This category is for questions about biodiversity, or species diversity, which is composed of genetic, species, and ecosystem diversity.

What is the Calvin Cycle and who discovered it?

The Calvin cycle is the reaction that happens in plants during photosynthesis and carbon filtration without light. Melvin Calvin and two associates used the radio-active carbon 14 to trace the pattern of the carbon atoms during filtration.

Do monkeys have a excretory system?

Yes, monkeys have an excretory system which includes organs such as the kidneys, ureters, bladder, and urethra. These organs work together to remove waste and excess substances from the body through urine.

What are two things the students should look at before evaluating which container is better for the environment?

They should examine things like:

Can it be recycled?

How much CO2 is produced to make or dispose of?

How long do these things take to decompose?

Is it biodegradable?

Does the container leech toxic materials into the water or soil?

Students who are using Ask.com to search for answers in their APEX coursework should note that they need to paraphrase their answers so their teachers (who are not stupid) do not give them back revisions for plagiarism ;).

What biom has the greatest diversity?

Probably the ocean biome, but the rain forest biome on land would have the highest species diversity.

What type of area will undergo the fastest ecological succession?

Areas that have been severely disturbed, such as after a volcanic eruption or a wildfire, tend to undergo ecological succession at a faster rate. These areas have little to no vegetation and soil, allowing pioneer species to establish themselves quickly and kickstart the succession process.

What happens during the carbon fixation step of the Calvin cycle?

Products such as G3P or PGAL are produced in the Calvin cycle in C3, C4, and CAM plants. Carbon fixation helps each plant adapt to the particular environment they live in. C4 plants are those such as sugarcane or grasses. CAM plants are the cactus plants or plants that live in the desert. It also helps with the production of ATP.

What human activities are huge threats to biodiversity?

Some of the major human activities threatening biodiversity include deforestation, habitat destruction, pollution, overfishing, and invasive species introduction. These activities can disrupt ecosystems, leading to the decline or loss of plant and animal species. Protecting biodiversity requires addressing these threats through conservation and sustainable resource management.

Is diversity permanent or transitory?

Diversity can be both permanent and transitory. It depends on the context and factors influencing the diversity. In certain cases, diversity can be a constant state due to external factors. However, in other situations, diversity may fluctuate over time based on changes within a system or society.

What is organisation embracing diversity?

An organization embracing diversity is one that values and respects individual differences among its employees or members, including but not limited to race, ethnicity, gender, age, and physical abilities. It actively promotes inclusivity, equity, and a sense of belonging for all individuals, leading to a more innovative and productive work environment.

Which of the following threats to biodiversity isn't directly due to humans?

One example of a threat to biodiversity that isn't directly due to humans is natural disasters such as volcanic eruptions or earthquakes. These events can cause significant ecological disturbances and impact biodiversity by altering habitats and causing species loss.

What systems has the highest level of species richness and endemic species?

Tropical rainforests have the highest level of species richness and endemic species. These ecosystems support a wide variety of plants and animals due to their warm climate, ample rainfall, and diverse range of habitats. Many species found in tropical rainforests are endemic, meaning they are found nowhere else in the world.

What is one reason there is more species diversity in the tropics?

there is more solar energy available in the tropics than in the temperate zones.

What is the foci of an eclipse?

The foci of an eclipse refer to the two points within the elliptical orbit of the Moon where the Earth is located at the time of the eclipse. These points define where the alignment between the Sun, Earth, and Moon occurs, leading to either a solar or lunar eclipse.

What is the morphological characteristics of an organism?

Morphological characteristics refer to the physical features of an organism such as size, shape, color, and structure. These characteristics are observable traits that help to distinguish different species from one another and play a crucial role in taxonomy and classification.

Do neutral mutations affect biodiversity?

Neutral mutations do not have a significant impact on biodiversity because they do not affect an organism's ability to survive and reproduce. Biodiversity is mainly influenced by mutations that provide a fitness advantage or disadvantage, leading to changes in the frequency of different traits within a population. Neutral mutations simply accumulate over time without impacting biodiversity directly.

Why would a golf course have less biodiversity than a natural ecosystem how might the lower biodiversity affect surrounding ecosystem?

A golf course is mainly grass which is probably not native to that area. When a golf course is made, may species of plants, trees, shrubs, ponds ect. are removed because they are not needed. This reduces the amount of habitat for species in that area. So the biodiversity is reduced by removing the varying vegetation, and removing animals/insects and other organisms that once lived in that area. This causes stress for these animals/plant species to find a new niche to live in. So they migrate to surrounding ecosystems in which they might not be native to. This can cause competition with other organisms (reducing population numbers for certain species) or even extirpation of a species from that area if it cannot adapt.

I am just throwing out ideas, hope it helped. I'm sure there is much more to this topic.

What factors contribute to genetic diversity?

Factors that contribute to genetic diversity include mutations, genetic recombination during sexual reproduction, gene flow between populations, and natural selection. These processes introduce new genetic variations into populations, increasing the overall diversity of the gene pool.

Which molecule represents the end product of the Calvin cycle?

The end product of the Calvin cycle is glyceraldehyde-3-phosphate (G3P), which is a three-carbon sugar molecule. It can then be used to synthesize glucose and other carbohydrates for plant growth and energy storage.

How do alligators interact with other living things?

Yes. I suggest you research on the web about these animals. Try the Crocodile Hunter website and search for a way to contact the website. They do answer peoples' questions. You may even be able to watch some old videos with Steve Irwin talking about the ways that crocodilians court each other by blowing bubbles in the water. Alligators communicate in a variety of way, all of which are shown in body posture. An angry alligator will arch its back, hiss and display its teeth with a wide open mouth. If it is placid (sunning itself for instance) it will sit still with its mout proped open.

What is surface-level diversity?

Surface-level diversity refers to the observable characteristics of individuals, such as age, gender, race, and ethnicity. These attributes are typically easy to identify and do not reflect a person's values, beliefs, or experiences. Companies often focus on promoting diversity at this level as a first step toward building a more inclusive workforce.

Why is it important to have a high level of biodiversity?

High biodiversity is important because it increases ecosystem stability, enhances ecosystem services such as pollination and pest control, and it supports resilience to environmental changes. It also provides genetic diversity that can help species adapt to new challenges and plays a crucial role in providing food, medicine, and other resources for humans.

What helps weaken the bonds so that energy can be released and then later help reform them?

Chemical reactions weaken bonds to release energy, such as breaking bonds in reactant molecules to form products. Later, these bonds can reform through reverse reactions or other processes like condensation. Energy is used and released in these transformations.

Why are most biodiversity hotspots located in the tropics?

There is consistent sunlight which allows for producers to grow continually, versus the higher latitudes where there is variation in the amount of sunlight between seasons, i.e. winter and summer.
