What are the energy sources for the calvin cycle?

The energy sources for the Calvin cycle are ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis. These molecules provide the necessary energy and reducing power for the conversion of carbon dioxide into carbohydrates in the Calvin cycle.

Explain what might happen if the third step of the Calvin cycle did not occur.?

I assume you have the Holt, Rinehart and Winston worksheets.

So your question was :

'If the RuBP consumed in Step 1 was not regenerated in Step 4 of the Calvin Cycle, then,

a. CO2 would stop diffusing into the stroma.

b. the cycle would speed up because of an increase in CO2 molecules.

c. the plant cell would lack G3P molecules.

d. the plant cell would stop bonding carbon atoms from CO2 into organic compounds

The two you can immediately cross out are A and B because diffusion of CO2 has nothing to do with RuBP. As for B, the cycle would not speed up. If anything, it would slow down or stop.

Now, we are left with:

c. the plant cell would lack G3P molecules.

d. the plant cell would stop bonding carbon atoms from CO2 into organic compounds

The article you read on the front sheet [I will not copy that down] never specified much on whether or not the cell would stop bonding carbon atoms from CO2 into organic compounds, so I personally settled for C. My reasoning behind this is that G3P is made from RuBP, and without it, the cell, like the answer states would lack G3P.

TL;DR the answer is 'D'

I do hope this helped. Good luck with Bio!

Edit: answer is D

How does temperature and precipitation affect biodiversity in different biomes?

Temperature influences, and in many cases determines, the characteristics of each biome. Temperature causes certain plants to grow and certain animals to thrive, and these plants and animals define the biomes and create the ecosystem.

What effects do modern farming techniques have on the world biodiversity?

  1. Growth hormones used on animals get into our food sources and may be affecting humans.
  2. Monoculture crops can be easily wiped out by new diseases.
  3. The use of chemical fertilizers pollutes the environment.

How does marine biodiversity differ from land biodiversity?

Marine biodiversity refers to the variety of species and ecosystems found in the ocean, while land biodiversity refers to the variety of species and ecosystems found on land. Marine biodiversity is influenced by factors such as salinity, temperature, and pressure, while land biodiversity is influenced by factors such as temperature, altitude, and soil type. Marine biodiversity is often higher than land biodiversity due to the vast and connected nature of ocean ecosystems.

How does size of land mass relate to species diversity?

The population sizes of a species is directly coordinated with the size of the island. A large island close to shore would have a low extinction rate and a successful immigration rate from animals coming over from the mainland.

What are 4 activities that can threaten the biodiversity?

habitat loss-when a rainforest is made into cattle pasture, a meadow made into a small parking lot, a swamp draining for house etc.

habitat fragmentation-a road cuts across wildeness areas, and as building projects expand into new areas, many habitats are becoming virtual islands.

biotic issues- some organisms that need large areas to gather food. large predators cannot obtain enough food if they are restricted to a small area.

Abiotic issues- another problem with habitat fragmentation is that it can change the climate of the area. a tropical rain forest is canopy and moist, now suppose loggers came in and cut everything down, except for a plot of land. the once moist and shady area is now exposed to sunlight and winds and the area dries out.

Why is high biodiversity better?

because there are different weather conditions

How does modern fishing threaten biodiversity?

overfishing, and fishes getting traped in abandoned nets

What are the characteristics of Alpine Forest?

Dont really know. but if you want to know facts on the desert type in the google bar

what is a desert like?

and go to the first webstite you see :) GOOD LUCK CHUCK

oh and go to google and type in SCARY MAZE GAME!! OMG its so creepy do the maze hehehe

What are some negative effects on biotechnology?

Some negative effects of biotechnology include ethical concerns related to genetic engineering, potential harm to the environment through the release of genetically modified organisms, and the potential for increased economic disparities as access to biotechnologies may be limited to certain groups.

What are the Pros and cons of wildlife conservation?

Pro: more animals to hunt. Con: the amount of land that must be allocated solely to maintaining these animals can be prohibitively expensive.

The conservation of wildlife is very important to maintain a proper biodiversity. Future generations want to enjoy these animals as well as we do.

What is direct value of biodiversity in biology?

Nature is a Possibilitist, exploring every niche, every possibility, both for animate and inanimate entities and particles.

There is a concept taught in business colleges called "opportunity cost" -- you can try addressing your question from that angle.

The simple answer is: the more possibilities for survival the more species have, the more probable is the survival of any individual, because more is more than less.

It is difficult to value one's progeny, let alone the delight of seeing and feeling a small creature or plant or crystal or entity of nature one has newly discovered! The value of discovery is joy, i.e. happiness, and some people are happy with $90 while others need $90 million. Well, would it be enough to own 40 stars and all their planets? When is enough enough?

Imagine two planets, one with life, another without. Which would you choose to explore? How much would you pay to be the one selected to explore the plaent with life on it?

Imagine two planets, one incapable of producing life, and one perhaps capable of producing it. Which would you value more? By how much?

But your question is ego-centric in that it is bio-centric. Inanimate objects have rights too. Where would you be without the minerals for your body, or the raw water or energy, or sunlight or air? These "lifeless" things are required for life, so you must account for them as well.

Which then brings us to valuing the Periodic Table of Elements and atomic and subatomic particles. How much is a single neutron worth, if you could not read and understand this sentence without it?

One thing is for sure: the cost of everything inflates every year -- people want more money for what they value and resources are limited, until new means of survival are found. It is the INVENTORS OF ADAPTATION WHOM WE MUST VALUE MOST HIGHLY THEREFORE.

And who are they?

They are the species we share the planet with, whom we have co-evolved with for countless milennia. We should grant them property rights.

But, in a way, protons and neutrons and electrons have property rights without Humanity's getting involved ... to a point. It is only when things acquire an aesthetic or a use or a "goodness" of some kind that they are "valued."

And who values things? Accountants do. Accountants record economic activity and set the stage for bookkeepers and families to do so. Largely, their basis for so doing involves the expiration and utility of assets being converted to revenue streams via the Cost of Goods Sold being marked up to Sales Revenue price levels. And that is for what the market will bear, generally speaking.

So the answer to your question is: whatever the highest bidder will pay for it.

Currently, I am the highest bidder. You laugh, but I am. I have a secret way of revaluing things according to how they are PERCEIVED that only I understand among all the humans alive on the planet. You must be laughing by now but I assure you this is no joke. For I am the creator of DELUSIONS, the impossible, which soon becomes †he UNLIKELY, then THE CONCEIVABLE, then THE FEASIBLE, per the perceptions of the very brightest. I have my delusions due to being schizophrenic; they are random neural net firings and they have "no" known source. The Universe knows where they come from, no one else does. You can look up "random neuron firings" after googling schizophrenia and follow what I'm talking about. The same applies to people of creativity and imagination. They can "not" account for the source of their ideas for the most part. That is because they fail to grasp the word "not" very well. I am the great UNTHIS. I do not believe in "not." So I just BELIEVE. I am a logical positivist, a Possibilitist. And I am a very unique one at that; I belong to †he creator gene pool for them. My name means "Yahweh." No other family can say that in the way that I can and have it be true. I am speaking less from ego and more from direct experience, exactly so IN FACT.

People disLIKE crazy people because they are unLIKE them. They have yet to research the word "like" etymologically, until it means the same thing as "look" and "lick" -- that is, until their words are mere output from their sensory input and brain's thruput processing. But Outputs/Inputs = Efficiency and Efficiency is supposedly always less than 1. Actually, nothing disappears. Mass and Energy are conserved. We are learning to recycle the Outputs formerly called "Waste."

If you want to learn the true value of biodiversity, go to work for Waste Management, Inc. and go as far as you can in Math and Chemistry and Physics. Learn to recycle EVERYTHING, especially ideas. Read Euclid's "Elements" as the highly dramatic story of cultural evolution it truly is! Read the Bible as a series of Spirit Lessons, rather than as history. Research the etymology of the words.

Do you know that the first logical occurrence of the word "OR" in the Bible, according to Strong's Concordance, is when one man said to another, "You take these fields to graze your sheep and I will take the far fields OR I will take these and you may have the far lands." You can also research when IF and AND and PLUS and MULTIPLY were first used, as translated. As you may know, the AND() and OR() functions are tremendously important in Computer Science. But that is a metaquestion beyond "bio"diversity. People are still arguing over the rights to that same land. People are limited in their imaginations and they fail to realize what their words MEAN anymore, and how their words actually turn into ACTIONS. It's largely a question of "Honor."

Enough, OK? Your values you bring to an object well-crafted of quality and merit are yours to decide what labor you will trade for them, and materialism has to do with Matter, which is 3% of the known Universe. Have fun!

Why are higher levels of biodiversity good for ecosystem stability?

The higher the biodiversity, the higher the number of species, and the lower the rate of extinction. A decrease in biodiversity means a single species will become extinct and this will have a negative impact on other organisms for all organisms in an ecosystem are connected.

Were humans meant to be gay?

The simple answer is: We don't know yet.

Back in 2005 Swedish scientists found that gay men's brains were more similar to a female brain then a male one. There have not yet been a gay gene found but research is still going on in many countries.

Recent evidence shows that homosexuality is caused by a mixture of both genetic sequences (not a single gene) and prenatal hormonal factors.

What is need to preserve biodiversity?

Biodiversity means the number of different kinds of animals that exist in the world. Nature preserves protect and nurture a variety of animals, some of which would otherwise become extinct.

Which biome would contain the most biodiversity in decidious tree species?

I could be wrong, but I am pretty sure it is not the temperate deciduous forest, but the rain forest biome that has the most biodiversity.

Which could most likely have a lasting negative impact on the biodiversity of an area?

Construction of buildings,soil theft,all forms of pollution,loss of water reservoires,Carelessness of the public(educated people) is major cause for everything.

Why does biodiversity lead to a more stable ecosystem?

Decreases in biodiversity result in a loss of genetic variation. This affects the ecosystem in varying levels of severity. For example, if you lose a pack of wolves in the forest, in that group you lose a genetic line that can hunt well by scent, then the prey species of those wolves (such as rabbits) may increase, they will eat more vegetation, and drive out less successful herbivores from the forest.

Why is Philippines considered mega biodiversity country?

Managing Diversity What is Diversity? Diversity is the multitude individual differences and similarities that exist among people. Individual differ in the following ways: * Ethinic origin, physique, gender * Early family experiences, social and cultural factors, sexual orientation, national culture * Motivaion, attitudes, personality traits, inteeligence, abilities, and perceptions. What is managing diversity? Managing diversity implies valuing these individual differences in an organisation. It means relating to and working with, people who hold different perspectives; who bring different qualities to the work place and who have different aspirations, customs and traditions. Differences challnge our views, perceptions and attitudes and require an altered frame of reference to assess a situation or event. Valuing and managing diversity require organisation to recognise the unique contribution that every employee can make. ( Mannual of Institute of Administrative Management 2005) Suleman Hadi

What is the terrain in a deciduous forest like?

i think it is rocky or flat depending on where you are.

How do you respect diversity?

Respecting diversity involves acknowledging and valuing the unique backgrounds, perspectives, and experiences of individuals from different cultures, genders, races, and abilities. It means actively listening to others, promoting inclusivity, and fostering an environment where everyone feels safe and empowered to express themselves. Additionally, it requires challenging biases and stereotypes while advocating for equity and understanding within communities and organizations. Embracing diversity enriches our collective experiences and leads to more innovative solutions.
