Answer should be <span>Biomass</span>
Answer:
AA , Aa , Aa and aa
Explanation:
AA X aa gives 4 Aa (F1)
When F1 is crossed Aa x Aa gives AA ,
2 Aa and aa (F2 generation)
The question is incomplete as it does not have the options which are:
a) DNA
b) AGCT
c) PCR
d) SNP
Answer:
PCR (polymerase chain reaction)
Explanation:
The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.
The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.
In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.
Thus, PCR is correct.
Answer: True
Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.
About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.
CO2 + Hb ↔ HbCO2.
The reversible binding of C02 to the haemoglobin is due to the the partial pressure of carbondioxde. In the lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.
In addition C02 is transported by other means.
1. As bicarbonate 70% of the Co2 in the blood is transported and bicarbonate buffer.
CO2 + H2O CA ↔ H2CO3↔H+ + HCO3
2, As soluble carbon dioxide which dissolves directly in to the blood stream; this is about 7-10%
