Which statement is most likely to apply to a cell that has DNA within its cytoplasm?

Which characteristic do euglenoids and algae share

Svetradugi [14.3K]

Euglenoids are unicellular protists commonly found in fresh water.They don not have a cell wall, despite that, a protein rich cell membrane called pellicle is present in Euglenoids.
Whereas,Algae are eukaryotic organisms comprising of no roots, stems, or leaves but they filled with chlorophyll and other pigments to carry out the process of photosynthesis. Similar to Euglenoids, they occur most frequently in water, specifically in plankton.
Hence,
Euglenoids and algae share a common characteristic,that is both are autotrophs. They produce complex organic compounds from simple substances present in their surroundings, by the use of energy from sun-light or inorganic chemical reactions.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children

vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

║ A ║O

O║AO║OO

There is a 50% of probability of having O offsprings with AO and OO.

║ A ║A

O║AO║AO

O║AO║AO

With AA and OO, the probability is 0%

║ A ║O

A║AA║AO

O║AO║OO

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.

Answer:

Bacteriophages (phages) are viruses that infect only bacteria and do not infect mammalian or plant cells. Phages are ubiquitous in the environment. Phages or bacteriophages were chosen as a model system for their simplicity, as they only contained protein-coated nucleic acid. Alfred D. Hershey and Martha Chase (who were part of the bacteriophage group) in 1952 studying the infection of the bacterium Escherichia coli by the T2 phage show that the information definitely resides in the DNA. They used phage with either [32P] -labeled DNA or [35S] -labeled proteins to infect the bacteria. Immediately afterwards, they centrifuged the sample so that the infected bacteria remain in the pellet and the virus capsids (proteins) remain in the supernatant. [35S] is found in the supernatant, whereas [32P] is found in bacteria. After one cycle of infection, it was observed that when phage labeled in the [35S] proteins were used, only 1% of the radioactivity was incorporated into the progeny. But when phages were [32P] labeled, more than 30% of the radioactivity was in the progeny. They showed directly that what is transmitted from one progeny to another is the DNA and not the proteins, despite having first "diluted" in a bacterium.

Explanation:

Bacteriophages are viruses that infect bacteria in a specific way. Bacteriophages, like other known viruses, are found in an intermediate zone between living organisms and inert matter. Bacteriophages bind to the host pathogenic bacterium, introduce their genetic material, replicate inside it and destroy it. Hersey, along with his assistant Martha Chase, used phages because they knew that T2 phages were made up of 50% proteins and 50% nucleic acids and that phages entered bacteria and reproduced. As the progeny carried the same infection traits, the genetic material of this had to be transmitted to the offspring, but the mechanism was unknown. These scientists carried out an experimental work with the T2 virus, a bacteriophage that infects the bacterium Escherichia coli, which it reproduces by attaching itself to the outer wall of the bacterium, injecting its DNA into it where it replicates and directs the synthesis of the phage's own proteins. Phage DNA is encapsulated within proteins and produces phages, which lyse or disrupt the cell and release phage from progeny. They infected a culture of bacteria with radioactively labeled phages: the protein coat with sulfur (35S) and its DNA with phosphorus (32P). After infection, they separated the phages from the bacteria by violent shaking using a mixer (hence the name of the experiment). By centrifugation the much smaller phages remained in the supernatant and the much larger bacteria in the pellet. 85% of the radioactivity corresponding to DNA appeared in the pellet and 82% of the protein in the supernatant. This result supported the idea that DNA was the only component of the bacteriophage that penetrated the interior of the bacteria and, having the ability to form new phages, constituted the genetic material.
