According to the theory of endosymbiosis How did cells acquirenhow did cells acquire chloroplast
stira [4]

According to endosymbiotic theory, the chloroplast evolved as a result of engulfment and assimilation of a Cyanobacteria by an eukaryotic cell.

Explanation:

  • Endosymbiotic theory supports the view that ceratain organelles of the eukaryotic cell evolved as a result of engulfment of single celled organism.
  • Evidences  that support this theory is the presence of organellar DNA.
  • It is assumed that Mitochondria evolved as a result of engulfment and assimilation of an aerobic prokaryote while Chloroplast evolved due to engulfment and assimilation of a photosythetic prokaryote by an Eukaryote.
  • After the engulfment ,these organisms however escaped the phagocytosis and began to benefit the eukaryotic Host.
  • Soon it lost many of its Genes to the eukaryotic nucleus and became dependent on the Host.
  • Thus a symbiotic association was established between the prokaryote and the host.Giving rise to cell organelles.

If you cross two organisms that are heterozygous for a trait, what percent of
brilliants [131]

Answer:

25%

Explanation:

Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
