In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.
The total energy from an isolated system is constant; energy can be changed from one form to another, but can't be created or destroyed.
It’s A because when changing it to scientific notation it goes to 2.75 and when going to the left from the decimal point it is negative
The term aerobic exercise describes any type of exercise typically performed at moderate levels of intensity for extended periods of time that increases the heart rate. In such exercise, oxygen is used to "burn" fats and glucose in order to produce energy in the form of ATP, the basic energy carrier for all cells. Initially, glycogen is broken down to produce glucose, but in its absence, fat metabolism is initiated instead. Aerobic exercise is an exercise performed at a moderately high level of intensity over a long period of time. For example, running a long distance at a moderate pace.
Answer:
The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.
Explanation:
This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.
According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.
This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
