Answer:
so yeah its B
Explanation:
The distribution of organisms of a species is constant with respect to time on the surface of the earth.
A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
Organisms of a particular species evolve with respect to time. A specific organism or species does not stay the same over a period of time. But they acquired constant changes over time. They are favored by the environment to produce fertile offspring.
Therefore, the distribution of organisms of a species is constant with respect to time on the surface of the earth.

Answer:
The distribution of organisms on the earth's surface is ultimately due to evolutionary change: Organisms or Species do not stay the same over time but are in a constant state of change as individuals. They are best able to live and reproduce within certain environments.

Plz give me brainliest.
Answer: "thick" "pink"
Explanation:
Approximately 90 percent of the water you ingest is absorbed by the small intestine.
The small intestine absorbs about 90 percent of the water you ingest. Water absorption is driven by the concentration gradient of the water, which is higher in chyme than in epithelial cells. Thus, water moves down its concentration gradient from the chyme into cells. The remaining water is then absorbed in the colon.

Explanation:
The blood plasma must be isotonic to maintain the health of red blood cells. Isotonic means that the concentration of solutes (like salts and proteins) in the plasma is the same as the concentration inside the red blood cells. This balance is crucial for several reasons:
1) Osmotic Balance: An isotonic environment prevents water from rushing into or out of red blood cells. If the plasma were hypertonic (higher solute concentration), water would leave the cells, causing them to shrink and become dehydrated. If it were hypotonic (lower solute concentration), water would enter the cells, causing them to swell and potentially burst. Isotonicity maintains the ideal osmotic balance.
2) Cell Shape and Function: Red blood cells have a characteristic biconcave shape, which increases their surface area for oxygen and carbon dioxide exchange. Maintaining an isotonic environment helps preserve this shape. In hypertonic or hypotonic conditions, the cells can become distorted, compromising their ability to transport gases effectively.
3) Hemoglobin Function: Hemoglobin, the protein responsible for carrying oxygen in red blood cells, relies on an appropriate ionic balance to function optimally. Changes in plasma tonicity can affect the ability of hemoglobin to bind and release oxygen.
In summary, an isotonic blood plasma environment is essential for the health and proper function of red blood cells, ensuring they can efficiently transport oxygen and carbon dioxide while maintaining their structural integrity.
