The maintenance of relatively constant internal environment of an organism is called Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.
The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the homeostatic control.
The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors send signals to the brain ,and the organisms responded to these with the example above.

Permits in the cap and dividend policy are issued for _______ production. a. carbon dioxide b. timber c. water pollution d. plastic
Answer:
the answer is A.. I think
Permits in the cap and dividend policy are issued for carbon dioxide production. Therefore, option (A) is correct.
What is The cap and dividend policy?The cap and dividend policy is one potential approach to lowering carbon emissions and slowing the progression of climate change. The way it works is by first establishing a limit on the total amount of carbon emissions that are permissible within a given time period, and then handing out permits to businesses in proportion to the amount of emissions that they are responsible for producing.
If a company emits fewer greenhouse gases than their allotted amount, they have the option of selling their unused permits to businesses that have a demand for more. This results in the creation of a revenue stream that can be distributed to individuals in the form of a dividend, as well as a financial incentive for businesses to reduce the amount of carbon emissions they produce.

3. Every species of fig has its own species of fig wasp to pollinate its flowers. Without the fig wasp, there would be no fig seeds. Without the fig, the wasp could lay no eggs. What is the relationship between these two organisms?
Answer:
obligate mutualism
Explanation:
A type of mutualism in which the species involved are in close proximity and interdependent with one another in a way that one cannot survive without the other.
The relationship between the fig wasp and the fig tree as described in the illustration would be symbiosis.
A symbiotic relationship is a form of mutualistic relationship between two organisms in which both of them benefit.
The fig wasp benefits the fig tree by helping with the pollination of their flowers. Without pollination, fertilization and seed production become impossible.
The fig tree, in return, benefits the fig wasp by providing a conducive environment for egg-laying. Without this environment, the fig wasp cannot lay eggs and the population of fig wasp will dwindle.

Which are the two most important factors determining the movement of ions across the cell membrane?
Answer:
The two most important factors determining the movement of ions across the cell membrane are: the permeability of the molecule in the membrane, and the existence of an energy source.
Explanation:
Ions are charged molecules that, no matter their size, cannot pass through the membrane by simple diffusion because of the nature of the lipid bilayer of the membrane.
Ions can move across the cell membrane in two different ways: passive transport and active transport. The disparity between these two relies on the usage of ATP (energy) - passive transport doesn't need ATP while active transport does. This is where the availability of a source of energy is important, because if there isn't, then active transport is impossible.
On the other hand, ions can move through the cell membrane without the use of energy by diffusing through the membrane with the help of specific membrane proteins that form channels for ions to pass through - and this is where permeability matters: if the cell membrane is permeable to a specific ion, it means that it has opened channels for that ion to use; and this ion will move from one fluid to the other (intracellular or extracellular) following its concentration gradient (for example, sodium is poorly concentrated in the inside of the cell, while is highly concentrated on the outside - this means that sodium will go through the membrane to get inside the cell and even the concentrations between the two fluids, but only if the membrane is permeable to sodium!).

Water molecules may sometimes gain or lose an oxygen atom to become ions, which are held together by ionic bonds. C. Water molecules are held together by hydrogen bonds, which are attractive forces stronger than ionic bonds. D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds.
Answer:
D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds
Explanation:
Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question. This unique properties can be attributed to the HYDROGEN BONDING that holds the molecules of water together.
However, the hydrogen bonding of water molecules is an attractive force that is quite WEAKER than ionic or covalent bonds but it holds water molecules tightly to one another.

Oxygenic photosynthesis at first caused a mass extinction, but also allowed complex life on Earth to develop. In what ways does free oxygen allow complex life
Answer:
Oxygen would be played a key role in evolution of complex organisms because this molecule is required to efficiently produce chemical energy during cellular respiration
Explanation:
Chloroplasts originated from endosymbiotic cyanobacteria 1,500 million years (mya) ago. Like chloroplasts, mitochondria originated from cyanobacteria, and also approximately at the same time. Mitochondria are organelles capable of generating energy by burning oxygen during cellular respiration (aerobic respiration). During this period (1,500 mya), complex cells became able to efficiently produce energy by using oxygen in aerobic reactions, which can be attributed to the emergence of mitochondria. Interestingly, it has been shown that during the next 500 mya, different groups of organisms composed of more than 50 different cell types evolved (including algae, fungi and early animals). Therefore, it is possible to hypothesize oxygen would be a critical molecule without which complex organisms couldn't evolve.
Oxygen played a vital role in evolution of complex life because the transfer of electrons from organic molecules to oxygen released a large amount of energy, thus resulting in efficient production of chemical energy during cellular respiration.
For life to exist, energy must be available and abundantly so, in order to carry out the vast array of activities that makes life possible.
At first, only simple life forms which did not depend on oxygen existed. This life forms were collectively known as anaerobes.
Because the electron acceptors they used then were not very efficient in accepting electrons during the oxidation of organic compounds to produce energy, life remained in simple forms as microorganisms.
However, as the atmosphere became progressively richer in oxygen, some anaerobic microorganisms evolved who were able to obtain energy by passing electrons to oxygen.
Endosymbiotic associations which eventually became permanent between aerobic and anaerobic microorganisms gave rise to structures such as the mitochondria, plastids and chloroplasts.
This ability to effectively use oxygen as electron acceptors to produce energy as in mitochondria as well as produce oxygen as in chloroplasts led to the appearance of more complex life forms who were able to carry out more complex life activities due to efficient production and utilization of energy. These life forms include the algae, fungi and early multicellular animals.
Therefore, it can be concluded that oxygen played a vital role in evolution of complex life because the transfer of electrons from organic molecules to oxygen released a large amount of energy, thus resulting in efficient production of chemical energy during cellular respiration.
