Answer:
intrinsic semiconductors
Explanation:
An intrinsic semiconductor is also known as a pure conductor. In such a semiconductor there are no impurities, that is why it is said to be pure.
It has some of these properties:
1. Electrical conductivity is only based on temperature
2. The quantity of electrons is the same as the number of holes in the valence bond
3. Electrical conductivity is not on the high side
4. These materials exist in their pure forms.
Answer:
one dependent and on or more independent variables are related.
The Neurons allow the body to move
A
Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.
<h3>
Does hydrogen have the highest specific energy?</h3>
- Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
- Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
- Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.

The plastic that pollutes water ways and ocean is a symptom of mismanagement that results throughout the biosphere in both terrestrial and aquatic environment.
Explanation:
We can reduce the microplastics by filtering tap water, avoiding usage of plastic containers, usage of beauty products with microbeads, limit eating of meat and fish.
The effective solution for for reducing this problem is giving up of plastics like avoid using bottles, plastic packaging, Don't use straws instead of that paper straws can be used.
The plastics are found everywhere in the environment and now it is found in sea water, fresh water, food and drinking water.
The products that contain plastics are tyres, synthetic clothing, tennis balls, laundry, tea bags and wet wipes.
