The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.
- Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.
- Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information.
- Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.
- Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine.
- The muscles become overstimulated as a result, which will cause paralysis and death.

Answer:
Cats also purr when they are nervous or in pain, leading some experts to believe that this uniquely feline vocalization is actually a method of self-healing. A domestic cat's purr has a frequency of between 25 and 150 Hertz, which happens to be the frequency at which muscles and bones best grow and repair themselves.

Answer:
plate: a disk formed in the phragmoplast of a dividing plant cell that eventually forms the middle lamella of the wall between the daughter cells.
plate boundary: Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. ... Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other
earthquake: An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. The strain becomes so great that rocks give way by breaking and sliding along fault planes.
convirgent: In evolutionary biology, convergence pertains to an evolutionary process wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated.

Red blood cells transport oxygen throughout the body platelets aid in blood clotting and white blood cells help destroy and remove old cells and foreign substances. This is an example of how cells origin from the same cell (hematopoietic cell in the bone marrow) and then differentiate.
Hematopoietic stem cells are blood-forming stem cells. During hematopoiesis the hematopoietic stem cell divides via mitosis. As a result of mitosis, one daughter cell remains in the bone marrow to continue renewing the hematopoietic stem cells pool while the other goes through next stages of development. Maturate blood cell (red, white or platelet) to leave the bone marrow and enters the circulation.
