Black_prince [1.1K]

The order in which the earliest organisms evolved -

  • Archaea and bacteria
  • Protists
  • Fungi and shell-less invertebrates
  • Green algae
  • Shelled Invertebrates

On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:

  • Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
  • The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
  • Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
  • Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
  • Shelled Invertebrates are the youngest organisms that evolved recently among these.

Thus, the correct order is -

  • Archaea and bacteria
  • Protists
  • Fungi and shell-less invertebrates
  • Green algae
  • Shelled Invertebrates

In a sample of double stranded dna if 19% of the nitrogenous bases are guanine what percent of the nitrogenous bases are adenine
Georgia [21]

Answer:

31%

Explanation:

Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If

G = 19% then C= 19%

19% + 19% = 38%

100% - 38% = 62%

62% for A and T

Divide by 2 and you get

31%
