Yes, democracy can have both representative and direct characteristics at the same time.
There are many both-elements democracies in the Middle and Western US states. On the one hand, they have legislatures made up of Representatives and Senators, which is obviously a representative democracy because the representatives are chosen by their constituents and serve as their representatives in the legislature. Many of these states also have the referendum and initiative processes. In places like South Dakota and Nebraska, voters can use the initiative process to collect signatures and put possible laws on the ballot; if the proposed law achieves a majority vote, it becomes a law and cannot be vetoed. This is a direct democracy since the voters are deciding whether legislation should be passed without using their representatives.

How is/are the relevant variable(s) of fick's law optimized by the countercurrent oxygen exchange in lugworm gills?
(P high - P low) is re-established to optimize the variable(s) of Fick's law.
According to Fick's law of diffusion, particles subject to random thermal motion have a tendency to move from an area of higher concentration to an area of lower concentration. Fick's diffusion law, which asserts that the diffusion flow is proportional to the concentration gradient, mathematically describes three-dimensional diffusion.
The diffusion process is explained by Fick's law of diffusion (movement of molecules from higher concentration to lower concentration region). Adolf Fick first explained Fick's Law of Diffusion in 1855. Normal diffusion, often known as Fickian diffusion, is a diffusion process that complies with Fick's rules. An abnormal diffusion process also referred to as non-Fickian diffusion, defies Fick's rules.
According to Fick’s law of diffusion,

In the __________, the reproductive cycle entails alternation of generations; a spore-producing generation alternates with one that produces eggs and sperm.
Answer:
In the ferns, the reproductive cycle entails alternation of generations; a spore-producing generation alternates with one that produces eggs and sperm.
Explanation:
A fern is a specific type of vascular plant which reproduces through spores rather than seeds or flowers. Ferns are plants with roots, stalks, and leaves, much like blooming plants. Unlike blooming plants, unfortunately, ferns lack flowers and seeds and rather than reproduce sexually by secreting microscopic spores or occasionally by vegetative means, as is the case with the walking fern.
In previously, many vascular plants that yield spores were loosely classed with ferns and referred to as "fern allies." Surprises concerning the connections between ferns and their companions have been revealed by recent genomic investigations. First, ferns and horsetails seem to have a lot in common. Horsetails are really now included in the fern family. Second, the flora club moss as well as quillworts, which are sometimes referred to as "fern allies," are in no way related to ferns.

1. how are positive ions formed (what is gained or lost)? use potassium (k) as an example. how many protons and electrons does a neutral atom of potassium (k) have? how many protons and electrons does a positive ion of potassium (k) have?
Positive ions are formed when electrons are lost, for example, Potassium ion, K⁺ is formed when a Potassium atom, K losses one electron. A neutral atom of Potassium (K) has 19 protons and 19 electrons, and a positive ion of Potassium (K⁺) has 19 protons and 18 electrons.
Ions are charged particles formed when neutral atoms loss or gain electrons. When electrons are lost, positively charged particles called cations are formed, and when electrons are gained, negatively charged particles called anions are formed. Electropositive elements are more likely to form cations. Potassium (K) losses one electron in order to obtain a stable configuration, forming Potassium ion (K⁺).
For all neutral atoms, the number of protons is always equal to the number of electrons. The number of protons is the same as the atomic number. Potassium (K) has an atomic number of 19, thus it has 19 protons. Since Potassium (K) atom is a neutral atom, it will also have 19 electrons.
However, Potassium ion (K⁺) has lost one of its electrons, so it will have 18 electrons instead of 19. Therefore, Potassium (K) has 19 protons and 19 electrons, while Potassium ion (K⁺) has 19 protons and 18 electrons.

The SNS is a part of the central nervous systems which are responsible for producing reflex cardiovascular system modifications as well as localised changes (such sweating in reaction to a rise in body temperature). The defence response, which is a broad rapid reaction, is produced when the SNS is fully engaged under stress. Large amounts of adrenaline are released from either the adrenal gland during this response, which is also characterized by a rise in cardiac function, heart rate, as well as skeletal muscle dilatation as well as pupillary dilation, bronchial dilatation, and piloerection.

If a solution has a pH of 7.5, what would its new pH be if the concentration
of H₂O* ions in the solution were increased by 100 times? Explain your reasoning
The correct answer is pH of 5.5 Increasing the H3O+ by 10 fold decreases the pH by 1 unit so an increase of 100 would decrease the ph by 2 units .
When the concentration of hydrogen ions in a solution increases by a factor of ten, the pH of the solution decreases by one. The acidity of a solution is thus defined as its hydrogen ion concentration [H+] expressed as the solution pH. The pH of a solution is more precisely defined as the negative log of the hydrogen ion concentration: pH=log[H+].
