Answer:
C. It was covered in sediment.
Explanation:
Explanation:
The cell nucleus is a membrane-bound structure that contains a cell's hereditary information and controls its growth and reproduction. The main function of the cell nucleus is to control gene expression and mnedite the replication of DNA during the cell cycle.
by gene activation
ESCs divide into two cells: one is a duplicate stem cell (the process of self-renewal) and the other daughter cell is one which will differentiate. The daughter cells divides and after each division it becomes more specialized.
Answer:
it would not be able to transport water and nutrients as there are no xylem and phloem
Explanation:
Answer:
Distinctive characteristics of the cell membrane in the <em>Pseudomonas</em> genus:
- low outer membrane permeability
- protein channels for the uptake of nutrients
- porin proteins with cell adhesion and signaling functions
Explanation:
The plasma membrane is a lipid bilayer that separates the cytoplasm of the prokaryotic cell from the external environment. The cell membrane is selectively permeable in order to regulate the transport of substances (nutrients and cell waste products). <em>Pseudomonas</em> is a genus of Gram-negative bacteria that have a thin peptidoglycan layer and an outer membrane. In <em>Pseudomonas</em> species, the cell membrane contains porin proteins involved in the uptake of nutrients, such as, for example, OprB, OprB2 (glucose), OprG (phosphate) and OprH (pyrophosphate). Moreover, the cell membrane of these bacteria has low outer permeability, which confers a high resistance to antibiotics.
