Why must powder be used after cyanoacrylate?

Answers

Answer 1

Answer:

Explanation:

Cyanoacrylate or super glue fuming is used to develop latent fingerprints and make them visible.Fingerprint powders, however, adhere to the sweat and therefore the powders have a difficult time adhering to only the amino acids, proteins and fatty acids.

In polygenic inheritance, each of the genes controlling a trait will have exactly the same influence over the trait. Group of answer choices Yes since all genes having to do with a trait always have the exact same influence on a trait. No since different genes will exert varying degrees of influence on the trait None of the other responses are satisfactory answers. No since all traits are only controlled by one gene with two alleles.

Answers

Answer:

No, since different genes will exert varying degrees of influence on the trait

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.  

Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.

The difference between a food chain and a food web:

Food Chain

- Only one possible direct line of energy going through organisms

- Consists of usually 4-6 organisms

Food Web

- Multiple links  that branch off in a web-like form, with some organisms being interconnected with each other.

The answer is the third option: A food chain represents one possible pathway that energy and matter can take in an ecosystem. A food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem.

A plasmid contains a multiple cloning site inside the coding region of the lacZgene and also contains an ampicillin resistance gene at a separate locus. When cells are transformed with a successfully recombinant plasmid containing a piece of DNA cloned into the multiple cloning site, what color will the colonies be when grown on an agar plate containing ampicillin and X-gal

Answers

Answer:

The correct option is white.

Explanation:

As the options are not given, the options are found online and are as follows;

(a.) green (b.) white (c.) colonies will not grow (d.) blue (e.) clear

Out of this, white is the true option because in recombinant plasmid lac Z gene is disturbed and cannot produce beta galactosidase enzyme and there is no hydrolysis of x gal and no blue so recombinant plasmid gives white colonies)

A student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of white-flowered poinsettias. The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records 64 red-flowered plants, 107 pink-flowered plants and 53 white-flowered plants. What is the inheritance pattern for flower color in these poinsettias

Answers

Answer:

The correct answer is - incomplete dominance.

Explanation:

The incomplete dominance is the pattern of inheritance where the recessive allele is not completely masked by the dominant allele in the heterozygous condition and makes a mixed or blend expression of both dominant and recessive traits.

In the given question, the pattern for the flower color is incomplete dominance as in the cross between the red and white flower poinsettias produce pink instead of red in F1 generation where the condition is heterozygous. The phenotypic ratio of in F2 generation in this type of inheritance is 1:2:1 which is approximately similar in this case 64:107:53.

Which of the following is an example of genomic imprinting in humans? Which of the following is an example of genomic imprinting in humans? A random pattern of autosomal allele inactivation is observed. In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed. The maternal and paternal alleles of a gene pair are both expressed. Human males have only one Y-chromosome and one X-chromosome. One of the two X-chromosomes in females is randomly expressed and the other is repressed.

Answers

Answer:

In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed.

Explanation:

Genomic imprinting is an epigenetic phenomenon where alleles are differentially expressed depending on their parental origin (for example, paternally expressed when it is inherited from the father). Genomic imprinting is controlled by epigenetic modifications (for example, DNA methylation, histone acetylation, etc) which works together to preferentially activate the expression of the allele inherited from one parent and simultaneously silence or “​imprint” the expression of the allele inherited from the other parent. In humans, an example of genomic imprinting is the case of the insulin-like growth factor 2 (Igf2) gene, which is maternally imprinted (repressed), thereby this gene is only expressed from the paternal allele.
