Test Tube 4 - Sugar (Sucrose): Demetri fills the fourth test tube one-quarter full of sugar. He then adds water to the test tube until it is three-quarters full and stirs until the sugar dissolves. Demetri then inserts the test strip for 30 seconds and records its color.Test Tube 5 - Sugar (Sucrose) and Lactase Enzyme: Demetri fills the fifth test tube one-quarter full of sugar. He then adds the lactase-and-water solution until the test tube is three-quarters full. He thoroughly mixes the solution and inserts the test strip for 30 seconds. Demetri then records the color of the test strip.
Test Tube 6 - Sugar (Sucrose) and Heated Lactase Enzyme: Demetri fills the sixth test tube one-quarter full of sugar. He then adds the heated lactase-and-water solution until the test tube is three-quarters full. He thoroughly mixes the solution and inserts the test strip for 30 seconds. Demetri then records the color of the test strip.

According to the test strips, which of these sugar solutions contained glucose?

Answer:

In sample A,  

The percentage of thymine or T is 20.5 %. A = T, so the percentage of A will also be 20.5 %.  

Thus, A + T = 20.5 + 20.5 = 41 %

Therefore, G + C = 100 - 41 = 59 %

So, G = 59 /2 = 29.5 %

Also. G = C = 29.5 %

In sample B,  

The percentage of Thymine or T is 30.7 %. As A = T, so A will also be 30.7 %.  

Thus, A + T = 30.7 + 30.7 = 61.4 %

Also, G + C = 100 - 61.4 = 38.6 %

So, G = 38.6 / 2 = 19.3 %

Therefore, C will also be 19.3 %. As GC content is more found in the sample A, that is, 59 %. Hence, the sample A will possess the higher temperature to denature in comparison to B.  

Answer:

Explanation:

A) to determine amino acid sequence of the protein produced by that gene. We will use cDNA library, we will hybridize given part of DNA sequence ( as this part only contains exon part). Than we will isolate the hybridize part and translate this sequence using generic coding table.

B) for determine presence or absence of introns in gene used isolated cDNA in first question. Now we will add this cDNA to DNA library. Here cDNA due to complementary mature binds with DNA. If cDNA binds completely with gene with out looping part of gene it shows that gene is having only exons .

And if along with hybridization part some looped part present in between-- it shows both exons and intron are present.

C) for determining alternative splicing we will use cDNA library.

d) to determine length of mature mRNA which includes both the UTR and poly A sequence we will go for cDNA cloning and look for particular cDNA complementary to DNA segments. And later we isolate that cDNA and examine its whole length

E) to determine which cells in the tribble body express this particular mRNA . We use fluorescent tagged small DNA part provided. Then we will add this DNA probe to supplied tribes. The cells which are expressing , will have cDNA will bind to probe and florescent can be detected. Cells which are not expressing that gene, here probe will not bind and no fluorescence.  

F) to determine that whose blood strain is this. We will do VBTR profiling . Which VNTR profiling similar to belief stain help to determine which blood stain is this.

Answer:

200 to 500 milliseconds

Explanation:

Attentional blink is a phenomenon that puts time-related limitations to the ability to utilize visual attention. When an individual must identify two visual stimuli presented one after another, the accuracy is very poor for the second stimulus if it occurs within 200 to 500 milliseconds of the first stimulus.

So, in our question, the gap is filled by 200 to 500 milliseconds.

Answer:

los aspectos más relevantes son aquellos destinados a fomentar acciones conjuntas con el objetivo de revertir problemas ambientales y plantear políticas públicas asociadas al desarrollo sostenible en ciertas regiones del planeta

Explanation:

El informe de Brundtland es un documento desarrollado en 1987 con el propósito de abordar el problema del desarrollo económico y social desde una perspectiva medioambiental, planteando así por primera vez el concepto de 'desarrollo sostenible'. El documento analiza con una mirada crítica las políticas de desarrollo económico que se llevan a cabo sin considerar la sustentabilidad medioambiental. El informe lleva el nombre Brundtland en honor a la primera ministra de Noruega durante parte de 1980, Gro Harlem Brundtland. El documento fue revelador para su época ya que visibilizó el problema del desarrollo económico y social en función de la sustentabilidad de nuestro planeta. Un punto importante a tener en cuenta del informe es que a fines de sustentabilidad medioambiental la población mundial no podría seguir creciendo a niveles exponenciales como los observados actualmente o a fines del siglo pasado, prediciendo que este valor se debería estabilizar en un valor entre los 7.700 millones y 14.200 millones de personas.

Answer:

Mast Cells

Explanation:

Mast cells release histamine in the blood stream, when they detect a substance that triggers an allergic reaction, also called an allergen.

Answer:

Comparative genomics is a field of biological research in which researchers use a variety of tools to compare the complete genome sequences of different species. By carefully comparing characteristics that define various organisms, researchers can pinpoint regions of similarity and difference.

Functional genomics is a field of molecular biology that attempts to describe gene (and protein) functions and interactions. Functional genomics make use of the vast data generated by genomic and transcriptomic projects (such as genome sequencing projects and RNA sequencing).
