They would be metamorphic rocks because they form under high heat and pressure. Sedimentary rocks are formed under high pressure. Igneous rocks are formed under high heat.
There are kingdoms and the kingdoms represent different organisms.
Answer:
Petal color in snapdragon is an example of incomplete dominance and deviates from Mendel's law of dominance.
Skin color in humans exhibits a continuous variation and is regulated by more than one genetic loci.
Explanation:
Two alleles of a gene do not always exhibit the dominant-recessive inheritance as shown by Mendel. The alleles controlling the petal color in Snapdragon exhibit incomplete dominance since the allele "R" is not able to produce enough pigment in heterozygous condition to completely mask the effect of the recessive allele "r" Therefore, the heterozygous genotype "Rr" gives pink color to petals.
Mendel showed that each genetic trait is regulated by one gene and exhibit discontinuous variations. This is not followed by skin color in humans which is a polygenic trait with multiple genes regulating it. Here, a range of phenotype is present which is regulated by the sum total of the dominant alleles of all the genes involved controlling the melanin production.
Neonates are at a higher risk of developing respiratory complications upon administering general anesthesia
Explanation:
Anesthesia can lead to a number of perioperative and postoperative respiratory complications especially in neonates. Neonates may require varying levels and types of anesthesia for various conditions starting from central line or VP shunt placement, tracheostomy or gastrostomy tube placements, any excisions, circumscision and any other surgical procedures.
The immature neonatal respiratory system makes neonatal anesthesia a difficult task due to:
Anatomically, the airways are small and alveoli network is immature.
Physiologically, neonatal metabolic rate is very high with more oxygen consumption than adults
Functionally, the lung mechanism is also immature, smaller upper airway resistance and higher lower airway resistance which causes collapse.
Hence, proper care should be taken while anesthetizing neonates with proper communication with the healthcare team including pediatric surgeons, pulmonologist, cardiologist, nursing care, pharmacists etc
