The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Bogdan [553]

Answer:

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

Explanation

Energy can be calculated by the equation

Q = m x Cp x delta T

where

m = mass = 0.5 kg

Cp = specific heat of water = 4184 J

Delta T = 12 degrees

Multiplying all

Q = 0.5 x 4184 x 12 = 25104 Joules

Converting it to Calories

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

During the 18th century what was England’s view on inoculations
stepan [7]

Answer:

For many centuries, smallpox devastated mankind. In modern times we do not have to worry about it thanks to the remarkable work of Edward Jenner and later developments from his endeavors. With the rapid pace of vaccine development in recent decades, the historic origins of immunization are often forgotten. Unfortunately, since the attack on the World Trade Center on September 11, 2001, the threat of biological warfare and bioterrorism has reemerged. Smallpox has been identified as a possible agent of bioterrorism (1). It seems prudent to review the history of a disease known to few people in the 21st century.

Edward Jenner  is well known around the world for his innovative contribution to immunization and the ultimate eradication of smallpox (2). Jenner's work is widely regarded as the foundation of immunology—despite the fact that he was neither the first to suggest that infection with cowpox conferred specific immunity to smallpox nor the first to attempt cowpox inoculation for this purpose.

En el hombre el color negro de los ojos “A” domina sobre el color azul “a” Una pareja en la que el hombre tiene los ojos negros
umka21 [38]

Las respuestas a estas preguntas son:

a) Genotipo del padre Aa (ojos negros)

b) Cruzamiento: Aa (padre) x aa (madre)

c) Frecuencias genotípicas esperadas: 1/2 Aa; 1/2 aa  

En genética, dominancia completa se refiere al proceso  de herencia en la cual un individuo heterocigota, es decir, el individuo que presenta dos alelos diferentes para el mismo gen, presenta el mismo fenotipo que un individuo homo-cigota para el alelo dominante (el alelo dominante es aquel que enmascara la expresión del alelo recesivo en individuos heterocigotas).

En este caso, el carácter 'color de ojos' presenta un patrón de herencia monogénica, donde el alelo 'A' dominante codifica para el rasgo fenotípico ojos negros, mientras que el alelo 'a' recesivo codifica para el rasgo fenotípico ojos azules.  

En el ejemplo, la pareja tuvo progenie en la cual uno de los hijos presenta el rasgo recesivo ojos claros, con lo cual el padre debe ser heterocigota y poseer un alelo recesivo 'a'; mientras que la madre expresa el fenotipo recesivo y por lo tanto su genotipo es 'aa'. En consecuencia, el cruzamiento de un padre heterozigota 'Aa' con una madre homo-cigota recesivo 'aa' producirá una descendencia con una frecuencia genotípica esperada de 1/2 (50%) de hijos con ojos 'color negro' de genotipo Aa y 1/2 (50%) de hijos con ojos 'color celelste' de genotipo aa >>

Cruzamiento: Aa (padre) x aa (madre)

Gametos padre: 1/2 A; 1/2 a

Gametos madre: 100% a

Cuadro de Punett (combinaciones gaméticas):

                  A           a

a               Aa          aa

a               Aa          aa

En consecuencia,  este cruzamiento producirá 50% individuos ojos color negro (genotipo Aa) y 50% individuos con ojos color celelste (genotipo aa)

Heterotrophs obtain their food from other sources. Autotrophs produce their own food. with this in mind. What are protozoans?
Ilia_Sergeevich [38]

Protozoans are free-living or parasitic eukaryotic organisms. They feed on dead and decay matter.

<h3>What are protozoans?</h3>

Protozoans are microorganisms. They are eukaryotic organisms, and they can be parasitic or free-living. They feed on dead and decay matter. Examples are amoeba, euglena, paramecium, etc.

Organisms that eat dead or decay matter are called decomposers. They clean the environment by eating the debris or decay, matter. Microorganisms like bacteria or protozoans are decomposers.

Thus, protozoans are decomposers as they feed on dead and decay matter.

To learn more about protozoans, refer to the link:
