The correct answer is option a. true.
The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.
The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.

In addition, in meiosis I, the chromosomal number is reduced from diploid (2n) to haploid (n) during this process. ... In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Los seres invertebrados y los vertebrados tienen más elementos en común de lo que se pensaba. Un estudio, con participación del Consejo Superior de Investigaciones Científicas (CSIC), prueba que existe gran similitud entre los sistemas excretores de ambos grupos de animales. Según la investigación, las células encargadas de filtrar la sangre en la formación de orina, alojadas en los riñones de vertebrados, son similares a las que realizan una función análoga en invertebrados.
