Answer:
The species that develop in aquatic environments, need to be able to have an adequate locomotion and according to the hydrostatic pressure in the water, which this pressure has the opposite direction to gravity in terrestrial life.
Explanation:
Vertebrates that have a skeleton are accustomed to gravitational forces, and this bone structure is what allows adequate locomotion to perform movements as a function of the force of earth's gravity, in water the force of gravity has no effect, since that the hydrostatic force predominates, which the direction is opposite to the gravitational forces.
Amorphous bodies, with few solid structures, not bony, make them better adapt to movements in water masses that are promoted by hydrostatic forces.
Answer:
4, 2, 1, 5, 3
Evolution- it is the emergence of the present forms of organisms gradually over a long period of time from pre-existing ones.
↓
Microevolution-one trait changes from generation to generation
↓
Natural selection- it is a process where nature selects those organisms that are well adapted to the prevailing environmental conditions to survive and reach reproductive maturity and pass on favorable traits to offspring.
↓
Sexual selection- natural selection that arises through preference by one sex for certain characteristics in individuals of the other sex.
↓
Intrasexual selection-selection within the same sex, individuals of one sex can be compete directly mates of the opposite sex
The word that goes on to the gap is "cells"
Hope it helped!
Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
