Answer:

A. global temperatures drop several degrees after several massive volcanic eruptions

Explanation:

  • If any event causes widespread destruction of life on earth that would rapidly decrease the biodiversity, then such an event is called a mass extinction.
  • All the organisms living on the planet require an optimum temperature for their survival, besides the temperature also influences the geological activities such as the weather, rainfall patterns, survival of plants and hence the amount of oxygen and control of pollution.
  • Due to the importance of temperature, the drop in it globally would have a major impact on the living beigns.
  • Since a drop in global temperatures would affect the organisms all over the planet this will lead to mass extinction.

In guinea pigs, brown coat color allele (B) is dominant over red (b), and the solid color allele (S) is dominant over the spotte
Valentin [98]

Answer:

<h2>3/16</h2>

Explanation:

As given;

Brown coat color (B) is dominant over (b), so B is dominant over b.

Solid color (S) is dominant over the spotted(s), so S is dominant over s.

crossing between true breeding brown, solid colored guinea pig( BBSS) with red spotted pig( bbss)

so parents are  BBSS× bbss

gametes are, of parent-1; BS, and parent-2: bs

F1 is : BbSs,

cross between F1 and F1

F2 is : BBSS, BBSs, BbSS, BbSs............BBss..........Bbss........bbSS.......bbss etc

So red and solid color offspring are (bbS_) = 3/16
