~~9. what are the haploid reproductive structures of fungi called? (1 point)
Katarina [22]
The correct answer is the spores. Fungi reproduce asexually by budding, fragmentation, or spore production. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte.

Define ovipary, ovovivipary, and vivipary. Which vertebrates use each type of reproductive strategy?
Irina-Kira [14]
Oviparity is a mode of reproduction in which young, developed in fertilized eggs, laid outside the mother's body. This mode of reproduction is found in most reptiles and all birds.
Viviparity means that their young develop inside the mother's body and are born alive. This is the mode of most mammals.
<span>Ovoviviparity is similar to viviparity in that there is internal fertilization and the young ones are born alive but differ in that there is no placental connection, the young are fed by egg yolk. This is found i</span><span>n </span><span>seahorses, for example.</span>

The bacterial transduction experiments done by Hershey and Chase, and the bacterial transformation experiments done by Griffith,
Katarina [22]

Answer:

Hershey Chase  and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.

Explanation:

Both experiments have was based on different phenomenon and techniques to prove same conclusion.

Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.

Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.
