I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)
Answer:
Explanation:
1. Visual design
Users can be distracted by the lack of visual design on a prototype because wireframes and other low-fidelity prototypes are very basic. This can cause users to comment on the lack of design and colour and distract both themselves and the researcher from the true goals of the project. The extent of this challenge depends on the level of detail within the prototype.
How to get around this: Ensure the user is aware at the start of a session that the website they are about to view is at an early stage of development and so does not look and feel like they may expect. The research may need to be explicit with some users and point out it is not the visual design that we are interested in for today.
2. Partial journeys
Prototypes often cover only partial user journeys, meaning that users may have to be dropped into a journey at a specific point and may lose the context of the overall task or what they would be coming on the site to do.
How to get around this: As well as creating tasks which set the context, consider including some time at the beginning of the session for users to explore the prototype as they would normally do on that website/app, without giving them long enough to discover the prototype journeys. Introductory questions can also be asked at the start of the session to position the user in the right frame of mind for what the prototype will allow them to do, therefore helping to provide some context alongside the task wording.
Answer:
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.

Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
