lilavasa [31]

Answer:

The correct answer is- photosynthesis

Explanation:

According to the endosymbiotic theory, an ancestral cell engulfed a cyanobacteria and lived in symbiotic association with that bacteria and over time this bacteria evolved into the chloroplast and the ancestral cell developed into plant cell.

So as cyanobacteria was the first aerobic cell that can evolve oxygen and can do photosynthesis to produce organic food so it could be concluded that the presence of endosymbiotic cyanobacteria provided a cell with the advantage of photosynthesis.

aleksandr82 [10.1K]

Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

<h3>WHAT IS MEIOSIS?</h3>

Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.

Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.

Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.

Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.

Nookie1986 [14]

Answer:

A stem and leaf diagram has two parts, the 'stem' and the 'leaf'. In the stem, there are numbers in ascending order from top to bottom. In the leaf, there are numbers showing the next digit of the number in the stem. The leaf is to the right of the stem.

The function of a stem and leaf diagram is to summarize data in a way that separates numbers into different number categories.
