Answer:
Allows to reabsorb water.
Explanation:
The kidney uses energy to generate an osmotic gradient (that is the difference in the concentration of two spaces separated by a membrane). This gradient allows the kidney to reabsorb water, and so create more concentrated urine or less concentrated, depending on how hydrated the body is.
<span>The organism enables itself to adapt to the environment's harsh conditions.
Adaptation is the unique trait that animals and plants have in order to survive through the evolution of time. Some animals that live in cold ranges around the world are an example of this adaptive trait. Alpine animals that are found in mountain ranges are exposed to the very cold temperature and the ultraviolet wavelengths of the sun. Most alpine animals have extra layers of fat and fur to protect them from the harsh environment. They also have shorter limbs (e.g. legs, ears, tail) to prevent heat loss. </span>
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
Answer:
Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly.
