Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
Answer:
To make ATP
Explanation:
It is the main because it occurs in both aerobic ( presence of oxygen ) and anaerobic respiration ( absence of oxygen ).
The carbon cycles recycles caronatoms(carbon dioxide) and the nitrogen cycle recycles nitrogen.and the carbon cycle makes carbon dioxide and the carbon dioxide goes to the trees ,and the trees get the nitrogen and starts the cycle again.
Answer:
La respuesta correcta es "a. arterias, b. venas; y c. capilares".
Explanation:
Los vasos sanguíneos son una serie de conductos a través de los cuales el cuerpo transporta la sangre, asegurando que todas las células del cuerpo tenga acceso a oxígeno, elemento necesario para la respiración celular. Hay tres tipos de vasos sanguíneos: arterias, venas y capilares. Las arterias llevan la sangre del corazón a los órganos, las venas transportan la sangre de los órganos al corazón y los capilares son vasos muy pequeñitos que llegan a las partes más pequeñas del cuerpo.
