Answer:
The process shown in the model requires energy from the cell.
Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
Answer:
The activation of DNA synthesis may result from the stimulatory activity of one or more cytoplasmic factors and In fusions of cells in G2 and S, however, nuclei continue their previous activities,
Explanation:
Answer;
-Central nervous system
Explanation;
-The nervous system consists of two main parts: the central nervous system and the peripheral nervous system: The central nervous system is made up of the brain and spinal cord.
-The central nervous system controls most functions of the body and mind.It controls all parts of the body. It receives and interprets messages from all parts of the body and sends out instructions. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
-The spinal cord serves as a conduit for signals between the brain and the rest of the body and also controls simple musculoskeletal reflexes without input from the brain.
Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.
Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.
An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.
