Tropism
It is a biological phenomenon, indicating growth or turning movement of a biological organism. This is usually a plant in response to the environmental stimulus. This response is dependent on the direction of the stimulus. The stimulus must be perceived first, followed by movement towards or away to the stimulus. There are various types of tropism which are chemotropism, exotropism, geotropism and electrotropism.
Answer:
Cytokinesis divides the two cells into four daughter cells.
Explanation:
Meiosis is a type of cell division in which a single cell is divided into four daughter cells. These daughter cells are haploid i. e. half number of chromosomes. This type of cell division occurs only in sex cells of male and female organisms. There are two phases of meiosis. In meiosis 1, a single cell is divided into two daughter cells while in meiosis 2, these two daughter cells again divided into four daughter cells.
B. Convection
The heat causes the ocean water movement to continuously circulate around the globe
Answer:
C. Testes
Explanation:
Testes are only seen in males. It is an organ that produces spermatozoa (male reproductive cells).
Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Explanation:
passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.
