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: A. true
Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.
Hope this helps!!!

Not always, some proteins are used in a variety. <span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. </span>
The food web includes herbivores - (animals that eat plants), carnivores - (animals that eat other animals), and <span>Omnivore<span> - (an animal that eats both plants and animals)</span></span>
