PROTO-ONCOGENES are corresponding normal cellular genes to an oncogene that is responsible for normal cell growth and division.
An oncogene refers to a gene that is capable of causing cancer due to damage to the DNA molecule either by virus or other DNA damaging agents. A proto oncogene is the normal version of the gene while an oncogene is the abnormal version of the concerned gene.
Answer:
18ft
Explanation:
because there are 18 blocks total 9 blocks at the bottom 6 in the middle and 3 at the top.
The answer is; epididymis
Spermatogenesis (formation of immature sperm cells) occurs in the Sertoli cells located in the seminiferous tubules within the testes. The produced immature sperm cells migrate to the epididymis where they are stored as they mature to viable sperm.
Edmond Locard founded the first police crime laboratory in 1910 in Lyon, France. It is impossible for criminals to flee a crime scene without leaving behind traces of evidence that can be used to identify them, according to Locard's "exchange principle."
- This concept served as the foundation for the forensic sciences, a body of methods for collecting and analyzing physical evidence from crime scenes. The "Sherlock Holmes of France," French criminologist Edmond Locard, who founded forensic science, lived from 13 December 1877 to 4 May 1966. Every encounter leaves a trace, according to his formulation of the fundamental tenet of forensic science.
- In the field of research that examines fingerprints, and dactylography, Locard made significant contributions that are well known.
- Although Edmond Locard passed away in 1966, his exchange principle has had a significant impact on forensic science and is still widely cited today.

Answer:
The leafhoppers eat plant tissues and, at the same time, they are eaten by spiders that are the food of large lizards. Finally, these lizards are the food of birds that are eaten by snakes.
Explanation:
The food chain starts with primary producers such as plants and algae (i.e., level 1), then goes through herbivorous species including insects and fish (level 2) and finally ends with carnivores such as rodents, snakes and hedgehogs (levels 3, 4 and sometimes 5, which depends on presence of larger predators). Thus, the trophic levels are represented by the number of steps of the food chain. In an ecosystem, the organisms can also be classified according to the mode of obtaining the food in producers (autotrophs), consumers (heterotrophs) and reducers (detritivores).
