Explanation:
The right option is; d. consumers
All animals are consumers
Consumers are organisms that usually feed on other organisms or organic matter in order to gain energy because of their inability to manufacture their food from inorganic sources. All animals are consumers and they are also known as heterotrophs. There are different types of consumers. They include; primary consumers (herbivores e.g. goats, cows), secondary consumers (carnivores e.g. wolves, crocodile), and tertiary consumers (large carnivores e.g. eagle, lion)
The most common felsic rock is granite. Common felsic minerals include quartz,muscovite<span>, </span>orthoclase<span>, and the </span>sodium<span>-rich </span>plagioclase feldspars<span>. In terms of chemistry, felsic minerals and rocks are at the other end of the elemental spectrum from the mafic minerals and rocks.</span>

Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.

Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating deoxythymidine monophosphate (dTMP), which then undergoes phosphorylation to deoxythymidine diphosphate (dTDP), then to Deoxythymidine triphosphate (dTTP), and incorporated into DNA by the DNA polymerase (DNA pol). Thymine in tRNA arises post-transcriptionally, by S-adenosylmethionine-dependent methylation of a uridine 5'-monophosphate (UMP) residue in RNA.
Explanation:
Thymidylate synthase is an enzyme involved in <em>de novo</em> DNA synthesis. This enzyme (thymidylate synthase) catalyzes the transfer of the one-carbon group from 5,10-methylene-tetrahydrofolate (5,10-CH2-THF) to deoxyuridine monophosphate (dUMP) and subsequent methylation to produce deoxythymidine monophosphate (dTMP), which is then phosphorylated to deoxythymidine triphosphate (dTTP) by kinases and incorporated into DNA. On the other hand, specific tRNA methylases catalyze the methylation of transference RNA (tRNA) by using S-adenosylmethionine as a methyl donor. Since tRNA methylation is a post-transcriptional modification, this chemical reaction is considered an epitranscriptomic modification on the RNA molecule.
