Answer:
Homeostasis is an outcome of gene regulation.
Explanation:
This is because gene regulation serves to ensure that protein activity is kept within a narrow range.
Answer:
A
Explanation:
A) adaptations that cause a disadvantage to the species are selected against and do not become common in the population.
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.
Weak acids and bases undertake reversible reactions. For example, carbonic acid: H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq).
The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents (A and B or C and D) and the equilibrium constant, K. The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction.[2] So, when the free energy change is large (more than about 30 kJ mol−1), then the equilibrium constant is large (log K > 3) and the concentrations of the reactants at equilibrium are very small. Such a reaction is sometimes considered to be an irreversible reaction, although in reality small amounts of the reactants are still expected to be present in the reacting system. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction
Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.
