Answer:
White blood cells can be called the strong defender of our body from foreign substances. These cells are responsible for increasing the immunity power of a person.
Explanation:
Monocytes cells are also called white blood cells. These cells play a role an antigen that fight with outer danger and protect other white blood cells as well and prepare other cells to reduce the dead blood cells and renovate new blood cells.
These cells prevent cancer cells and fight against foreign antigens or particles. The Monocytes are the cells that develop in the bone marrow of a person and develop red blood cells.
In white blood cells, some macrophages cells are called the scavengers in the bone marrow that eat foreign particles and increase the immunity power of the person. The diagnose can be done with the help of blood testing.
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.
Solution
Cut open an onion.
Use forceps to peel a thin layer of epidermis from the inside.
Lay the layer of epidermis on a microscope slide.
Add a drop of iodine solution to the layer.
Carefully place a coverslip over the layer.
Observe it under a microscope to see onion cells.
Answer:
Kinase-connected receptors or receptor tyro-sine kinases react for the most part to protein and chemical go between. A solitary trans membrane helix interfaces the extracellular restricting area to the intra-cellular space. e.g. insulin, development factors. The official of the ligand triggers the commencement of a few succession of occasions related with phosphorylation of proteins, this is called protein kinase course.
For instance, the official of development hormone to the receptor in the plasma layer causes dimerization (by the actuation of Janus kinase 2, JAK2) of the receptor (conformation change) that bring about auto-phosphorylation of tyro-sine buildups. The official of SH2-space (src homology) protein (Grb-2) to the phosphorylated tyro-sine buildups invigorates cell development through a course of protein phosphorylation.
a). RTKs are the trans-membrane receptors, which have a ligand restricting site on the extracellular area and tyro-sine authoritative on the intra-cellular space. In the event that it comes up short on the extracellular area, the ligand can't tie to the receptor site, so no cell reaction happens.
b). On the off chance that it does not have the intra-cellular space, the ligand can tie to the receptor site, the receptor can't impart signs tot eh intra-cellular area because of the absence of intra-cellular space.
So children<span> look like combinations of </span>their parents<span> because they are. Each </span>parent<span>gives half of </span>their<span> genetic material to </span>their children<span>. The combination makes a unique combination of </span>their parents<span> genes. The scientific study of how </span>traits<span> are passed from </span>parents<span> to </span>children<span> is called genetics.
