The pathogen must be isolated from the second organism and must be the exact same as the original pathogen.
Answer:
The <u>endocrine</u> system is a complex network of glands that release tiny amounts of hormones into the bloodstreams of humans and other vertebrate animals.
Explanation:
The endocrine system is a set of organs, tissues and cells whose function is to release various chemical substances called hormones into the bloodstream. The endocrine glands are the group of cells that produce and release hormones, which are secreted into the blood while waiting for the proteins that are designed to specifically capture each of them, are responsible for transporting them to the cells of the tissues and organs to which they must reach. Once there, they transmit the precise orders to regulate cellular activity.
Answer:
una alimentación saludable y la práctica de ejercicios físicos contribuyen al normal funcionamiento de la tiroides y mejoran el estado de ánimo
Explanation:
La tiroides es una glándula cuya función es secretar hormonas tiroideas tales como tiroxina y triyodetironina, las cuales están implicadas en el crecimiento y el control del metabolismo. Es bien conocido que problemas de salud tales como hipotiroidismo (hormonas tiroideas a concentraciones muy bajas) o hipertiroidismo (hormonas tiroideas a concentraciones excesivamente altas) afectan el estado de ánimo, y llevan a cuadros de estrés emocional como ansiedad y depresión. Una alimentación balanceada basada en alimentos ricos en yodo (pescados del mar, huevos, camarones) y zinc (maní, carne, semillas de calabaza, almendras), como así también el ejercicio físico regular, pueden producir el restablecimiento de los niveles normales de tiroxina y triyodotironina en personas con hipotiroidismo, lo cual ha sido asociado con una mejora inmediata en el estado de ánimo.
Answer:
No short answer.
Explanation:
First and second generation pesticides differ vastly in terms of their contents and effects.
First generation pesticides were used in early 20th century up until the 1940's and they consisted chemicals such as mercury and lead which were not biodegradable and they started adding up in the soil until it was not fertile anymore. Second generation pesticides were divided into three groups as chlorinated hydrocarbon, organophosphates or carbamates and consisted of chemicals that were less harmful for the soil and did not accumulate over time. Some examples to second generation pesticides can be DDT or dimethoate.
Broad spectrum and narrow spectrum pesticides have the difference of effective range between them. Narrow spectrum pesticides are designed to target a specific organism such as a specific plant or an insect whereas broad spectrum pesticides are applicable to a wider range of organisms and still have the same effect for each.
Chitin Inhibitors can be given as an example of narrow-spectrum pesticides and the second generation pesticides in the answer can be given as an example of broad-spectrum pesticides.

Allele frequency is determined by looking at the dominant and recessive allele of a genotype.
Using the given, we can come up with the following computation for the allele frequency:
allele A = 100/300 allele B = 50/300 allele O = 150/300
Hence, the frequency of allele A is 0.33 or 33%, allele B is .17 or 17% and allele O is 0.50 or 50%.
