What is biodiversity
Answer:
the variety of life in the world or in a particular habitat or ecosystem
Answer:
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level.
Explanation:
Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richer in the tropics. These tropical forest ecosystems cover less than ten percent of earth's surface, and contain about ninety percent of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life.
Rapid environmental changes typically cause mass extinctions. More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species, are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as four trillion tons of carbon. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.
The age of the Earth is about 4.54 billion years. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland. More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth .. then it could be common in the universe."
Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multicellular phyla first appeared.[34] The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life. The Permian–Triassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the Cretaceous–Paleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the non-avian dinosaurs.
The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity. Named the Holocene extinction, the reduction is caused primarily by human impacts, particularly habitat destruction. Conversely, biodiversity positively impacts human health in a number of ways, although a few negative effects are studied.
The United Nations designated 2011–2020 as the United Nations Decade on Biodiversity. and 2021–2030 as the United Nations Decade on Ecosystem Restoration, According to a 2019 Global Assessment Report on Biodiversity and Ecosystem Services by IPBES 25% of plant and animal species are threatened with extinction as the result of human activity. An October 2020 IPBES report found the same human actions which drive biodiversity loss have also resulted in an increase in pandemics.
In 2020, the fifth edition of the UN's Global Biodiversity Outlook report, which served as a “final report card” for the Aichi Biodiversity Targets, a series of 20 objectives set out in 2010, at the beginning of the UN's Decade on Biodiversity, most of which were supposed to be reached by the end of the year 2020, stated that none of the targets – which concern the safeguarding of ecosystems, and the promotion of sustainability – have been fully met.

What is done in the Benedict test?
Answer:get there weatth
Explanation: because u haev to add a comma
Below the Food samples label, drag tube A into the Food sample holder. The Benedict test is a chemical test used to detect the presence of reducing sugars in a solution. Here's the Benedict test is performed.
A food sample, which is suspected to contain reducing sugars, is dissolved in water and heated to create a solution is called preparation of sample. A small amount of Benedict's reagent, which is a blue alkaline solution containing copper sulfate, is added to the sample solution is called Mixing with Benedict's Reagent. The mixture is then heated in a water bath or directly on a flame. Heating is important because the blue copper ions in the Benedict's reagent are reduced to form brick-red precipitate of copper(I) oxide. Depending on the concentration of reducing sugars in the sample, the color of the mixture changes. If there are no reducing sugars, the solution remains blue.
In the context of your instructions, "Below the Benedict test, click the Test button" likely refers to a digital or virtual environment where you're simulating a laboratory procedure. By clicking the "Test" button, you would be initiating the process described above, and the system would likely simulate the color change based on the presence and concentration of reducing sugars in the virtual sample.

Hormones are proteins that?
A) Coordinate different body systems
B)Cause catabolic reactions
C) Aid in digestion of food
Answer:
I'm not sure that it's the write answer still..
Explanation:
B)Cause catabolic reactions
Hormones are proteins that Coordinate different body systems. Option A is correct.
Hormones are chemical messengers that are produced by glands in the body. They are released into the bloodstream and travel to target cells, where they bind to receptors and initiate a specific response. Hormones play a role in many different body functions, including growth, development, metabolism, reproduction, and stress response.
Some examples of hormones include:
Insulin: Insulin is a hormone that helps to regulate blood sugar levels.Thyroid hormone: Thyroid hormone helps to regulate metabolism.Growth hormone: Growth hormone helps to promote growth and development.Oxytocin: Oxytocin is a hormone that helps to induce labor and breastfeeding.Hormones are essential for maintaining homeostasis, or the state of balance in the body. When hormone levels are too high or too low, it can lead to a variety of health problems.

Explanation:
[tex]{ \sf{ \boxed{ { \sf{ \boxed{ \sf \red{Answer}}}}}}}[/tex]
Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.StructureThe chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain. Variations are due to minor modifications of certain side groups.-XxItzAdiXxWhat is biotechnology

In the city of Epiland, public health agencies realized that the prevalence of cancer x, a very aggressive type of cancer, has been rising for the last 15 years. Some epidemiologic studies were conducted to find the causes of this type of cancer to be able to implement preventive strategies to reduce the mortality of this disease. One study conducted by researchers from the University of Epiland found that the attributable proportion of disease among smokers is 33.3% and the attributable proportion of disease among people that drink water with a high concentration of heavy metals is 75.4%.
Required:
a. Assuming that the population size is 1,000 people, the prevalence of smoking in Epiland is 60% and the percentage of people drinking water with a high concentration of heavy metals is 30%, calculate the total number of cases of cancer x that could be prevented if each one of the exposures were eliminated. What would be your suggestion to the public health agencies if they asked you which one of the exposures would have a greater impact on reducing the prevalence of the disease if it was eliminated?
b. Would your suggestion be different if the percentage of people drinking water with heavy metals were 10% and the prevalence of smoking remain the same? Which measure of association would be more efficient in helping you answer these questions?
