What are 5 basic differences between prokaryotic and eukaryotic gene structure?

the relationship between fig trees and fig wasps is facultative is true.

Mutualism is seen in the interaction between the fig tree and the wasp, which both deposits its eggs and pollinates the fig's flower. On the other hand, the fig permits the wasp's larva to feed on seeds in addition to shelter (fruit) for oviposition.

With their fig hosts, fig pollination wasps develop obligatory symbioses. About 75 million years ago, this mutualism first appeared. Female fig wasps fly considerable distances to transmit horizontally across hosts, in contrast to many other close symbioses that entail vertical transmission of symbionts to host progeny.

Answer:

urea

Explanation:

nitrogenous waste compounds such as urea are produced by the breakdown of various substances in the body which are then carried in the plasma to the kidneys to be excreted

Transporting a substance against its concentration gradient requires a transporter that uses energy or a co-transporter or countertransporter.

Transporting a molecule against its concentration gradient is called active transport. A primary active transport where ATP is used to transport a molecule against its concentration gradient. An example for this is the transport of Na⁺ and K⁺ by sodium-potassium pump.

Secondary active transport does not use cellular energy. But it is transported by using the energy gradient stored as a result of a primary active transport. The energy gradient developed by the sodium-potassium pump enables a cotransporter to transport glucose against its gradient. It is also called symport.

Countertransport or antiport carries one against the concentration gradient by using the energy gradient created by active transport of another molecule in opposite direction.

So transporting a substance against concentration requires a transporter that uses energy or a symport or an antiport.

The Nernst potential of a monovalent cation with a valence of +1 at 37°C, given the intracellular ion concentration of 10 mM and the extracellular ion concentration of 80 mM, is -62.9 mV.

The Nernst (equilibrium) potential is a measure of the electrical potential difference across a biological membrane that exists when a concentration gradient of ions is present. It can be calculated using the Nernst equation:

E = [tex]61 mV \times log(\frac{ [ion]out }{ [ion]in})[/tex]

Where E is the Nernst potential, [ion]out is the extracellular ion concentration, and [ion]in is the intracellular ion concentration.

Given the intracellular ion concentration of 10 mM and the extracellular ion concentration of 80 mM at 37°C, the Nernst potential can be calculated as:

E = [tex]61 mV \times log(\frac{80 mM}{10 mM})[/tex]

= -62.9 mV

This means that the electrical potential difference across the membrane is favoring the movement of the monovalent cation from the extracellular space to the intracellular space, in order to equalize the concentration gradient and establish an electroneutral state.

The curve represents an enzyme's reaction velocity without any inhibitor present is the curve where the reaction rate reaches its maximum level,

The  curve represents the velocity in the presence of a noncompetitive inhibitor is the curve where the reaction rate does not reach its maximum rate

the curve represents the velocity in the presence of a competitive inhibitor isthe curve where the reaction rate is inhibited at the start and manages to reach its maximum level.

Enzymes are biomolecules that function as catalysts, namely compounds that accelerate the process of a chemical reaction. Cells produce enzymes which are generally in the form of proteins as catalysts to help metabolism in cells which are concentrated in certain organelles where reactions take place. Enzymes will accelerate the rate of chemical reactions, namely changes in the concentration of reactants or products in a unit time. Without an inhibitor, the chemical reaction rate curve will run quickly to reach its maximum to form a new product as a result of the reaction.

Inhibitor is a chemical substance that can inhibit or slow down a chemical reaction. In non-competitive inhibitors the reaction inhibiting molecule will attach to the active site of the enzyme so that the substrate cannot attach. Therefore the reaction rate will decrease so that the curve will show the reaction will run slowly because it does not reach its maximum. Noncompetitive inhibitors slow down the overall rate of a chemical reaction.

While competitive inhibitor molecules will compete with the substrate for attachment to the active site of the enzyme. So the enzyme cannot produce the enzyme substrate complex. The curve will show that competitive inhibitors only inhibit at the beginning of a chemical reaction, in the end the reaction rate will reach its maximum level with the addition of many substrates.

Answer:

The process described is called primary succession.

Explanation:

Primary succession is the process by which a new community of organisms forms in a previously barren or lifeless area, such as on bare rock, sand, or lava. The process typically starts with the colonization of pioneer species, which are hardy and can grow in extreme environments, and gradually gives way to more complex and diverse communities. In the process of primary succession, the organisms modify the environment to create conditions that are more favorable to other organisms, which leads to the establishment of more complex and stable ecosystems.

In the given process, the windblown sand begins to accumulate and build small sand piles, which create a suitable environment for salt-tolerant grasses to grow. These grasses have a vast network of root systems that stabilize the sand dune and create a more stable and complex ecosystem. This is an example of primary succession, where the process starts with the colonization of pioneer species and gradually gives way to more complex and diverse communities.

Based on this information, water would move across the selectively permeable membrane from solution a (containing 50 percent glucose) to solution b (containing 25 percent glucose). There would be a net movement of water from solution A to solution B.

This is because of the osmosis principle, which states that water moves from a high-concentration area to a low-concentration area to balance the concentration of solutes on each side of the membrane.

Water would move from solution a to solution b to dilute the glucose in solution b and balance the concentration of solutes on both sides of the membrane because solution b has a lower glucose concentration than solution a. This movement of water would continue until either the membrane could no longer allow any more water to pass through it or until an equilibrium was reached in which the concentration of glucose on both sides of the membrane was the same.
