The right answer is A codon sequence is incorrect.

Biologists have compared the corresponding DNA and RNA sequences in B cells (white blood cells), the material being provided by various ongoing sequencing projects. They identified more than 10,000 sites where the two molecules differ, with about 40 percent of the genes having at least one transcription error. This error can be found at the level of the codons of the amino acids, which implies a change of one amino acid by another.

Serggg [28]

The process that transports solutes, including many drugs, into the tubular fluid is called tubular secretion. Under this process, there is transfer of materials from peritubular capillaries to the renal tubular lumen and the secretion is caused mainly by active transport and passive diffusion.

lions [1.4K]

Answer:

  • Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
  • Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups.  The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

  • Algaes are autotroph
  • Protozoans are heterotroph

<u>Protozoans</u>:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.  

<u>Algae</u>:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.

Why is important for scientists to remain open minded about information they come across in their experiments
Lina20 [59]
It is important for scientists to remain open minded about information that they come across in their experiments, so that they do not become biased about the result. it can always happen that the results that come out are contrary to what the scientist expected. It is important to openly accept that the scientists prediction was wrong.
