** the bottom question “Liang is warming..”
Answer:
they move faster on average
Explanation:
temperature increase means the particles have more kinetic energy so they move faster
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.

Answer:
have two alleles for the gene
Explanation:
a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
b. Birds and sharks do not share a common evolutionary ancestor.
c. Having a bony skeleton did not provide an evolutionary advantage to sharks or ray-finned fish.
d. Rabbits and primates diverged more recently than crocodiles and birds.
Answer: a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
Explanation:
A cladogram is a diagrammatic representation of the phylogenetic relationship of recently evolved species with their common ancestors. The relationship is defined on the basis of genetic, molecular, morphological make up of the organisms. The node in the cladogram defines a divergence or difference between the two taxon.
Birds and amphibians share a more recent common ancestor than shark and birds because they can be seen lying closer at the terminal ends of the cladogram.
Answer:
Red blood cells (erythrocytes)
Red blood cells carry oxygen from your lungs to your tissues. They also bring carbon dioxide back to your lungs. Red blood cells make up almost half of your blood. The lifespan of a red blood cell is around 120 days
