Why might (mostly) boneless creatures, like jellyfish, sea slugs, squid, and octopuses, fare especially well underwater? What is
vagabundo [1.1K]

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.

What is the effects of body size of urination flow/time
natali 33 [55]

Answer: There are two factors that determine the urine flow rate during an osmotic diuresis: the rate of excretion of effective osmoles in the urine and the effective osmolality of the interstitial compartment of the renal medulla.

The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day).

Explain with examples three types of nastic movements
Nesterboy [21]

1. Tropisms are directional movements or growth response of a plant to the stimulus. In nastic movements, the response of the plant is non-directional. An example of tropism is thigmotropism, which is a growth response to the touch stimulus.

2. Nyctinasty is the nastic movement of plant parts such as leaves and petals in response to darkness.

3. Thigmonasty is a form of nastic movement (of a plant or a fungus) as a response to touch or vibration.
