Describe five types of threats to biodiversity?
There are several types of threats to biodiversity. The following list contains five of these threats. Pollution, this can harm all living things. Climate change, animals that are native to certain climates, do not do well when the climate changes. Destruction to habitats, large fires, or floods can ruin the habitat of many creatures. Sickness, disease can wipe out large numbers of living things. Finally, humans are also a threat. When humans take over land or move out to what was one wild areas, it is harmful.
What are the three values of biodiversity?
The three values of biodiversity are ecological value (maintaining ecosystem function and stability), economic value (providing resources for industries such as agriculture and pharmaceuticals), and intrinsic value (acknowledging the inherent worth of all species).
How does biodiversity help humans?
Biodiversity provides essential ecosystem services such as clean air and water, pollination of crops, and natural pest control, which directly benefit human health and well-being. It also supports the development of new medicines and technologies, contributes to food security, and promotes overall resilience to environmental changes and disasters. Furthermore, diverse ecosystems offer recreational and aesthetic value, enriching human experiences and quality of life.
What are four ways that human activity can reduce biodiversity?
Human activity can reduce biodiversity by altering habitats, hunting species to extinction, introducing toxic compounds into food webs, and introducing foreign species to new environments
Some examples are:
1) Deforestation
2) Fires
3) Farming
4) Poachers
What are the reactants and products in the Calvin cycle?
Reactants: ATP, NADPH2, CO2,
Products: Glucose, Oxygen
What is the Calvin cycle responsible for?
The Calvin cycle is responsible for converting carbon dioxide from the atmosphere into glucose through a series of biochemical reactions in the stroma of chloroplasts. This process is essential for plants to produce sugars and other organic compounds needed for growth and energy production.
What does the blastopore become?
At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes
What is pretense to diversity?
Pretense to diversity refers to a situation where an individual or organization claims to value diversity and inclusion but their actions do not align with those values. This could involve superficial efforts, tokenism, or not actively promoting diversity in practice. It is important to ensure that efforts towards diversity are genuine and impactful.
What is the process in which communities evolve to have greater biomass and species richness?
Communities evolve to have greater biomass and species richness through ecological succession, which is the process of change in the species structure of an ecological community over time. As more species establish themselves and interactions between species become more complex, the community can support a greater biomass and biodiversity. This process can be influenced by factors such as disturbance events, climate change, and species interactions.
In eukaryotes where does the Calvin cycle occur?
The Calvin cycle, a series of chemical reactions that occur in the stroma of chloroplasts, takes place in eukaryotic organisms, including plants and algae. This process is important for carbon fixation and the synthesis of carbohydrates using carbon dioxide, ATP, and NADPH generated during the light-dependent reactions of photosynthesis.
Genetic diversity refers to the variety of genes within a species or population, which carries the hereditary information that determines an organism's traits. This diversity plays a crucial role in evolution, adaptation, and the overall health of a population.
What is the definition of growth yield?
Growth yield is a measure that represents the amount of growth or biomass produced by an organism per unit of substrate consumed or energy harvested. It is often used in microbiology and biotechnology to assess the efficiency of microbial growth.
How do plants adapt to the gulf coast?
Plants in the Gulf Coast region have adapted to the high humidity, sandy soils, and frequent hurricanes by developing deep root systems, water-storing tissues, and flexible branches to withstand extreme weather conditions. Many native plants have also evolved to thrive in the salty coastal environments by excreting excess salt through specialized glands or storing it in their leaves.
Difference between regression coefficient and correlation coefficient?
difference between correlation and regression?
(1) The correlation answers the STRENGTH of linear association between paired variables, say X and Y. On the other hand, the regression tells us the FORM of linear association that best predicts Y from the values of X.
(2a) Correlation is calculated whenever:
* both X and Y is measured in each subject and quantify how much they are linearly associated.
* in particular the Pearson's product moment correlation coefficient is used when the assumption of both X and Y are sampled from normally-distributed populations are satisfied
* or the Spearman's moment order correlation coefficient is used if the assumption of normality is not satisfied.
* correlation is not used when the variables are manipulated, for example, in experiments.
(2b) Linear regression is used whenever:
* at least one of the independent variables (Xi's) is to predict the dependent variable Y. Note: Some of the Xi's are dummy variables, i.e. Xi = 0 or 1, which are used to code some nominal variables.
* if one manipulates the X variable, e.g. in an experiment.
(3) Linear regression are not symmetric in terms of X and Y. That is interchanging X and Y will give a different regression model (i.e. X in terms of Y) against the original Y in terms of X.
On the other hand, if you interchange variables X and Y in the calculation of correlation coefficient you will get the same value of this correlation coefficient.
(4) The "best" linear regression model is obtained by selecting the variables (X's) with at least strong correlation to Y, i.e. >= 0.80 or <= -0.80
(5) The same underlying distribution is assumed for all variables in linear regression. Thus, linear regression will underestimate the correlation of the independent and dependent when they (X's and Y) come from different underlying distributions.
How would the earth change if there were no plants or animals?
You can kill part of the earth, including humans. Because humans eat some types of animals, and if we don't have the animals to eat, all humans can die. The animals will die too, they are just like humans.
A category of living things that is defined by how they gain energy is called?
A category of living things that is defined by how they gain energy is called a trophic level. This concept helps to describe the flow of energy through an ecosystem, with each level representing a different feeding position in a food chain.
Why ripple pond makes leaf bob up and down but the leaf hardly moves from side to side?
The ripple pond makes the leaf bob up and down because the waves create a vertical motion that lifts and lowers the leaf. However, the leaf hardly moves from side to side because the force of the waves is primarily pushing the leaf up and down instead of displacing it horizontally.
What is the difference between morphology and growth arrangement?
Morphology refers to the study of the form and structure of organisms, including their external appearance and internal organization. Growth arrangement, on the other hand, refers to the specific patterns in which organisms grow and develop over time, including the ways in which cells divide and arrange themselves in the organism's structure. Essentially, morphology focuses on the physical characteristics of an organism, while growth arrangement looks at the processes involved in its development.
Name the person who found out photosynthesis?
Photosynthesis is the process by which plants use sunlight (light energy) to drive a chemical reaction that eventually results in a carbohydrate and some oxygen. Let's look at the term "photosynthesis." The first section, "photo," is the English form of a Greek word meaning light, "phos." "Synthesis" is the creation or generation of a product; in this case, a carbohydrate and oxygen. So, the word photosynthesis means "using light to make something."
What is terrestrial pollution?
Terrestrial pollution refers to contamination of land or soil by various pollutants such as chemicals, heavy metals, plastics, and waste materials. Sources include industrial activities, agriculture, urbanization, and improper waste disposal. Terrestrial pollution can have detrimental effects on soil quality, vegetation, wildlife, and human health.
Give the Significance of the egg cell micropyte funiculus and synergid?
The egg cell is the female gamete that fuses with the sperm cell during fertilization to form a zygote. The micropyle is a pore in the egg cell membrane through which the sperm enters during fertilization. The funiculus is the stalk that connects the egg cell to the ovary wall. The synergid cells are involved in guiding the pollen tube to the egg cell during fertilization. Collectively, these structures play essential roles in the reproductive process of plants.
its no surprise to me because when you leave a potato in a little room for a while you Will start to see a small shot, this small shoot is like a stem, so when it is about 1cm long you can plant it.
The whole biological process will become disrupted, breaking the food chain. As the pond bottom fills, the fish have less room for their territory, so they go to take another fishies territory. it becomes a huge battle for survival. And after all that is done.....there is nothing but pond, and some micro-organisms.
How does the concentration of salt water affect the crispness of potato chips?
Increasing the concentration of salt in the water will create a hypertonic solution. When potato slices are soaked in this hypertonic solution, water will move out of the potato cells through osmosis, resulting in a crispier texture due to the removal of excess moisture.
What Is Biodiversity A Measure of?
I am studying BIODIVERSITY in school, Biodiversity is lots of things to do with nature and stuff. It can mean from the circle of life, food chain, how things biodegrade
and more check it up on WIKIPEDIA or in a Dictionary to find out more.
