I would say the second answers, growth. This is because we need the nutrients and vitamins from food to help us grow, and keep us healthy.
The right answer is The cells are damaged.
Take the example of skin cells.
The skin consists of two tissues:
* the outermost, the epidermis, resting on a vascularized connective tissue,
* the dermis.
In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.
On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
Answer:Which is an adaptation?
Adaptation is the evolutionary process where an organism becomes better suited to its habitat. This process takes place over many generations. It is one of the basic phenomena of biology. ... Adaptation occurs because the better adapted animals are the most likely to survive, and to reproduce successfully.
What are the benefits of biodiversity to humans?
A healthy biodiversity provides a number of natural services for everyone:
Ecosystem services, such as. Protection of water resources. Soils formation and protection. ...
Biological resources, such as. Food. Medicinal resources and pharmaceutical drugs. ...
Social benefits, such as. Research, education and monitoring.Adaptation involves coping not only with the physical abiotic environment (light, dark, temperature, water, wind), but also with the complex biotic environment (other organisms such as mates, competitors, parasites, predators, and escape tactics of prey).
