Answer:
Directional -------- TRUE ✔
Explanation:
Directional selection is a kind of natural selection that as the phenotype (the observable characteristics) of the species moving towards an extreme instead of the mean phenotype or the other extreme phenotype.
This type of selection is observed in environments that experienced variation over time as in weather, climate, or food availability. It gives a population bell curve for a certain trait that moves either in the left or right direction as seen in the attached image.
It is important to note that animal predators can also lead to directional selection as the slower animals in a prey population tends to be killed and eaten as the directional selection will continually skew the population in the direction of the faster animals.
Answer:
isosmotic; isosmotic; hyperosmotic; hypoosmotic.
Explanation:
The osmotic pressure is important for the flow of molecules in the different compartments of the different organs of the body. The osmosis process is energy independent process that transfers the molecules along the concentration gradient through the semi permeable membrane.
The plasma and tubular fluid are isoosmotic with each other means they have same osmotic pressure when it enters the Bowman's capsule that maintain their osmolarity. The fluid still remains isoosmotic when enters at the beginning of loop of Henle. The fluid then becomes hyperosmotic because it shows a large amount of difference between the solutes as compared with the plasma fluid and contains large amount of ions at the tip of Loop of Henle. The fluid then become hypoosmotic because now it contains few solutes as compared with the plasma at the deginning of the distal convoluted tubule. This osmolarity difference helps in the production of urine.
Thus, the correct answer is (c).
Answer:
Las aletas ubicadas en diferentes lugares del pescado sirven para diferentes propósitos, como avanzar, girar, mantener una posición erguida o detenerse. La mayoría de los peces usan aletas al nadar, los peces voladores usan aletas pectorales para deslizarse y los peces rana las usan para gatear.
