Answer:

It can easily remove dirt.

Explanation:

When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.

Sever21 [200]

Answer:

The correct answer will be-pachytene, prophase I,

Explanation:

Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.

The tetrad structure is seen under the microscope during the pachytene substage of prophase I.

The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.

Thus, pachytene, prophase I is the correct answer.

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. Assume all
PolarNik [594]

Answer:

C) all chinchilla

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

  • The allele for full colour or agouti is  designated as C+.
  • Allele for mutant coat color  silvery- gray coat-chinchilla is Cch.
  • Allele for “Himalayan” coat is called ‘Ch
  • Albino rabbits have whole white coat and allele for this is c

If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:

P1:                                            chinchilla x chinchilla

P1:                                             Cch Cch    X   Cch Cch

F1:                                          Cch Cch       :       Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype  it means that all the offspring will have chinchilla phenotype that makes option C correct.

Hope it help
