Answer:
The purple flower is a dominant trait.
It can be explained with the help of the law of dominance which states that the trait which expresses itself and masks the other in a heterozygous condition is called a dominant trait.
When two purebred parents for a particular trait (like flower color in this case) are crossed, it always results in a heterozygous offspring. The trait which is expressed in the heterozygous condition is said to be a dominant trait.
Like in this case, the offspring had purple flowers. Thus, the purple flower is a dominant trait.

Integral membrane proteins (intrinsic protein) are known to be a type of membrane protein that is attached permanently to the biological membrane. Also, they are made up of significant proteins that are encoded in the genome of the organism. Furthermore, trans-membrane proteins allow the transportation of specific substances across the membrane and they undergo significant changes in order to move substances across or through the membrane.
Answer:Both birth rate and death rate will decrease.
Explanation:
Demographic transition: The process whereby a country moves from high birth and death rates to relatively low birth and death rates.
The decline in death rate is due to better economic and social conditions of the country which leads to control of pre-existing diseases, better medical facilities,more food production,increased jobs,better sanitation and hence better quality of life.
Decline in birth rate is due to improved quality of life and also could be due to availability of family planning services in highly developed countries.Moreover access to education especially in female population has created awareness regarding birth control.
