The Centrosome is the organelle responsible for organizing the cell into two parts in preparation for cell division. It develops the spindle fibers used in cell division.
The solution is B.
<h3><em><u>C.</u></em><em><u> </u></em><em><u>This cell has no nucleus.</u></em></h3>
Because bacterial cell do not have a well-defined nuclear membrane. The coiled DNA particles lie naked in the cytoplasm. This is called nucleoid. While in animal cells the nucleus is surrounded by a well-defined nuclear membrane.
Answer;
A. brain's use of incoming signals to construct perceptions
Explanation;
Bottom-up processing involves processing information by starting with the individual elements of a visual stimulus and gradually building up a final representation and interpretation.
The evidence of bottom-down processing by Hubel and Wiesel showed that we have neurons that pick up specific elements of a visual stimulus and then they are assembled into a more complex form.
The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.
