Explain the mechanism of nematocyst in Portuguese man of war?

Biology

Katyanochek1 [597]3 years ago

Answer:

Scientists believe that man-of-wars spawn together in large numbers, with each colony (being either all male polyps or all female polyps) releasing gametes into the water to be fertilized. The resultant larvae then each go through asexual budding to produce a new man-of-war colony.

Starfish are able to reproduce both sexually and asexually. In an area of the ocean that is gradually changing due to increasing
belka [17]

Due to the increasing temperature in ocean it is more advantageous for start fishes to reproduce asexually because they can regenerate via a process called fragmentation.  

In fragmentation, a part of arm or a part of disc is separated from the parent body and grows into a complete new organism; an individual star fish.  

Moreover, regeneration is the ability of an organism to renew, or re-grow any part of the body, makes it resilient to environmental fluctuations.

Negative feedback
zhuklara [117]

Answer:

b. Works within an upper and lower range

c. " Is regulatory. "

d. Is very common in biological systems

Explanation:

Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.

For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.

Why do you feel fatigue in your forearm rather than your fingers?
Arisa [49]
Because your forearm has muscles while your fingers don't actually have muscles. 

In your fingers you only have tendons which don't contribute to the feeling of fatigue. This is different for your forearms because there you would usually find muscles and which, when worked enough, build up lactic acid that we're feeling as fatigue.
