Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.

Explanation:

Each gram of protein contains 4 calories. Protein makes up about 15 percent of a person's body weight. Chemically, protein is composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur.

Canada is considered an economically developed country
Gnoma [55]
Canada's gross domestic product (GDP) expanded by 6.1% in the first quarter of the year – the highest rate of growth among developed nations – and the country is expected to lead Group Seven (G7) nations in economic growth for at least the next two years. The reasons are many: Canada's banking system is sound.

¿Que impacto tiene los diferentes tipos de centrales eléctricas en nuestro medio ambiente?​
Fofino [41]

Answer:

Sin los correspondientes controles y marcos regulatorios, las centrales eléctricas pueden tener efectos adversos sobre el medio ambiente y contaminar los ecosistemas naturales, representando un serio riesgo para la salud humana

Explanation:

Las centrales eléctricas representan un riesgo latente para el medio ambiente, con lo cual ellas deben estar bajo un estricto marco regulatorio y control por parte de las instituciones gubernamentales especializadas para tal fin. Por ejemplo, las centrales hidroeléctricas generan la inundación permanente de grandes áreas (incluso miles de hectáreas) con el objetivo de aumentar la capacidad de generación de energía eléctrica. Por otra parte, se cree que aproximadamente el 50% de la polución industrial se debe a la acción de centrales eléctricas convencionales, las cuales utilizan la combustión del carbón, el petróleo o el gas natural con el objetivo de generar energía eléctrica. Este tipo de centrales eléctricas producen dióxido de carbono (CO2), el principal gas de efecto invernadero y considerablemente deterioran la calidad del aire que respiramos mediante la liberación de partículas contaminantes, presentando efectos adversos tanto para la salud humana como para el medio ambiente. Finalmente, la instalación de centrales eléctricas a base de la energía nuclear no generan gases causantes del efecto invernadero, pero pueden representar un serio riesgo debido a la posibilidad de liberación de materiales radiactivos durante accidentes nucleares, los cuales son capaces de contaminar permanentemente el medio ambiente. En este punto, es importante aclarar que los riesgos de accidentes en centrales nucleares se ha reducido notablemente en las últimas décadas y, por lo tanto, este tipo de centrales eléctricas se consideran relativamente seguras.

) A field biologist finds an unfamiliar single-celled organism in a sample from the surface of a marshy area. What observations
liberstina [14]

Answer:

Genetic analysis, structure analysis and study the behaviour.

Explanation:

Genetic analysis, structure analysis and study the behaviour of organisms are the observations or tests that would make it possible to determine whether it is a protozoan, fungus, or algae because these analysis provides information about the genetic makeup and structure of their cell. If the cell wall is made of chitin then it is considered as fungi, if the cell wall is made of peptidoglycan then it is an algae and if the cell wall is not present then it is considered as animals like protist.
