Stars are classified based on the spectral type (i.e. a means to measure the photospheric temperature and density by getting information about the ionisation state).

Under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type) (Harvard Spectral classification based on the surface temperature of the stars). A luminosity class is added to the spectral class using Roman numerals (Yerkes Spectral classification). This is based on the width of certain absorption lines in the star's spectrum (0 or Ia+ - hypergiants, I - supergiants, II - bright giants, III - regular giants, IV - sub-giants, V - main-sequence stars, sd - sub-dwarfs, and D - white dwarfs).

Which of the following pairs is mismatched? DNA ligase joins segments of DNA Helicase unwinds double-strand DNA DNA polymerase m

ycow [4]

Answer:

DNA polymerase makes a molecule of RNA from a DNA template

Explanation:

DNA polymerase is an enzyme involved in the process of DNA replication. DNA replication replicates or synthesizes a new DNA replicate from the parental DNA.

The enzymes mentioned in the question perform a specified function which is matched with their description except for DNA polymerase as this enzyme is responsible for adding nucleotides to the synthesizing strand from the template strand f DNA.

Thus, the selected option is correct.

Explain two situations in which it would be important/useful to be able to predict the phenotype and/or genotype of offspring fr

Vinvika [58]

Answer:

The two situations in which it would be important/useful to be able to predict the phenotype and/or genotype of offspring from a cross include Genetic counseling before marriage so as to enlighten the individuals on the importance and to reduce the risk of having sickle cell offsprings.

The other reason is for paternity and maternity tests. The genotypes and phenotypes are important factors in knowing the paternity of individuals due to the knowledge of genotypic and phenotypic constituents of the individual.
