Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
a) Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
b) If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

why is global warming dangerous?
Answer:
Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.
Explanation:
Answer:
The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats. Unless you wanted any of that to happen you need to care about saving the planet however you can.
Explanation:
How are photosynthesis and cellular respiration connected as a cycle?
Answer:
Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off).
glucose + oxygen + (energy) → carbon dioxide + water
C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O
Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (thus making it exothermic).
carbon dioxide + water + energy → glucose + oxygen
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
As you can see from the equations, they are essentially the reverse of each other.
Another difference is how they are used. Respiration occurs in the mitochondria of all living cells, whereas only plants photosynthesize.
In plants, they make their own glucose using the sun's energy, then respire to allow them to use the glucose for the energy they can use. The glucose can also be stored and used in many other ways other than in respiration.

How is the process of protein synthesis similar to the process of programming a computer? How is it different?
Answer:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. ... Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome.
Both the synthesis of proteins and computer programming entail a series of instructions that lead to a particular output. While programming a computer and making proteins have some parallels, they are essentially separate activities that take place in different domains and use different tools and procedures.
What are the similarities and differences between proteins and computer programming?Similarities between proteins and computer programming:
Protein synthesis and computer programming both involve a series of instructions that are carried out in a particular order to get the intended result.Both processes need input data to produce output, and both processes require input data.Both methods rely on a language or code that is used to specify the instructions.Differences between proteins and computer programming:
Protein synthesis is a biological process that takes place inside of cells, whereas computer programming is a human-made activity that takes place inside of a machine.DNA and RNA are used in protein synthesis, just as a programming language is used in computer programming.Ribosomes, tRNA, and amino acids are used in protein synthesis to create proteins, whereas compilers, interpreters, and machine code are used to create programme for computers.Therefore, both the synthesis of proteins and computer programming entail a series of instructions that lead to a particular output.

Explain the role of aquaporins in the rapid movement of water through some cells
Answer:
In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.

What is the molecule called that all living things use for immediate
useable energy?
ATP, Sugar,fat, All of these
Hello there!
I think ATP would be the answer in this instance. See, ATP is the pure form of energy that cells prefer to use. Sugars and fats are good for energy, too - but sugars and fats must be converted into energy before use. So ATP is the only energy source listed that doesn't need to be metabolized before the cell can use the energy.

What is the impact of developing and using rock, mineral, and energy resources on earth's living and non living systems
Answer: The use of rock, mining and energy production contaminates the environment by affecting the abiotic land mass. And therefore, by contaminating the habitat, the living beings that live there are harmed.
Explanation:
Mineral and rock extraction, transport and processing comprise actions that produce environmental impacts because it produces a certain disturbance to the surface and underlying strata, as well as to aquifers. These impacts can be short-lived, lasting as long as the mine is operational, or they can persist after mine development has been completed.
Major impacts include:
Contamination of soil, vegetation, drainages, rivers and groundwater aquifers contamination from leaking tailing piles and slurry ponds. If not properly treated, effluent from surface or subway mine water disposal can be highly acidic, and will contaminate surface waters and shallow groundwater with heavy metals, nitrates or oil from equipment, reducing local water supplies. During surface mining, movement and stockpiling of overburden, constructions or covering of soils alter rivers, drainages and coastal areas. Surface disturbance caused by access roads, pits, and site preparation.Noise and emissions from the operation of equipment.Air pollution, atmospheric dust from traffic, excavation, drilling and site clearing. Atmospheric particulates come from blasting, excavation and earth moving, transportation or any operations that occur on the surface of subway mines.Removal of rock strata can disrupt the continuity of the local aquifer, and cause interconnections and contamination between groundwater.Both surface and subway mining include a drainage of the mine area and discharge of mine water, the removal and storage/disposal of large volumes of waste and the transfer and processing of minerals or construction materials. This requires the use of diesel or electric mining and haulage equipment. Transportation of ore within the mine area and to processing facilities may use trucks, conveyors, rail, polyduct or conveyor belt which are vehicles that emit large amounts of carbon dioxide.
Processing plants may be located in mountainous regions and so may have difficulty disposing of production wastes and other pollutants. They may then end up disposing of them in rivers or coastal waters.
The land at the surface of the mines will be unstable, there will be fracturing and subsidence, it will modificate soils, vegetation, rivers, wildlife habitat, wetlands, causing a temporary or permanent loss of land productivity, and contamination of soils due to mineral materials and toxic substances.
Also, the production and use of energy is the main cause, together with transportation, of greenhouse gas emissions, the gases responsible for climate change. Consequences of climate change are increased temperatures, rising sea levels and reduced rainfall.
The current model of generation, transport and consumption, absolutely dependent on fossil fuels, is unsustainable. The chemical products emitted, mainly from coal and oil-derived thermal power plants, are transported by the wind and deposited by rainfall thousands of kilometers away from their origin, causing "acid rain", which is the cause of the deterioration and destruction of forests, lakes and other ecosystems. Another example are the Nuclear power plants which produce high-level radioactive waste (long-lived, highly radioactive), which poses a constant threat to the environment due to the current inability to manage it.
Thus, the use of rock, mining and energy production contaminates the environment by affecting the abiotic land mass. And therefore, by contaminating the habitat, the living beings that live there are harmed.
The impact of developing and using rock, mineral, and energy resources will be:
loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil.
Impact of Minerals:They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Soil, rocks, and minerals provide essential metals and other materials for agriculture, manufacturing, and building.
