QUESTION 31 Chipmunk mitochondrial DNA was fingerprinted using the single primer amplified region technique (SPAR) and the PCR r
natima [27]

Answer:

It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)

Explanation:

The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.

How many moles would be equal to 224 g of CO2?
IrinaVladis [17]

Explanation:

Standard volume=22.4 L

It means that 1 mole of any atom, molecule or ion occupies 22.4 L of volume at STP (Standard Temperature and Pressure)

1 mole of CO2 = 22.4 L

Given volume = 224 mL = .224 L ( 1 L = 1000 mL)

No. of moles in .224 L = Given volume/Standard volume

= .224/22.4 = 0.01 mole

Ede4ka [16]

Answer: Scientists must be concerned about the impacts it causes on normal people due to aging.

Explanation:When a healthy human takes the growth hormone they do not any side effects or symptoms at the early stage. Once they start aging they have joint and muscle pain in legs and arms earlier than other people of their age and also result in diabetes, blood pressure and heart and lung diseases.

The Human growth Hormone can also cause tumors in brain and also indulge in growth  and development of Cancer Cells in people who has cancer or had been diagnosed before.So these are the main side effects that scientists should rectify in Human Growth Hormone.
