Answer:
Some protists have one or more flagella, which they rotate or whip: these are typically euglena. Others are covered in rows or tufts of tiny cilia that they coordinately beat to swim—typically paramecium.
I hope this helps I found this on google.
During ELECTRON TRANSPORT CHAIN.....
Plasma membrane is the structure which covers up the uptaken molecule.
<h3><u>Explanation:</u></h3>
Uptaking of nutrients from the surrounding needs to be very appropriate for the cell to obtain nutrition, as well as to maintain cell immunity. In case of simpler molecules like glucose etc, the molecules are taken inside the cell by means of specific channels or transport proteins. In case of complex molecules, cells prefer to perform endocytosis - either phagocytosis for solid ones, and pinocytosis for liquid ones.
When the cell finds something which can be taken in, it projects a fold of cell membrane towards the liquid which surrounds part of the liquid, or fully. This cell membrane then presents a depression which covers up the liquid. Then the margins of the depression come closer and ultimately fuse, leaving the liquid inside the cell enclosed with a part of cell membrane. This then fuses with a primary lysozome to form a digestive vacoule, a secondary lysozome, a residual body, and ultimately gets excreted off the cell.
Chain reaction
Nuclear energy
Explanation:
Question 1:
Chain reaction:
A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.
Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.
In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.
The energy needed to sustain the chain process is produced in the previous reaction.
Nuclear energy:
The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.
During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.
Nuclear energy is classified as a non-renewable source of energy.

It is the Archaea. The Archaea constitute an area and kingdom of single-celled microorganisms. These microorganisms are prokaryotes, which means they have no cell core or some other layer bound organelles in their cells.
Archaea are microorganisms that characterize the breaking points of life on Earth. They were initially found and depicted in extraordinary conditions, for example, aqueous vents and earthly hot springs. They were additionally found in a different scope of profoundly saline, acidic, and anaerobic conditions.
