What important discovery was made by columbia university researchers concerning carbon dioxide levels using data from biosphere 2?.
Answer:
Explanation:
Theorizing the chemistry of the calcification process, however, Biosphere 2 collaborators such as Marlin Atkinson of the University of Hawaii and Chris Langdon, Taro Takahashi, and Wallace Broecker of Lamont-Doherty Earth Observatory hypothesized that rising atmospheric CO 2 levels, which increase the partial pressure of CO 2 dissolved in seawater, might also exert important effects by changing the equilibrium of calcium carbonate and bicarbonate ions, making calcium carbonate less available to the living coral organisms.
According to this periodic table, how many differents types of atoms are there? Are they all the same size?
Answer:
Currently there are 118, it might be different from your table though. And no, atoms are not the same size.
Explanation:
No atoms are not of the same size unless they are the same element. Atoms increase in size as you go up on the Periodic Table because of the number of protons and neutrons.

Explain how an adaptation can enable an organism to survive a long-term environmental change. Describe and example to support your answer
Answer:
survival of the fittest
Some die, some survive. Those that survive to reproduce pass along their genes. Some survive by good luck. Others survive because they happen to have some quality that gives them a better chance to tolerate the environmental changes. Assuming those qualities are heritable, they’ll become more common in the genes of the surviving population. Eventually they’ll predominate. The population will have adapted to the changes.
With the exception of very primitive organisms, living animals have various senses including those familiar to us as sight, sound, touch, taste, and smell. Certain organisms have senses that we do not share. For instance, the class of snakes we call “pit vipers” have a specific organ that senses heat from prey animals, even in total darkness.
Bats use echolocation, bouncing high-pitched sound waves off of obstacles and prey alike. So do dolphins.
Many insects have the ability to smell only a few molecules of pheromones from potential mate
I took the question differently than everyone else, but it sounded to me like the OP was asking for examples of HOW organisms adapt, not two organisms that adapted.
Adaptation often begins with environmental monitoring systems. Lets say antibiotics are taken by a patient and a small amount gets in the area of a pathogen who is testing its environment. The pathogen detects the threat and begins to construct a genomic edit that can counter it. Unfortunately for us, cells are still more skilled with biochemistry than humans.
If you mean like to adapt in an instant, we humans release adrenaline to overcome stress and it actually makes us more prone to overcome stress. Another example its σ32 is the heat shock sigma factor in Escherichia coli, which it helps the bacteria to survive in a “heat shock”.
When we look at evolution, we often look at bacteria or animals that aren't really related to us, like the dinosaurs and how they evolved into avian animals.
There are two examples in human history that are great for this question.
Humans
Yup. People have made adaptations to the environment. Well, at least the environment that we create for ourselves.

Explain why increasing the trophic level always results in a decrease in organisms
(biomass) and energy.
Answer:
With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Answer:
Increasing the trophic level always results in a decrease in organisms (biomass) and energy because When energy decreases, it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Only a fraction of the energy available at one trophic level is transferred to the next trophic level. Typically the numbers and biomass of organisms decrease as one ascends the food chain.
A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of _______ energy for the stream ecosystem
A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
Flow of energy in the food chainMost of the energy that enters an ecosystem comes from solar radiation. The producing organisms that carry out photosynthesis absorb solar energy and fix it in chemical energy. When consumers feed on producers, part of that energy goes to these organisms, which, by serving as food for other living beings, also pass on part of their energy to them. This, therefore, flows, in a unidirectional direction, passing from a lower level to a higher one.
With this information, we can conclude that a leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem

In sp²-hybridized orbitals, how many p-orbitals remain to form multiple bonds?.
Answer:
1 remains
Explanation:
In sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.
What is Hybridization?Hybridization is a mixing of atomic orbitals which are of different shapes and have nearly same energy with give rise to same number of hybrid orbitals of same shape, equal energy and orientation so that there is minimum repulsion between these hybridize orbitals.
This is useful to explain the covalent bonds in organic molecules.
There are 3 types of hybridization which are based on the mixing of the orbitals
1. [tex]SP^{3}[/tex] hybridization- In this type of hybridization one s orbital and 3p orbital which are of same shell of atom mix together to form new orbital.
2. [tex]SP^{2}[/tex] hybridization - In this type of hybridization one s orbital and 2p orbitals mix together to form equivalent orbitals.
3. [tex]SP[/tex] hybridization - When 1 s and 1 p orbital goes in the process and mix together to form new orbital. The molecules who possess sp hybridization have linear shift with an angle of 180 degree.
Thus, in sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.
