymine, cytosine and guanine are ___________________ instructions to cells.

Answers

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.

How does transcription proceed?

Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.

A random mutation occurs and the GGA codon is changed to CGA. What effect does this
substitution have on the amino acid being called for? Explain your answer.

Answers

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Due to Base Substitutions Mutations.

What happens when a mutation changes a codon?

A nonsense mutation refers to a base substitution in which the changed nucleotide transforms the codon into a stop codon.

Such a modification leads to a premature termination of translation, which can badly affect the formation of proteins.

Thus, Base Substitutions Mutations take place.
