Explanation:
Un estimulo es cualquier cambio que es capaz de producir una respuesta por parte del organismo. Los receptores son estructuras muy especializadas capaces de percibir los estímulos y convertirlos en impulsos nerviosos
Albedo is the "whiteness" of a surface. It is a reflection coefficient, and has a value of less than one. The albedo of a surface is the ratio of radiation reflected from the surface to the incident radiation. Hope this helps. Have a nice day. Feel free to ask more questions.
Answer:
A single gene form different isoforms of protein that result from the alternative splicing of pre-mRNA sequences. one gene many polypeptide hypothesis applies here very well. This whole process helps in proliferating informational diversity and functional capacity of a gene that'll ultimately he;p in gene regulation.
This alternative splicing of pre-mRNA also produces proteomic diversity that result in various development states as well as various disease conditions later.
Answer:
21 chromosomes
Explanation:
Meiosis is a type of cell division that produces 4 haploid daughter cells (i.e., gametes) from a single diploid cell. This parental cell undergo one (1) cycle of DNA replication and two (2) cell divisions, thereby, in the case of the Norway rats that have 42 chromosomes, the final number will be 21 (21 x 2= 42)
This is because of B. Their cells are in direct contact with the environment.
