Embryos are an evolutionary adaption of

Biology
1 answer:
lara [203]3 years ago
4 0

El estudio comparado del desarrollo de los embriones aportaría, según el Darwinismo, otra de las pruebas clásicas en favor de la evolución. Al parecer, determinadas similitudes entre embriones de peces, aves, mamíferos y seres humanos demostrarían que todos ellos descenderían de antepasados comunes parecidos a los peces. <span>Darwin </span>lo explicaba así:

"De dos o más grupos de animales, aunque difieran mucho entre sí por su conformación y costumbres en el estado de adultos, por las fases de embrionarias muy semejantes, pueden estar seguros de que todos ellos son descienden de una misma forma madre y, por que tienen estrecho parentesco. Así, pues, la comunidad de la estructura embrionaria revela la comunidad de origen; [...] La embriología aumenta mucho el interés cuando se considera el embrión como un retrato, más o menos borroso, el progenitor de todos los miembros de una sola gran clase "

Transposable elements make up 44% of the human genome. What is thought to be their function?
AfilCa [17]

Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.

Explanation:

Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.

The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.

Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.

In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.

Photosynthesis occurs in both prokaryotes and eukaryotes. How do the locations where photosynthesis occurs differ in prokaryotes
mamaluj [8]

Answer/Explanation:

In eukaryotes, photosynthesis occurs mainly in green plants. These organisms have specialized organelles called chloroplasts that carry out photosynthesis. These contain photoreceptors that absorb photons from the sun through a pigment called chlorophyll, providing the energy to synthesise glucose from carbon dioxide and water.

In contrast, prokaryotes that carry out photosynthesis are able to do so because they have folds in the plasma membrane that permit the attachment of chlorophyll. They do not have specialized membrane-bound organelles like eukaryotes.
