Los componentes básicos del ADN son los nucleótidos, que se componen de tres partes: una desoxirribosa (azúcar de 5 carbonos), un grupo fosfato y una base nitrogenada (Figura 9.3). Hay cuatro tipos de bases nitrogenadas en el ADN.
The cells of the immune system can be categorized as lymphocytes (T-cells, B-cells and NK cells), neutrophils, and monocytes/macrophages. These are all types of white blood cells. The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins
Physics, there are three types of main muscles, skeletal muscle, cardiac muscle, and smooth muscle, but it's physics that makes all these muscles contract, thus movement. So it's Physics that plays a big role in muscle movements.
Answer:
- Oxygen
- The body cells
- Producing energy
Explanation:
We breathe in oxygen from the external environment. Oxygen passes into our lungs and is passed into the blood capilaries. Here it is carried to all the cells throughout the body.
It diffuses into the cells and is necessary for the final stages of energy production by aerobic respiration. Therefore, it is necessary for powering all cellular processes.
As plasma membrane is semipermeable membrane which allow materials to move across it in both direction. Semi permeable is the reason
