Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.
Explanation:
Answer:
Primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
Explanation:
DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.
Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.
Regarding the question above, the primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
Answer:
A.
Explanation:
increasing salinity decreases solubility of gas in water, therefore dissolved O2 concentration decreases.
Answer:
E
Explanation:
Gregor Mendel discovered the principles that governs heredity. In one of his experiments, he discovered that an organism receives two forms of a gene called ALLELE from each parent. He realized that one allele is capable of masking the expression of its variant pair in a gene. He called the allele that masks or is expressed, DOMINANT allele while the allele that is masked, RECESSIVE allele. He termed this principle the LAW OF DOMINANCE.
The above explained law of dominance is what applies in the question here. When the homozygous round allele and wrinkled allele were crossed, the allele for round seeds are dominant over the allele for wrinkled seeds (recessive) i.e. in a heterozygous state (combination of the different alleles), the round allele will mask the phenotypic expression of the wrinkled allele, expressing itself over it.
Answer:
Control of both RNA splicing and chromatin remodeling control of RNA splicing.
Explanation:
RNA is present as genetic material but in case of some viruses only. RNA contains the nitrogenous base ( adenine, guanine, uracil and cytosine), oxyribose sugar and phosphate group.
The bacteria do not have well developed nucleus so no chromatin remodification occurs in case of bacteria. Bacteria is devoid of introns and contains only exons in its RNA structure. The splicing process is not required in case of bacteria.
Thus, the correct answer is option (4).
