Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.
Meningocele
Meningocele (MM) is known as meningeal cyst and it is the protrusion
of the membrane that cover the part of spinal cord through the defect in the
vertebral column. Thus, Meningocele (MM) is the least
common fom of spinal bifida and spina bifida is the bony defect in the
vertebral column through the meningeal membrane.
Answer: A storm or tornado
Explanation:
Answer:
Intertidal zone
Explanation:
Intertidal zone is present between low and high tide and hence, it can be above or below water. The zone is characterized by presence of nutrients and abundant oxygen as well as availability of light. The zone exhibits fluctuations in salinity and temperature as caused by waves.
