explain the sugar translocation in the plant starting with the leaf cell
(source cell) to the root cell (sink cell).

Answers

Answer 1

Answer: I think this is it.. Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements.

step by step process of photosynthesis

Answers

Answer:

Step 1-Light Dependent. CO2 and H2O enter the leaf.

Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- Light Dependent. The electrons move down to enzymes.

Step 4-Light Dependent. Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent. The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

C. The chloroplasts use oxygen, water, and sunlight to produce

D. The mitochondria use carbon dioxide, water, and sunlight to

Answers

Answer:

B

Explanation:

the equation for photosynthesis is:

carbon dioxide + water ---> glucose +oxygen

                                     (light)

The statement that correctly describes the process of photosynthesis is that chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen. The correct option is B.

What is photosynthesis?

Photosynthesis is the process of producing food, nutrition, and energy. It is done by plants and algae because only they contain chlorophyll. Those organisms containing chlorophyll can perform photosynthesis.

It is a chemical process and the process involves, carbon dioxide, water, and sunlight, and it produces sugar and oxygen as a byproduct. The oxygen is released, whereas the sugar gives the energy.

The process can be described as chloroplast absorbing the sunlight for plants, and the process can only occur in the presence of light or sunlight.

Thus, the correct option is B. The chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen.

A student is observing an image of an object that could be a comet, meteoroid or asteroid. Which of the following questions
would BEST confirm that the object is a comet?

A. Does the object contain ice?

B. Does the object contain metals?

C. Where is the object found?

D. How big is the object?

Answers

Answer:

A does the object contain ice

Explanation:

The BEST question that would confirm that the object is a comet is "Does the object contain ice?" Hence the correct option is A.

What are comets?

Comets are small, icy celestial bodies that originate from the Kuiper Belt and the Oort Cloud. As they approach the Sun, they heat up and release gas and dust in the form of a coma and a tail, which can be observed from Earth. Therefore, if the object contains ice, it is most likely a comet.

Meteoroids, on the other hand, are smaller rocks that travel through space, and asteroids are larger rocks that orbit the Sun between Mars and Jupiter. Neither meteoroids nor asteroids typically contain ice.

As for the other options, whether the object contains metals or how big it is does not provide enough information to determine whether it is a comet, asteroid, or meteoroid. And while the location of the object may provide some clues about its origin, it is not a definitive factor in determining whether it is a comet.

Explain the function of enzymes and how enzymes
can be denatured.

Answers

Answer:

They speed up chemical reactions and are denatured by high temperatures and high pH.

Explanation:

Enzymes speed up chemical reactions. They have specifc conditions that allow them to work effectively. Temperature and pH affects how enzymes work. The optimum temperature is the temperature at which enzymes will function best. In most instances they are around 37-40°C (in the human body). Temperatures above this will denatured (destroy) the enzymes therefore they cannot do their task. At Temperatures below the optimum temperature the enzymes activity is decreased to the point where they may not be active.

Optimum pH is the pH at which the enzymes works best. These vary based on the type of enzyme. Any pH above the optimum will denatured the enzymes (destroy). pH below the optimum will decrease the ezymes activity to the point where they may not be active

If you and a friend hold a book a pencil, a paper clip and a crayon at the same height in the air, and drop them all, which item will hit the ground with the greatest force?

Answers

well to this answer it will be the heaviest object that will fall the faster the crayon will fall much much faster than the other objects listed.

The items will all hit the ground at the same time as they have an equal force.

It should be noted that the law of conservation of energy applies in this case. In such a situation, the weight or mass of the object is inconsiderate.

In this case, since a book a pencil, a paper clip, and a crayon at the same height in the air, are dropped, they will hit the ground with the same force.

Therefore, they'll fall at the same time.

What is fracking fluids?

In order to enhance the amount of hydrocarbons that may be extracted, drilling operations use fracking fluid (also known as frac fluid). The fluid stops the well from corroding. Among other things, it prevents blockages, bacteria from growing, and lubricates the extraction process.

In summary, the chemical composition varies from well to well and is complicated. Depending on the exposure amount, several of these substances can be dangerous to human health.

According to estimates from the oil and gas sector, chemical additives only make up about 1%.

4. In transcription, how come the whole DNA molecule is not copied into mRNA?

Answers

Answer:

Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.

Explanation:

DNA is transcribed into mRNA and this mRNA has the complementary sequence of DNA but is not identical to DNA.

What is transcription?

The mechanism for transferring genetic information becomes more complicated if both strands of DNA serve as transcriptional templates.

If both strands of DNA serve as transcriptional templates, dsRNA would be produced, preventing the synthesis of proteins.

Because its sequence is complementary to the DNA template, the mRNA is not an exact replica of the DNA segment even though it includes the same information.

Therefore due to complementary not identical sequences of mRNA during transcription whole DNA molecule is not copied to mRNA.
