Explanation:
When a person opens the door, he or she uses 3 systems:
1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.
2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.
3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.
we can conclude that the correct answer is:
Answer:
1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.
2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.
3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.
Answer:
Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.
Explanation:
The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.
The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.
Thus, the correct answer is option (d).
Answer:
MHCI
Explanation:
Major histocompatibility complex I (MHCI) is present on the nucleated cells of the body. Endogenous pathway represents the pathway of MHC class I molecules.
MHCI display peptide fragment of proteins to the cytotoxic T cells with the help of CD8 ( Cluster of differentiation). CD8 binds with the MHCI and expressed on the surface of cytotoxic T cells.
Thus, the correct answer is option (D).
The raw materials of H2O and CO2 are located there
