There is no relationship between lifespan and shape or size of the organism. Lifespan is independent of shape or size. For example.... lifespan of crow and parrot. Both r of same shape and size but there is difference between their respective lifespans.

Shalini Tiwari 8 years, 1 month ago

Cattle egrets follow grazing cows and eat the flies and bugs that tend to bother the cattle. The movement of foraging livestock also dislodges various insects from the field, which cattle egrets feed on. This type of symbiotic relationship is called commensalism

Difference between fragmentation and regeneration

Posted by Amrita Phogat 4 years, 9 months ago

CBSE > Class 12 > Biology

1 answers

Sia ? 4 years, 9 months ago

Fragmentation	Regeneration
During the process of fragmentation, an organism splits into fragments and each of these fragments develops into individual organisms.	During the process of regeneration, an organism regrows a particular body part in case there has been certain damage to it.
Each fragment forms into a new organism.	There are no new organisms formed during this process.
The process of fragmentation is only seen in organisms that have the same simple body organisation and are multi-cellular.	The process of regeneration is seen in multi-cellular organisms that have complex body organisation.
Fragmentation is only limited to certain organisms.	Regeneration, however, is seen in all organisms either up to a certain extent or completely.
This process does not involve the use of specialised cells.	This process involves the use of specialised cells in proliferating and forming a cell cluster, which then proceeds to form various other kinds of cells and tissues.
Fragmentation is only seen in invertebrates.	Regeneration is seen both in vertebrates and invertebrates.
Fragmentation is a process of reproduction (asexual).	Regeneration is a process of reproduction as well as regeneration of lost body parts, tissues or cells.
This process is generally seen in plants, especially non-vascular ones.	This process is generally seen in animals as compared to plants.
Fragmentation is highly dependent on the structural complexity of an organism and can occur as a natural process or may result from the action of a predator.	Regeneration is seen across all living organisms and is mostly the result of an action or damage to the concerned body part.
Organisms like sea anemones, sponges and flatworms undergo the process of fragmentation.	The tail of a lizard, limbs of an octopus or regrowth of blood vessels in humans are some instances of regeneration.

DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. Small amounts of dystrophin are present in nerve cells in the brain.
