Answer:
False
Explanation:
Viscosity is a property of liquid that has resistance between liquid molecules. Those liquids having strong force of attraction between their particles has a viscosity whereas those liquid substances have weak intermolecular force of attraction between the particles has low viscosity. For example, water has low viscosity as compared to honey.
Genetic engineering:Pros: produces more food, makes organisms more fit, increases knowledge and knowledge is good.Cons: Some say it's: playing God, dangerous due to recombination of DNA, contamination of the gene pool, big pharma could take over the "means of production".
In-vitro fertilization: Pros: Allows people who couldn't have children to do so, increases knowledge and knowledge is good.Cons: Expensive (really expensive), can lead to overpopulation (minor), can be done irresponsibly (minor as everything can be).
Explanation:
Psi packaging Element is a cis-acting RNA element identified in the genomes of the retroviruses Human immunodeficiency virus (HIV) and Simian immunodeficiency virus (SIV) It is involved in regulating encapsidation of the retroviral RNA, an essential step in replication.
Answer:a) decreased chromatin condensation
Explanation:
During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.
The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.
Chromatin condensation is driven by condensins and interactions between histones.
Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.
Chemical manipulation as stated above is decreases the rate of chromatin condensation.
