Answer: increase heartbeat

Explanation:

Just as during exercise, holding your breath for 5 Minutes will increase levels of CO2 in your BLOOD.

Then, the body tries to wash out the excess CARBON DIOXIDE while providing FRESH OXYGEN. Your heartbeat rate will also INCREASE in order to pump your blood and properly "ventilate" your muscles.

So, holding your breath for 5 minutes will INCREASE heartbeat.

1. The <span>conclusion that can be made about the results of your first cross between a homozygous red bull (RR) and a heterozygous red cow (Rr) is shown below : 
You supposed to make a punnet square, so (picture)
</span>Than you will get that the first generation will be 50% homozygous dominant
and 50% heterozygous which lead us to conclusion :
<span>Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote). 
</span>
2. Conclusion about the results of your second cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr) is shown in the second picture. And you can see that <span>in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

3. Conclusion about </span>the results of your third cross between a homozygous white bull (rr) and a homozygous white cow (rr) are shown in the third picture. In this case you can see the result of <span> 100% (homozygous recessive).</span>

In the multiple-allele series that determines coat color in rabbits, c+ encodes agouti, cch encodes chinchilla, and ch encodes H
LekaFEV [45]

Answer:

1/4

Explanation:

Dominance within this multiple-allele series is c+ (agouti) > cch (chinchilla) > ch (himalayan).

A cross between c+/ch x cch/ch  was done.

<u>The possible genotypes of the offspring are:</u>

  • c+/cch: agouti
  • c+/ch: agouti
  • ch/cch: chinchilla
  • ch/ch: himalayan

So 1/4 of the progeny will be chinchilla.
