The correct option for this question is as follows:
a) they are made of many cells
b) they are made of one or more cells
c) they come from the same kind of cell
d) they come from noncellular structures
Answer:
The correct answer is - option b. they are made of one or more cells
Explanation:
The cell theory has three major parts that are; the cell is the basic and physiological unit of the organism, all living organisms are made up of one or more cells, new cells come from the pre-existing cells.
On the basis of the cell theory, we can say that all organisms including the cheetah that is a multicellular organism or paramecium a single-celled organism, are made up of one or more cells.
This is because the GP120 protein
of the HIV virus that forms the ‘knob’ is
essential for the infection of CD4 cells
of the immune system by the virus. The glycoprotein is, therefore, a good
target for vaccines especially since the
molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.
Proteins are polymers of amino acids. There are a fixed set of amino acids that are involved in the making of a protein. These amino acids are varied in number and type to give rise to different combinations in a polymer. This creates a diversity of protein molecules.
The amino acids link to other amino acid in the polymer through the formation of a peptide bond between them. It forms when the carboxylic group of one amino acid molecule reacts and binds to the amino group of the other molecule.
---C---- if brown snails are mostly eaten that most likely means they are more common. If less than snails are eaten then stripedsnails would eventually over populate brown snails and then brown snails would overpopulate striped snails ..... so elminate b and d and snails probably won't go extinct..... so I would have to go with c
