A??
The scientist collaborates with others to plan and carry out an experiment and then writes a paper that has a clear conclusion. He submits it to a professional journal for peer review, after which the results are presented publicly.
Answer: In addition to their role in producing ova, the ovaries also have the distinction of being an endocrine gland because they secrete hormones—primarily estrogen and progesterone—that are vital to normal reproductive development and fertility. The ovaries are oval shaped and about the size of a large grape.
Answer:
They showed how organic molecules could be made from Earth's early atmosphere.
Explanation:
Miller-Urey experiments were based on the ides of a-bio-genesis. It means the production of life through the non biological factors. In this experiment it shows that life can be produced through chemicals and molecules that were found in the early form of earth and is composition.
It kind of gives off to the evolution theory and the amino acids which are the building blocks of life and were given rise to during the simulation.
Answer and explanation:
Gram positive bacteria :
1) They retain crystal violet stain thus staining purple
2)They only produce exotoxins.
3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
La fiebre es la temperatura corporal anormalmente alta. Por lo general, se define como tres lecturas de temperatura oral superiores a 38 ºC o 100.4 ºF en un período de 24 horas, o una lectura de temperatura superior a 38.5 ºC o 101.3 ºF. La fiebre es la respuesta del cuerpo a una infección. Sin embargo, sólo en la mitad de todos los pacientes con cáncer que desarrollan fiebre es posible encontrar un origen claro de la infección.
La fiebre es particularmente preocupante si ocurre en un momento en que se sabe o se espera que el nivel de leucocitos sea bajo (en el nadir). Durante ese tiempo, las defensas normales del cuerpo contra las infecciones están bajas y es necesario evaluar la fiebre más detenidamente de inmediato.
A veces, la quimioterapia y la fiebre guardan relación, porque los pacientes que reciben tratamientos de quimioterapia y tratamiento biológico pueden tener fiebre como parte del "síndrome seudogripal". La fiebre asociada con el síndrome seudogripal usualmente alcanza los 40 ºC o 104 ºF y suele aumentar después de un escalofrío fuerte. Este comportamiento es similar al cuadro clínico que presenta una sepsis (una infección en la sangre), de manera que es importante que los pacientes que reciben tratamiento biológico conozcan la evolución habitual de la fiebre después del tratamiento.
