Answer:
1. Mitosis c) The process of cell reproduction of human tissues that occurs when the cell divides into two identical cells
2. Nucleus a) The dense, active protoplasm found in the center of the cell
3. Cytoplasm b) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair
4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Explanation:
- Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.
- The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.
- The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions.
- The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.
A motor converts electrical energy into mechanical energy. Think of a car, it burns fuel (electrical energy) and turns it into tire spinning (mechanical energy)
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
Answer:
Vision
Explanation:
Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.
Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative in response to the stimuli.
Thus, the correct answer is option (d).
D- The digestive system breaks down your food and your circulatory system takes it throughout your body
