1. Light energy excites electrons in the photosystems of the chloroplasts. These photosystems are located on the thylakoid membranes of the chloroplasts.

2. Water molecules are oxidized at photosystem 2, inside the lumen, located on the interior side the thylakoid membrane of the chloroplasts.

3. NADPH is formed at the NADP+ reductase at the stroma, located on the exterior side of the thylakoid membrane of the chloroplasts.

Which phase of mitosis is shown in the diagram
Lorico [155]

If there's this picture in the question, the right answer is metaphase.

A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.

Que signifie ADN et comment on le prouve?
irakobra [83]

Answer:

<h3>Qu'est-ce que l'ADN ?</h3>

L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.

Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".

Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

J'espère t'avoir aidé, bonnes études !
