Answer:
(01) D
(02) E,C.
Explanation:
(01) the growing number of people in the cities puts a strain on waste management efforts. If a city cannot effectively cope, this will mean poor management which will strain the condition of our environment further. it can cause diseases especially in poor areas.
C I think would be the best answer for this question!
Genotype is 1:2:1 (1 Homozygous tall, 2 heterozygous tall, 1 homozygous short)
Phenotype ratio is 3:1
The heterozygous Tt and recessive tt could produce short pea plants if they were crossed.
Explanation:
Genotype is the alleles present for a particular gene. In the Punnett square we can see there will be three tall pea plants and one short pea plant but they can be either homozygous or heterozygous.
While phenotype is the exhibited trait by particular allele that is 3 tall pea plants and one small pea plant.
If Tt and tt are crossed 50 per cent chances of short pea plant is there.
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
