How does the hatch slack pathway compare with the Calvin cycle?

C3 carbon fixation or the Calvin cycle is a metabolic pathway for carbon fixation in photosynthesis. This process converts co2 and ribulose bisphosphate into 3-phosphoglycerate through the following reaction:

6 CO2 + 6 RuBP → 12 3-phosphoglycerate

In C4 , carbon dioxide is drawn out of malate and into this reaction rather than directly from the air.

Since every CO2 molecule has to be fixed twice, the C4 pathway is more energy-consuming than the C3 pathway. The C3 pathway requires 18 ATP for the synthesis of one molecule of glucose while the C4 pathway requires 30 ATP. But since otherwise tropical plants lose more than half of photosynthetic carbon in photorespiration, the C4 pathway is an adaptive mechanism for minimizing the loss.

How do you maintain a biodiversity?

Don't cut trees or use hairspray, cut down on driving and don't waste electric because if you do then they'll have to make more so try and recycle

edit:

While all of this is true, none of these directly maintain biodiversity. Also, hairspray propellants are are no longer CFCs, and are more or less harmless to the environment. Some ways to maintain biodiversity:

1. Stop planting monoculture crops in replacement of diverse forests/plains

2. Stop the use of herbicides

3. Carefully use fertilizers (to prevent algal blooms etc)

What process is responsible for the diversity of plants within a species?

Genetic variation within a species resulting from sexual reproduction, mutation, and genetic recombination is responsible for the diversity of plants. This allows for adaptation to different environments and ensures the survival of the species in changing conditions.

How do you recognize biological diversity?

Biological diversity can be recognized by the variety of species, genetic diversity within species, and the diversity of ecosystems and habitats. It includes the differences in physical characteristics, behaviors, and adaptations that enable organisms to survive in different environments. Studying the distribution and abundance of species in an area can also help in recognizing biological diversity.

A community that has great species richness contains?

A wide variety of different species that coexist in the same ecosystem, contributing to a diverse and interconnected web of life. This can lead to increased stability and resilience within the community, as different species play unique roles and provide various services that support the overall health of the ecosystem.

How does a human fit into a pond ecosystem?

A human can impact a pond ecosystem by introducing pollutants from runoff or waste, altering the habitat through construction or removal of vegetation, and affecting water quality through activities like fishing or boating. Conversely, humans can also help protect pond ecosystems by promoting conservation efforts, reducing pollution, and restoring habitats to enhance biodiversity.

Describe three ways to preserving biodiversity can come into conflict with human interests?

One way preserving biodiversity can come into conflict with human interests is because people need lumber to build homes and furniture. Other things are keeping livestock to eat and the growing population.

Does both light reactions and the Calvin cycle produce three-carbon sugars?

No, the light reactions produce high-energy molecules (ATP and NADPH) while the Calvin cycle, which is part of the light-independent reactions, uses these molecules to produce three-carbon sugars through carbon fixation.

Where do the reactant come from for Calvin cycle?

glucose and oxygen are the reactants in this equation, glucose come from the sugars broken down from your food and oxygen come from your lungs, passing through the thin cell wall of the bronchioles into your bloodstream which are in turn absorbed by the mitochondria and the process of respiration takes place

What type of cultivation has decrease biodiversity?

Monoculture cultivation, where only one type of crop is grown over a large area, can decrease biodiversity by reducing the variety of plant and animal species that can thrive in the area. This lack of diversity can lead to imbalances in ecosystems and increase vulnerability to pests and diseases.

What is a adaptation for a vanilla plant?

An adaptation for a vanilla plant is its climbing behavior, using aerial roots to cling onto trees for support and maximizing sunlight exposure in the forest canopy. This allows the vanilla plant to access necessary resources and thrive in its natural habitat.

How does adaptations affect the diversity of a species?

Adaptations make the species different from other species, and if they are passed down, they will make more species with these differences.

Why is poaching a threat to biodiversity?

The detrimental effect depends what you're poaching, but it's never good. Hunting is an effective means for managing game animals and poaching is the act of taking game animals outside of dedicated seasons or killing a non-game animal that isn't considered a pest. Pests can be killed by anyone any time and often by just about any method. Hunting seasons are arranged to protect the mating and gestation periods of game animals. Bag limits are put in place to protect the overall population of game animals. When people poach, aside from being a criminal act, it's a disservice to the species they are poaching and if the animal is endangered, it contributes toward extinction.

How many NADPH are produced in the Calvin Benson cycle in photosynthesis?

For each two water molecules, the noncyclic electron flow will produce 1 O2 molecule, 2 NADPH, and 1 ATP.

What is the major benefit of ureterosigmoidoscopy?

Ureterosigmoidoscopy allows for direct visualization and inspection of the lower urinary tract using a flexible endoscope, providing detailed information on the anatomy and potential abnormalities. This procedure can help diagnose conditions affecting the ureters, bladder, and urethra, such as stones, tumors, or inflammatory changes, leading to more targeted treatment.

What are all the different types of selection in biology?

There's artificial selection and natural selection.

Artifical selection is when humans breed organisms for the traits they want, while natural selection is when individuals with the best fitness survive and produce more offspring than other individuals.

Three types of natural selection are directional, stabilizing, and disruptive.

  1. Directional selection is when, between two traits, one trait becomes more common in a population because it benefits survival and/or reproduction more than the other trait.

    For example, some bacteria have weak antibiotic resistance while others are stronger. In an environment full of antibiotic drugs, antibiotic-resistance would eventually increase in a bacteria population.

  2. Stabilizing selection is when, between two traits, the trait that's somewhere in between becomes the most common while the other two separate traits become less common.

    For example, gall-flies produce different-sized galls. Woodpeckers eat large galls, and wasps often attack small galls, middle-sized galls, which aren't targeted by predators, become more common.

  3. Disruptive selection is when, between two traits, the trait in between them becomes less favorable, while the two separate traits become more favorable.

    For example, lazuli buntings range between brown color and blue color. Both colors help attract mates, but the bluish-brown birds are targeted by adults, so the bluish-brown become less common as the pure brown birds and the pure blue birds become more common.

There's also sexual selection, where a trait that increases mating success becomes more common in a population over generations.

Why does genetic variation increase the chance that some organisms in a population will survive?

In any given population, individuals have different strengths and weaknesses. You many have noticed that some people are less affected by cold or heat than others. Black people in the north can suffer from Rickets. White people in the south can suffer from skin cancer. Some people get sick less often than others. Some people get by on less food than others. Some people run faster than others. At times one of those abilities might be the most important for survival. Our ancestors who ran the fastest would do the best at catching wild animals. Being strong would help kill them. On the other hand, a person with excellent motor skills could make the best tools. The gazelle that survives does not have to be the fastest but the slowest will not outrun the cheetah. The fastest gazelle might run too fast and overheat and get exhausted. He will collapse and a lion will get him. Some people never seem to get sick. They have a good immune system. Still a new pathogen could decimate the population and wipe out such people. Their immune system could not deal with a type of pathogen never met before. If AIDS becomes more contagious, then the world will be repopulated by the people living in that part of Russia near Finland. They can not catch AIDS. A variety of natural and developed abilities helps.

What is the importance of habitat diversity?

Habitat diversity is important as it supports a wide variety of species, promoting biodiversity and ecological resilience. Different habitats provide unique resources and environmental conditions that allow for the survival and reproduction of diverse organisms. A diverse range of habitats also helps to maintain ecosystem functions and services essential for human well-being.

What is the name of a person who threaten people?

A person who threatens others can be referred to as a bully or harasser.

How does traditional ecological knowledge affect biodiversity?

Traditional ecological knowledge, passed down through generations, plays a critical role in the conservation and management of biodiversity. Indigenous and local communities often have intimate understanding of their local ecosystems, which helps in sustainable resource management, species conservation, and maintaining ecological balance. By incorporating traditional ecological knowledge into modern conservation practices, we can enhance biodiversity conservation efforts and promote harmonious coexistence between humans and nature.

How would you respond to someone who makes a statement that it is not important to protect areas of temperate and polar biomes because most of the worlds biodiversity is in the tropics?

Firstly, all areas are important. While the tropics have the most biodiversity, there are different types of organisms in each biome and all contribute to global biodiversity. They each promote ecosystem sustainability and balance nature

What are three types of genotypes that exist for pea plant height?

Three types of genotypes that exist for pea plant height are:

  1. TT - Homozygous dominant genotype for tall height
  2. Tt - Heterozygous genotype for tall height
  3. tt - Homozygous recessive genotype for short height

What are 4 reasons why biodiversity is important?
