C. because the oxidation of carbon compounds during cellular respiration produces energy, just like the burning of natural gas and organic compounds. I hope this helps!
The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.
On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.
The given cross represent the cross between purple (PP) and white (pp) pure breeds.
The correct answer is - A. Death rate.
We get the fertility rate from the birth rate and the death rate. More specifically, from the number of the children that are born in a given time frame (usually a year) we minus the number of the people that have died in the same time frame, so the difference between them gives us the fertility rate.
The fertility rate can be positive (in the difference is a positive number) and negative (if the difference is negative number).
Answer:
A. The plant would wilt.
Explanation:
In order to stay healthy and fresh, plants like every other living organism require certain substances. One of those substances is WATER, which the plant gets by absorption via the root hairs. The water circulates throughout the plant with the aid of a water-conducting vascular tissue called XYLEM. Without the xylem, water will not be transported throughout the plant.
The xylem tissue helps provide structural support to the plant as it helps the plant cell to be turgid. A non-functional xylem means the conduction of water is impossible, hence causing the plant cells to become flaccid and lose strength; a process called wiltering.
