Answer:
D. Both a and b
Explanation:
The difference in ion concentration between the intracellular and extracellular fluids in a cell is due to both active ion transport and passive diffusion of ions.
The difference in ion concentration between the intracellular and extracellular fluids in a cell is primarily due to both active ion transport and passive diffusion of ions. Active ion transport refers to the movement of ions across the cell membrane using energy, such as through ion pumps or channels. Passive diffusion, on the other hand, occurs when ions move down their concentration gradient without the need for energy.
For example, the sodium-potassium pump actively transports three sodium ions out of the cell for every two potassium ions it brings in. This creates a higher concentration of potassium ions inside the cell compared to outside. Meanwhile, passive diffusion allows ions like chloride, calcium, and potassium to move across the cell membrane through ion channels, either facilitated by a concentration gradient or electrical potential.
In summary, the difference in ion concentration between the intracellular and extracellular fluids in a cell is due to both active ion transport and passive diffusion of ions.

B.Living organisms create order by using energy from the sun.
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Answer:
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Explanation:
Entropy is a concept of thermodynamics that measures the disorder of particles in a physical system. Living organisms create some disorder through reactions that generate waste heat so that through heat-shaped energy, organelles capable of generating macromolecules, organelles, cells, tissues, and higher-order complex structures are ordered.
(B.) carbon dioxide
C. oxygen
D. hydrogen
carbon dioxide?
Answer:
The correct answer would be C. Bb.
Heterozygous condition refers to the genotype in which a gene contains two different alleles.
In contrast, homozygous refers to the condition in which gene contains two identical alleles.
For example, TT and tt are homozygous genotypes whereas Tt refers to the heterozygous condition.
Similarly, genotype Bb consists of two types of alleles B and b. Thus, it represents a heterozygous condition.
Answer: atmospheric, carbon dioxide
Global climatic change is directly linked with the changes in the atmospheric conditions, this is because of increase in the carbon dioxide levels in the atmosphere. Atmosphere is the distinct layer of gases in the planet earth. Atmosphere regulates climatic change in a region. Carbon dioxide is a hot and harmful gas affects the quality of respirable air, and increasing the temperature of global climate.
Answer:atmospheric, carbon dioxide
