Why is Pluto no longer considered a planet? It is not large enough to be a planet. Pluto does not orbit the sun as originally th

ought. It does not orbit in an area clear of other celestial bodies. It is too far away from the sun to be part of our solar system.

Pluto is not considered a planet due to all the reasons you stated above

elena55 [62]3 years ago

Answer:

it would be A. It is not large enough

Explanation:

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

Taking carbon from the carbon dioxide in the air (called an inorganic molecule) and attaching the carbon to an organic molecule
natita [175]

Answer:

Carbon fixation and Rubisco enzyme

Explanation:

The carbon fixation is usually referred to as the process that involves the transformation of CO₂ into organic molecules. This process occurs during the time of photosynthesis, where, the CO₂ is obtained from the atmosphere by the leaves of plants in the presence of sunlight and converts it into useful organic molecules. This is also known as the Calvin cycle, in which all the consumers are dependent on.

Rubisco is usually defined as an enzyme that is secreted by the plants and it is essential to carry out the initial step for the carbon fixation process. It is commonly written as 'RuBisCO'.

Select the three correct answers.
loris [4]

Answer:

a, b, c are correct

Explanation:

Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.

Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.

Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.

There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.

Therefore, the correct options are (a), (b), and (c).

which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know
ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.
