Description of thigmotropism is given below.
Explanation:
1. Thigmotropism is a plant’s response to touch.It is a plant’s response to an external stimulus.It can occur quickly or slowly.Thigmotropism may involve the closing and opening of plant leaves.
2. Thigmonasty or thigmotropism can be define as the response of touch shown by the plants. Here, touch is the external stimulus. It can be define as the movement of the plant parts in response to the external stimulus that is contact or touch. It is also known as Haptotropism. The plant may change it's orientation, shape and size of the plant parts.
3,The thigmotropism can be positive or negative depending upon the visual response shown by the plants. The response shown by the plants is generally fast but may be slow. This response is shown by the plants in cases of danger of herbivory.Some plants like Mimosa pudica or touch me not plant shows thigmotropism by closing their leaves on touch
Answer:
selective permeability
Explanation:
The property or characteristic of cellular membrane to allow certain substances to pass through the cell is known as selective permeability. The movement of molecules and ions across the cell can be active or passive.
C
in the first paragraph a fact is challenged
and the second one provides an example
There are 6 molecules of O2.
"O2" is the formula for one molecule oxygen, which has 2 atoms.
The subscript (small) "2" tells you how many atoms are in the molecule.
The coefficient is the big number tells you the number of molecules.
In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).
Mutations occur in both germ cells and somatic cells, but the consequences of both are different. Mutations in somatic cells are called somatic mutations. In this case, if mutations occur in somatic cells, they can develop diseases, or start the cancerous process. They give rise to all non-germ line tissues because they do not occur in cells that give rise to gametes.
In addition to this, a process known as teratogenesis may occur, which may end up with congenital defects, disorders, and syndromes. During the process, genetic changes may cause alterations in the baby during the embryonic phase of the pregnancy.<span>
