Answer:
Positive feedback system increases temperature of the earth surface which is good in a number of ways.
Explanation: For example, due to increase in the temperature of earth surface, melting of ice occurs in the mountainous area of the world. This stored form of water is changed into liquid form and flows down through streams and used by plants and animals. But more increase in temperature causes rise of sea level which is not good for areas near the sea.
Here are the reason why joining flocks will increase their chance of survival:
- Protection from predator
Their predator (such as falcons) can only get one bird at a time. Joining a flock will reduce their chance of being caught because they are moving in large unstoppable mass.
- Conserving heat
Being around the flock will help them maintain their body temperature to survive a harsh winter.

If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.
With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.
With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.
With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>
