Bacteriophages most frequently have which sort of morphology, when bacterial genes are transmitted from one bacterium to another by a virus.
<h3>What does a bacteriophage look like morphologically?</h3>
The best method for examining the morphology of bacteriophages is electron microscopy. It has a polyhedral head, a short neck and collar, and a straight tail. It is tadpole-shaped. The head is 950 x 650 in size and has a bipyramidal hexagonal form. A membrane (capsid) that is about 35 thick encloses the contents of the head.
<h3>What kind of bacteriophage is most typical?</h3>
Assphages are a large and common family of tailed bacteriophages that are thought to infect bacteria belonging to the phylum Bacteroidales. Members of this viral family have never been isolated in culture and are still poorly understood despite being present in up to 50% of people and accounting for up to 90% of human gut viromes.

Answer:
I believe that the answer is c.
Explanation:
car·ti·lage
/ˈkärdlij/
noun
firm, whitish, flexible connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It is more widespread in the infant skeleton, being replaced by bone during growth.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.
Answer:
A. Yes, because the %A approximately equals the %T and the %G approximately equals the %C in both species.
Explanation:
According to Chargaff's rule, in all cellular DNAs, the number of adenosine residues (A) is equal to the number of thymidine residues (T). And the number of guanosine residues (G) is equal to the number of cytidine residues (C). Therefore, the sum of the purine residues equals the sum of the pyrimidine residues (A+ G= C+ T). It is based on the fact that a purine base always pairs with a pyrimidine base in a double helix DNA.
Chargaff’s rule is followed in all the double-helical DNA molecules irrespective of the species. In DNAs of sea urchin and salmon, the percentage of adenine is equal to that of the thymine and the percentage of guanine is equal to that of the cytosine. Therefore, Chargaff's rule is followed.
