Complete question:
Question 49 (1 point) The following questions refer to the description below. You have read that soapberry bugs, Jadera haematoloma, adapt to available food sources. For example, in southern Florida, soapberry bugs feed on seeds of a native plant, the balloon vine. In central Florida, the balloon vine is rare and soapberry bugs have switched to eating seeds of an introduced species, the golden rain tree. The seeds of the golden rain tree fruits are much closer to the fruit surface than the seeds of the native balloon vine fruit. As a result, natural selection results in beaks that are shorter in soapberry bugs that utilize golden rain tree fruits than those that feed on balloon vine fruit seeds.
What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group?

how do allosteric enzymes activate and inhibit chemical reactions in a living organism?
Answer:
Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.

Drag two black mice into the Parent 1 and Parent 2 boxes. Click Breed to view the five offspring of these parents. What do the offspring look like
Answer:
The correct answer is - All offsprings are black-furred mice.
Explanation:
In this case, the parent mice are black and a cross between these mice produces offspring one allele from both parents. Here, black fur is dominant over white fur.
All the babies are with dark fur colors, no whites as black is a dominant color, so it produces black due to cross between two true breeds.

¿A qué se refiere la sexualidad libre de coerción y violencia?
Para las mujeres y las niñas, el derecho a controlar su propio cuerpo y su sexualidad sin ningún tipo de discriminación, coerción o violencia es fundamental para su empoderamiento. Sin derechos sexuales, no pueden realizar sus derechos a la autodeterminación y la autonomía, ni pueden controlar otros aspectos de sus vidas. De hecho, son los intentos de controlar la sexualidad de las mujeres y las niñas los que dan como resultado muchos de los abusos de los derechos humanos que enfrentan a diario, incluida la violencia de género, el matrimonio forzado, la mutilación genital femenina y limitaciones en su movilidad, vestimenta y educación. , empleo y participación en la vida pública. Lo mismo ocurre con las lesbianas, los hombres gay, las personas bisexuales, las personas transgénero, las trabajadoras sexuales y otras personas que transgreden las normas sexuales y de género y que, como resultado, enfrentan un mayor riesgo de violencia, estigma y discriminación. Está claro: los derechos sexuales sustentan el disfrute de todos los demás derechos humanos y son un requisito previo para la igualdad y la justicia.
A nivel mundial, existe un gran debate sobre si definir los derechos sexuales y cómo hacerlo. IWHC cree que para superar algunas de las barreras políticas al reconocimiento, respeto, protección y cumplimiento de los derechos sexuales, necesitamos aclarar cuáles son.
IWHC, en colaboración con otras organizaciones líderes de derechos humanos y salud sexual, ha desarrollado la siguiente definición de trabajo de derechos sexuales:
Los derechos sexuales abarcan ciertos derechos humanos que ya están reconocidos en las leyes nacionales, documentos internacionales de derechos humanos y otros documentos de consenso. Se basan en el reconocimiento de que todas las personas tienen derecho, libres de coerción, violencia y discriminación de cualquier tipo, al más alto nivel posible de salud sexual; perseguir una vida sexual satisfactoria, segura y placentera; tener control y decidir libremente, y con el debido respeto a los derechos de los demás, sobre asuntos relacionados con su sexualidad, reproducción, orientación sexual, integridad corporal, elección de pareja e identidad de género; ya los servicios, educación e información, incluida la educación integral en sexualidad, necesarios para ello.

Moving the magnet faster would not produce more electricity when a magnet is moved.
What is magnet?A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field.
An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator.
Ferromagnetic materials are those that can be magnetized and are also those that are powerfully drawn to a magnet (or ferrimagnetic). These comprise some naturally occurring materials as well as the metals iron, nickel, and cobalt as well as their alloys.

What are the applications of CRISPR/Cas9-mediated Epigenetic Editing?
The CRISPR/Cas9 with the advantages of low cost and ease of use gives researchers the opportunity to manipulate the epigenome and observe its possible effects on cell function, development, and differentiation (Figure 1). Using non-active dCas9 (another type of Cas9 lacking nuclease activity but retaining DNA binding activity) fused enzymes such as DNA methylase, histone acetyltransferase, and deacetylase can be targeted to alter the epigenetic state of precise locations within the genome.
https://www.creative-biogene.com/crispr-cas9/solution/crispr-cas9-mediated-epigenetic-editing.html
Answer:
Applications:
- silence gene expression of target genes
- activate gene expression of target genes
- determine the role of DNA methylation and histone modifications (methylation, acetylation, etc) on specific regulatory sites (e.g., enhancer sequences)
Explanation:
The CRISPR/Cas9 system can be repurposed to edit the epigenome of living cells. For this purpose, it is required 1-to fuse a catalytically inactive 'dead' Cas9 enzyme with enzymes involved in epigenetic mechanisms (e.g., DNA methyltransferases, histone deacetylases, etc) capable of activating or deactivating gene expression, and 2-to design single-guide RNAs (sgRNAs) complementary to the sequence of interest (i.e., target sequences whose epigenome landscape we are trying to modify). For example, dCas9 gene has been fused with the DNA methyltransferase 3a (Dnmt3a) gene to create a dCas9-DNMT3A complex which can be combined with a specific sgRNA in order to study the effects of DNA methylation at a particular gene. These CRISPR/Cas9-mediated epigenome editing systems have shown to be very useful to understand how epigenome drives chromatin folding and dynamics at specific genomic sites (loci), and thus regulate gene expression at the transcriptional level.

Based on your understanding of nucleic acids, what type of bonds form between the CRISPR/guide RNA molecule and the target DNA
Answer:
The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds
Explanation:
The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.

A child is born with hemophilia (inherited as an X-linked recessive) and Klinefelter's syndrome to parents who both have normal blood clotting. In which parent (mother or father) and during which round of meiosis (I or II) did the nondisjunction event occur
Answer:
mother
Explanation:
Hemophilia is a sex-linked recessive disorder caused by a mutation in one of the genes responsible for encoding the clotting factor proteins (factor VIII or factor IX), which are located on the X chromosome. Moreover, the Klinefelter syndrome is caused by men having an additional X chromosome. In this case, the nondisjunction occurred from the mother because her gamete included an extra X, it is for that reason that all genes localized on the X chromosome, including the defective gene involved in hemophilia, can cause all of her sons to be affected by the disease in some generation. Thus, sister chromatids did not separate during meiosis (Anaphase II) and caused two copies of the defective allele for the hemophilia trait.
Imagine you are a plant breeder. Friends sent you two different varieties of a snapdragon flower; each have golden leaves rather than green leaves. (Wild-type snapdragon plants have green leaves.) A cross between the two different varieties of golden snapdragons always produces progeny that have green leaves. This is an example of:
Answer:
Complementation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.
In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.
Hence, the above breeding is an example of complementation.
Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response.
Bacteria cause bacterial infections. Viruses cause viral infections. Antibiotic medicines kill or keep many bacteria from growing but don't treat viruses.
What is a virus?
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.
The virus works by damaging the wall and the lining of the alveolus and capillaries. The debris from the damage, which is plasma protein accumulates on the alveolus wall and thickens the lining. As the walls' thicken, the transfer of oxygen to the red blood cells is impaired.
