Petri dishes. After allowing the bacteria to replicate for several generations, the scientist observes that some of the dishes now contain colonies with purple and red colored bacteria. What can be concluded from this observation?
A.
Asexual organisms will undergo genetic changes if placed in a Petri dish.
B.
Organisms undergo mutations to become better suited to their environment.
C.
Mutations lead to genetic variation in organisms that reproduce asexually.
D.
Genetic changes are always harmful to organisms that reproduce asexually.

Answer:

The correct answer is option B.

Explanation:

The ultraviolet light leads to a mutation in bacteria. It is a probability that UV light had an impact on a colony of blue-colored bacteria resulting in a mutation. The mutagen found in the ultraviolet light leads to a mutation in bacteria. It is known that mutation refers to a change in the genetic substance and can lead to more functionalities in a species.

What di eukaryotes most likely evolve from?
otez555 [7]

Answer:

Prokaryotes.

Explanation:

Most of the Eukaryotes most likely to evolve from the Prokaryotes.  Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside  the plasma membrane, which is a thin layer of lipid that completely surrounds the cell.  Prokaryotes reproduce by binary fission method.

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then,
Sveta_85 [38]

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynucleotide
mr Goodwill [35]

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.
