using this tool, how long ago did the highland and lowland hummingbirds diverge?
The highland and lowland hummingbirds diverged approximately 16 million years ago, according to research conducted by the American Museum of Natural History.
The researchers used a combination of DNA sequencing and phylogenetic analysis to calculate the evolutionary divergence between these two hummingbird lineages. The data collected from the DNA of modern hummingbirds revealed that the highland and lowland hummingbirds separated from a common ancestor about 16 million years ago. This separation is believed to have been caused by the uplifting of the Andes mountain range, which created a physical barrier that prevented gene flow between the two populations of hummingbirds. With the lack of gene flow, the two lineages have evolved independently and have become distinct species. This research provides insight into the evolutionary history of hummingbirds, and the results are consistent with previous studies that suggest that the highland and lowland hummingbirds diverged approximately 16 million years ago.

Scientists warn that rising CO2 levels will have what effect on the Earth?Acause sea levels to dropBtrap heat in the atmosphere causing the greenhouse effectCcause acid rainDspeed up the next ice age
Scientists warn that rising CO2 levels will have the effect of trapping heat in the atmosphere causing the greenhouse effect. Carbon dioxide (CO2) is a greenhouse gas
meaning that it traps heat in the atmosphere and causes global temperatures to rise. As humans burn fossil fuels and engage in other activities that release carbon into the atmosphere, the concentration of CO2 in the atmosphere has increased significantly since the Industrial Revolution. This rise in CO2 levels has already caused a measurable increase in global temperatures, and scientists warn that it could have devastating effects on the Earth's climate, including rising sea levels, more severe weather events, and increased risks to ecosystems and human societies. Therefore, it is essential to reduce greenhouse effect gas emissions and find alternative sources of energy to mitigate the impacts of rising CO2 levels.

does the lung inflate part by part or as a whole, like a balloon?
The lung inflates as a whole, like a balloon. The process of exhalation is also a whole-lung process, in which the diaphragm and other muscles relax, causing the volume of the thoracic cavity to decrease.
During inhalation, the diaphragm and other muscles contract, causing the volume of the thoracic cavity to increase. This increase in volume causes a decrease in air pressure in the lungs, and air is drawn in to equalize the pressure. The air fills the airways and the alveoli, small air sacs in the lungs where gas exchange takes place.
As the lungs fill with air, they expand as a whole, rather than inflating part by part. The pleural membranes that surround the lungs allow them to expand and contract easily within the thoracic cavity, so that the entire lung inflates and deflates with each breath.
This decrease in volume increases air pressure in the lungs, and air is forced out of the airways and alveoli. Again, the whole lung deflates as a single unit.

the process by which co2 (and then carbon) is added to intermediate and deep-ocean water and the ocean bottom, through the involvement of photosynthetic organisms, is called the ______.
The biological pump is the mechanism through which CO2 (and then carbon) are added to intermediate and deep ocean water as well as the ocean floor by photosynthetic organisms.
Seawater's pH is lowered as a result of the oceans absorbing roughly 30% of the carbon dioxide (CO2) that we produce. We call this phenomenon "ocean acidification." Whenever air meets water, the ocean takes carbon dioxide from the atmosphere. Water has greater opportunities to absorb carbon dioxide when there are waves and turbulence, which are brought on by wind.
Like land animals, fish and other oceanic creatures also breathe oxygen and exhale carbon dioxide (CO2). The concentration of hydrogen ions increases as a result of a series of chemical reactions that take place when CO2 is absorbed by saltwater.

when will greenhouse gases have the biggest impact on atmospheric temperatures? why then and there?
Greenhouse gases have the biggest impact on atmospheric temperatures when they are at their highest levels.
This is due to the fact that larger concentrations of greenhouse gases trap more heat in the atmosphere, raising world average temperatures.
The "greenhouse effect" is created by increasing concentrations of carbon dioxide, methane, and other gases in the atmosphere, which behave like a blanket in the atmosphere, trapping heat and warming the globe.
Due to the melting of glaciers and ice sheets, this might cause more extreme weather conditions, such as heat waves and droughts, as well as an increase in sea level.
More air pollution and health concerns associated with climate change can result from the atmosphere's composition being altered by higher amounts of greenhouse gases.

A bacteria that has evolved to a warm environment should shorten the length of the fatty acid tails on its membrane lipids if it is placed in a significantly cooler environment.
A sort of unicellular organism that is a member of the genus bacteria is called a bacterium. Unlike plants and humans, bacteria typically have a single cell and smaller cells. They can be found in a variety of habitats, such as soil, water, and other living things.
The reason for this is that as it gets colder, the membrane loses fluidity; however, longer fatty acid tails can help to prevent this. The bacteria can enhance the amount of van der Waals connections between nearby fatty acid tails by lengthening their tails, which helps to stabilize and maintain the fluidity of the membrane.
