Plants use energy from sunlight to turn water and carbon dioxide from what they get into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. In photosynthesis, the energy in light is absorbed by photopigments.
The answer is Cutaneous Respiration. It is respiration through the surface of the skin. Cutaneous Respiration is used to supplement respiration alongside the use of their lungs. Cutaneous respiration<span> occurs primarily as a means of carbon dioxide exchange, with the majority of oxygen exchange occurring in the </span>lungs<span>. Frogs </span><span>take up most of their oxygen through </span>cutaneous respiration<span>, even if they possess </span>lungs<span>.</span>
DNA code is transffered to mRNA in the nucleus through a process called transcription.
Nucleus, the control center of the cell is the organelle which intiates, enables, and manages the various simplex. compound and complex cellular activities. It also stores the DNA of the cell which is then replicated and recopied over a hundredth and thousandth times over through cell division processes. In the nucleoplasm -nucleolus, the inner part of nucleus of a cell is where the DNA to mRNA and to protein; vice-versa happens.
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1
