CALVIN CYCLE:
The Calvin cycle is also known as light independent reactions or dark reaction of photosynthesis. It is the second stage of the photosynthetic process where glucose is synthesized. The Calvin cycle makes use of the products of the light dependent reaction namely: ATP and NADPH.ATP and NADPH are used to synthesize glucose molecule. In the process of Calvin cycle, carbon dioxide (CO2) is fixed and not oxygen. Therefore, the true statement about the Calvin cycle is: Both ATP and NADPH are needed to make sugars.Learn more at: https://brainly.com/question/3199721?referrer=searchResults
Which characteristics do all Protista have in common?
A. They are all autotrophic and mobile.
B. They are all heterotrophic and produce spores.
C. They are all parasites and reproduce s3xually or as3xually.
D. They all lack cell specialization and prefer moist environments.
Answers
None of the given options accurately describes characteristics that all Protista share in common. The Protista kingdom is characterized by its diversity and encompasses a wide range of organisms with varying characteristics, including modes of nutrition, mobility, reproduction, and habitat preferences.
Among the given options, none of them accurately describes characteristics that all Protista share in common. The Protista kingdom is a diverse group of eukaryotic organisms that do not form a natural taxonomic group. However, there are some general characteristics that are commonly observed within this kingdom.
Option A: They are all autotrophic and mobile. This is incorrect because Protista include both autotrophic (e.g., algae) and heterotrophic (e.g., protozoa) organisms. Additionally, not all Protista are mobile.
Option B: They are all heterotrophic and produce spores. This is incorrect because, as mentioned earlier, Protista include both autotrophic and heterotrophic organisms. Additionally, not all Protista produce spores.
Option C: They are all parasites and reproduce sexually or asexually. This is incorrect because not all Protista are parasites, and their modes of reproduction can vary widely.
Option D: They all lack cell specialization and prefer moist environments. This is incorrect because some Protista do exhibit cell specialization, and while many prefer moist environments, there are also Protista that inhabit diverse habitats such as marine, freshwater, and even terrestrial environments.
In conclusion, none of the given options accurately describes characteristics that all Protista share in common. The Protista kingdom is characterized by its diversity and encompasses a wide range of organisms with varying characteristics, including modes of nutrition, mobility, reproduction, and habitat preferences.

Why is crop rotation beneficial for maintaining an appropriate nutrient supply
Answers
Answer:
Some plants absorb all the nutrients in the soil, like the cotton plant, and some return them to the soil, like peanuts. The latter plants are called nitrogen-fixing plants. Rotating these and the former plants (like cotton), replenishes the nutrients in the soil and creates a healthy agricultural cycle.

Answer:
A.) Vacuoles
Explanation:
A.) is correct because vacuoles are responsible for the storing nutrients, water, and waste.
B.) is incorrect because chromosomes are made primarily of condensed DNA. They exist to make DNA separation during nuclear division more efficient.
C.) is incorrect because the mitochondria is where cellular respiration takes place. This process is necessary for energy production.
D.) is incorrect because cell membranes do not store things. Rather, the cell membrane protects the inside of the cell, allows for the existence of a fixed environment inside of the cell, and facilitates the movement of molecules that wish to enter or leave the cell.
Examine the layers of rock. Identify and explain which layer contains the oldest fossils.
Answers
Answer: D
Explanation:
The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be seen.
give brainliest i dont have it yet
In river valleys, cliffs, hillsides, and man-made exposures like quarries and road cuttings, sedimentary rocks of the appropriate age are exposed, Thus, option D is correct.
What is sedimentary rock?The bottom has the oldest layers, while the top has the newest layers. Sedimentary rock frequently contains a significant amount of fossils because sediments may contain once-living animals.
It is possible to see the shape or form of a once-living organism in a fossil, which is an organism that has been preserved in rock. The type of rock in which fossils are most likely to form is sedimentary rock.
The rock strata are named according to the historical period during which they were formed, and they are arranged from oldest at the bottom to youngest at the top.
Therefore, bottom layer contains the oldest fossils.

What patterns in the data are relevant to deciding whether the species are the same or different, but do not support your claims? Why are these sources of data in general important to scientists in determining common ancestry?
Answers
Gene sequences provide one of the most compelling arguments for shared descent. Comparative sequence analysis looks at how the DNA sequences of several species relate to one another.
Is there a pattern to evolution?The patterns that evolution might take over time can vary. Predation pressures and environmental factors can influence how animals exposed to them evolve in different ways. illustrates the three primary types of evolution: parallel, convergent, and divergent.
What patterns may be utilised to determine shared ancestry?By contrasting the macroscopic appearance of diagrams or photographs, it is possible to deduce general patterns of relatedness among embryos of various animals. It is possible to find patterns of resemblance in the embryological development of many species using visual data.

Answers
Answer:
decreasing the distance between Hox and Bloxdecreasing the mass of Hox and Bloxdecreasing the mass of BloxExplanation:
Decreasing the distance between Hox and Blox will make it easier to increase the pull of gravity between the two planets, because less gravity would be needed to increase the pull of gravity. Hope that made sense. Decreasing the mass of Hox and Blox will decrease the amount of gravity needed to make the pull of gravity stronger. Because decreasing the mass of hox and blox is one of the correct answers ( of course i can't be 100% sure because the grader may be looking for different answers than normal), I am assuming that decreasing the mass of Blox is an answer too. Hope this made sense and helped.
