In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.
In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.
Because the organism is distributed across the world, and isn't seen anymore, scientists can conclude tat they must have evolved. They can compare one species to the fossils they may have found, and determine that they were related. Then by looking at the species on another part of the world compare the same fossils to other animals and determine that they are similar, sharing a common ancestor.
Answer:
The term secretion refers to the cell that releases a substance into the extracellular space.
Explanation:
When a cell or organ or gland produce and secretes substance in to extracellular space,this biochemical process is called as secretion.
The secretory products may be hormone, enzymes etc.
This process facilitates the movement of material from one place to another place.
For example, Pituitary gland produce and release prolactin hormone that induces breast cells to produce lactation during sucking process done by baby.
Pituitary gland also secrete different hormones that acts on different glands like adrenal, testes, ovary, thyroid gland etc that in turn produce different hormones like adrenaline,testosterone,estrogen,progesterone, TSH,T3, hormone etc.
