Name the dark, linear, thread like structures that are in some of the onion root tip cells.  What molecule of heredity do they contain?

For smooth ER which macromolecule(s) ( carbohydrate, proteins, lipids, and Nucleic acids) contribute to the structure and function of this organelle. How does it contribute to the organelle function

* b. Briefly explain how the use of this molecule (CA1P) disrupts both stages of photosynthesis while the Rubisco enzyme is associated with only one stage. Codule 3: The principles of heredity 1. Let's take the example of the gray kangaroo (Macropus fuliginosus) whose ploidy is 8 and the sexual determinism of this species is carried out according to the XY mode. From a male kangaroo: a) Draw the karyotype of this individual, obtained by stopping division at metaphase. Your drawing should include: a. All maternal and paternal chromosomes involved (different colors) b. An example of autosome and heterochromosome c. An example of homologous chromosome, sister chromatid and centromere. d. The total number of chromosomes in a metaphase kangaroo cell. e. A sentence to explain the difference between the terms gene and allele that might apply to this species.
