Answer: Las células son las unidades de construcción más básicas de la vida. Todos los seres vivos están compuestos por células.
Explanation:
Answer:
metal
Explanation:
Metals have unique characteristics that differ from other substances: they are solid, do not let light (they are opaque) and conduct electricity and heat well, having a special shine called metallic. When heated they are malleable and can be molded into various shapes, from wires to plates and bars. For these reasons, we can say that a malleable and ductile material - or capable of being hammered into different shapes without breaking and being pulled by a wire - is probably a metal.
Answer:
Differential and selective
Explanation:
A selective media is one used for growth of only selected microorganisms. Since this medium is using methylene blue to inhibit gram-positive bacteria and allowing the growth of gram-negative, then we can cathegorize it as selective. Selective growth media is also used in cell culture to ensure the survival or proliferation of cells with certain properties, such as antibiotic resistance or the ability to synthesize a certain metabolite, so the researchers can study or farm said metabolite or an specific reaction to an antibiotic.
Meanwhile, a differential media, also called indicator media, distinguish one microorganism type from another on the same media. This is done through biochemical characteristics which reacts to specific nutrients or indicators (neutral red, phenol red, eosin y, or methylene blue) added to the medium to visibly indicate the defining characteristics of a microorganism. Since this media is changing colors when the acidic concentration increases, it is a differential media as well.
Energy cannot endlessly cycle through living systems, because energy is ONLY PARTIALLY transferred.
