  • It is elusive/slippery to the touch.
  • It has bitter taste.
  • It changes the shade of litmus paper (e.g., turn red litmus paper blue).
  • It responds with acids to shape salts.
  • It advances certain compound responses (base catalysis).

The allele for brown fur in mice (B) is dominant over the allele for white fur (b).
evablogger [386]

Answer:

Genotype: Bb (heterozygous)

Phenotype: brown fur

Explanation:

Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.

As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.

Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.

What major factors affected earth's changing climates?
Flura [38]
I just had this answer but it hasn't been graded. I put 1. Meteor impacts, 2. volcanic gases and 5. Milankovitch cycles. I didn't put earthquakes because I wouldn't think it would affect the climate changing since they just affect ground movement.
