launchpad A Drosophila mutation called singed (s) causes the bristles to be bent and misshapen. A mutation called purple (p) cau

ses the fly’s eyes to be purple in color instead of the normal red. Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes. The F1 were intercrossed to produce the F2, and the following results were obtained. What are the genotypes of the parental flies in Cross 1

Answer:

ppss and PPSS

Explanation:

Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.

And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.

A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.

Thus, the genotypes of the parental flies in Cross 1 are

PPSS and ppss

What is bacteria flagellum? What is made of and its function? What type of organization can flagella have on cells?
Nadusha1986 [10]

Answer:

Bacterial flagella is the external structure that is thin, long and filamentous. It is attached to the cell wall of the bacteria which helps in the locomotion of the bacteria. It has three parts a filament, hook and basal body. The basal body is incorporated in the cell membrane.

A flagellum is made up of a protein called flagellin. It is a rigid protein and helps in making the hollow core of the filament by assembling together to form a structure which is cylindrical in shape.

The organization of flagella on bacterial cells is helpful in the identification of bacterial species. Mostly 4 type of organization of flagella is present on bacterial cell that are monotrichous, amphitrichous, lophoyrichous and perithrichous.

In monotrichious bacteria, only one flagella is present on one side, in amphitrichous both side of the cell have an equal amount of flagella. Lophotrichous bacteria have a group of flagella at one side of the cell and amphitrichous bacteria have many flagella distributed equally on its cell.

yuradex [85]

All of the following are forms of energy a living organism can use except nuclear energy. Nuclear energy is the use of nuclear reactions that release nuclear energy to generate heat ( thermal energy is being transferred between two objects).Exposure to any radioactive material and energy  is bad because the nuclear energy damages human body and cells.
