Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
Answer:
Parasympathetic nervous division
Explanation:
The parasympathetic division of nerves is a part of the autonomic nervous system which gets activated during the relax conditions.
The parasympathetic nervous system is the opposite of the sympathetic nervous system which gets activated during the stress condition.
The parasympathetic division gets activated when the level of cortisol and adrenaline gets decreased and the body responds by detoxifying, digesting and building immunity.
Thus, Parasympathetic nervous division is the correct answer.
Well, the ten biomes are:
Tropical Rainforests, Sub-tropical rainforests, savanna, tundra, arctic, boreal forests, conniferous forests, mediterrean, grassland, and desert
Answer:
The old idea that coronary heart disease is an infectious disease has gained popularity in recent years, and both viral and bacterial pathogens have been proposed to be associated with the inflammatory changes seen in atherosclerosis. Herpes group viruses, notably cytomegalovirus and herpes simplex type 1, have been associated with atherosclerosis and restenosis. Helicobacter pylori and dental infections have also been linked to atherogenesis, but the evidence seems to favor a respiratory, obligatory intracellular bacterium, Chlamydia pneumoniae. The association was originally found in seroepidemiological studies, but the actual presence of the pathogen in atherosclerotic lesions has been repeatedly demonstrated, and during past year the first successful animal experiments and encouraging preliminary intervention studies were published. The causal relationship has not yet been proven, but ongoing large intervention trials and continuing research on pathogenetic mechanisms may lead to the use of antimicrobial agents in the treatment of coronary heart disease in the future.

Answer:
The type of biodiversity been practiced is REFORESTATION .
Explanation:
Reforestation is the deliberate or natural process by which destroyed plants are re-planted in a particular forest. Deforestation usually brings about destruction of different plants species and this normally throws the ecosystem out of balance. The negative process can be reversed by mean of reforestation, in which new plants are planted in the place of the destroyed ones.
