1. Con la finalidad de contar con un alimento para animales con un valor nutritivo más alto que el maíz común, un grupo de expertos comparan dos nuevas variedades de maíz con un contenido de aminoácidos modificado llamadas opaca-2 y harinoso-2, con maíz común. Los investigadores mezclan maíz y soya para alimentar animales, con 12%, 16% y un 20% de proteína. Suministran diariamente este alimento compuesto a 10 pollos machos y anotan su aumento de peso al cabo de 21 días. El aumento de peso de los pollos es una medida de valor nutritivo del contenido del alimento, que se suministra. De acuerdo a lo anterior identifica ¿Cuál es la variable dependiente? ¿Cuál es la variable independiente?, y el aumento de peso ¿qué sería?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
