The condition consisten with the protrusion of the membranous sac that encloses the abdominal contents through an opening in the abdominal wall into the umbilical cord is called Omphalocele
Answer:
Retroviruses or reverse transcriptase
Explanation:
Retroviruses are viruses in which the genetic material consists of ribonucleic acid (RNA) instead of deoxyribonucleic acid (DNA). Retroviruses produce an enzyme known as reverse transcriptase that uses RNA as a template to manufacture DNA, which can then be permanently integrated into the DNA of the infected host cells.

Answer:
Explanation:
Cannibalism is a very essential factor regulating population dynamics of four beetle. After some days of feeding, the flour becomes conditioned by the beetles which can affect rate of cannibalism
Adults have a relatively lower rate of cannibalism. While its highest rate of cannibalism is at larvae stage
Flour conditioning is caused by the accumulation of feces, pheromones and ethylquinone- thus is repellent produced by the beetles.
Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange.
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.
When an individual muscle fiber receives a threshold stimulus, it contracts as much as possible. ... a threshold stimulus is the minimum amount of energy needed to make a muscle fiber contract.
