Text SolutionText solutionverified iconVerified

(c) Tonoplast In plant cell the vacuole in bound by a single membrane called tonoplast. The tonoplast facilitates the transport of ions and other material against the concentration gradient into the vacuole. Hence, their concentration is higher in the vacuole than in the cytoplasm.
The outer membrane of mitochondria is formed of porin proteins and inner membrane bounds of chloroplast the stroma
The cell membrane of the plant cell is not a tonoplast. It is simple biological/unit membrane present in every cellular organism.

Consider a patient with typical pneumonia. Typical pneumonia is when the alveolar sac is full of some fluid, usually produced by bacteria in the form of "pus." What causes the patient to have problems with breathing? Remember to phrase your answers with correct anatomy and physiology. When responding to another classmate, explain what is happening to the ventilation chart of the patient. Does tidal volume change? Does inspiratory volume change? Does expiratory volume change? Does total lung volume change? Does respiratory reserve volume change?

(5 points) The most recessive, X-linked trait of white eye color has been extensively used in Drosophila (fly) genetics research. Purple and red eye colors are also possible in flies. A red-eyed female is crossed with a purebred white-eyed male. All offspring in the F1 generation have purple or red eyes.
  1. Write each of the parents' genotypes of their sex chromosomes using the standard formatting for X-linked genes.
  2. Given the offspring in F1, what is the dominance series for fly eye color?
  3. Draw a Punnett square for the P to F1 generation and note the ratios of each offspring regarding sex and eye color.
  4. Given the table below, how well do the proposed parent genotypes match the actual F1 offspring born?
