1,421 Questions
How can we improve biodiversity?
*Having more animals reproduction
*Reduce the pollution that affect the biodiversity
*Support local and regional projects aimed at tackling biodiversity losse biodiversity.
*Plant local flowers, fruits and vegetables. ... *Take shorter showers!...
*Invasive alien species. *Overexploitation of the natural environment..
Why does biodiversity vary in ecosystems?
The ecosystem is sensitive to environmental changes. These environmental changes whether chemical or physical directly affect the species richness and composition, the biodiversity of the area.
What does a exponental growth curve look like?
An exponential growth curve typically appears as a J-shaped or steeply rising curve on a graph. Initially, the growth is slow, but as time progresses, the rate of increase accelerates sharply, creating a steep upward trajectory. This pattern reflects a situation where the growth rate is proportional to the current value, resulting in rapid and continuous expansion. In biological contexts, this could represent populations or resources growing without constraints.
What factor is largely responsible for the loss of biodiversity seen in the world today?
as it will lead to some major problems such as global warming , pollution of natural resources etc.
How conservation related to biodiversity?
Management of human use of the biosphere so much to provide maximum benefits for sustainable genrations current while maintaining their potential to meet the needs and aspirations of future generations: Thus conservation in the positive, which includes preservation, maintenance, sustainable use, restoration and enhance the natural environment.
Conservation is the protection, preservation, management or restoration of wildlife and natural resources like forests and water. Maintaining the survival of species biodiversity and habitats of many that are threatened by human activities can not be ensured.
Biodiversity can have many interpretations and is most commonly used to replace the term more clearly defined and established long, species diversity and species richness.
What are the general characteristics of protista?
protozoa are microscopic and unicellular organisms. The protoplasm is differentiated into an outer ectplasm and inner endoplasm. A protozoan has one or more than one nucleus. Locomotory organs are pseudopodia , cilia or flagella. Reproduction takes place by sexual or asexual method.
How humans have an positive effect on biodiversity?
They are important because if they were no invertebrates the humans wouldnt be able to do stuff like fishing cause they need worms.Also because things like flower pollination we need bees to pollinate the flowers.If they were no bees the flowers the animal pollinated flowers race would stop. So point being made that we need invertebrates because they carry out important duties to humans
Who first coined the term hot spots with reference to biodiversity?
Raymond F. Dasmann in the 1968 lay book A Different Kind of Country
Does selective breeding increase or decrease biodiversity?
Similar, but not identical. And as most species are extinct beyond repair (we´ll probably never extract good dinosaur DNA) even backcrossing with living species is impossible.
Because what would we do without beauty. Life would be dual and bland without the beauty of the universe. I believe beauty inspires us, and without it who is to say that something as beautiful as art would exist. Without the beauty of the universe inspiration is lost. In a beautiful place amazing things can happen. Can you imagine a world without trees, flowers, waterfalls, and butterflies? I can't.
How can habitat alteration affect biodiversity?
Habitat alteration is a change that occurs particularly in the environment where organisms live and is considered as a threat to the survival of every known species. Alteration in habitat is usually caused by urbanization, overfishing, agriculture and coastal development.
What types of human activity decrease species diversity?
When people destroy the home's of animals and we build house's and other biuldings which then animals have no homes and will die.
What is a low biodiversity mean?
Bio (life) diversity (different unique individuals) low (quantity of). Low quantity of different life forms.
Why is biodiversity important and how can we preserve it?
Biodiversity is the variety of life on Earth. Biodiversity include the genetic variety among individuals in a species, the number of species in an ecosystem and the variety of ecosystems in the biosphere. The main factors causing the threat to biodiversity are pollution, habitat destruction, introduced species and overexploitation.
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
Were does the Calvin cycle take place in?
The Calvin cycle takes place in the stroma of chloroplasts.
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?
- Growth hormones used on animals get into our food sources and may be affecting humans.
- Monoculture crops can be easily wiped out by new diseases.
- 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.
