Answer:
The correct answer would be c. The cell has a greater level of structural support.
Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.
They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.
- Lipid bilayer gives the rigidity or shape to the cell.
- It isolates the cell from the sorroundings.
- It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
- Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.
Hence, most appropriate choice would be c. The cell has a greater level of structural support.
Answer:
The correct answer is D.
Explanation:
The Amoeba Proteus example given in the question describing its engulfing smallar organism and digesting them is an example of a proces named "Phagocytosis". These cells are called phagocytes and the process can be used for both feeding purposes or defensive purposes by various cells. I hope this answer helps.

Yes, Genetically Modified Organisms (GMOs) should be used to help meet the world’s food needs but with taking care of all the ethical concerns.
<h3>What are genetically modified organisms</h3>
Organisms whose genetic material i.e. genes are being modified by certain molecular biology techniques are known as genetically modified organisms. The genes which are manipulated or modified are known as transgenes therefore these organisms are also known as transgenic organisms.
<h3>Why should they be used to help meet the world’s food needs?</h3>
As the world’s population is rapidly increasing, there is a need for new technologies which can help meet this challenge. Currently, the agriculture which is practiced today is not sustainable, a lot of herbicides and pesticides are being used which has led to massive destruction of the lands.
So, genetically modified organisms become a solution to it.
