(a) Describe why DNA replication is said to be a semiconservative process. Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism.

Answer:

is this multiple choice if not i have a better way of answering the third one like; as someone in her class has the flu the person touched the doorknob ,after a while she also touched it and without washing her hands  she touched her nose then the disease had  entered her body

YOU CAN SIMPLFY IT SINCE IF YOU TO BE IN A TEST YOU CANNOT REMEBER ALL THAT... :)

BUT I TRIED

Answer:

They die.

Explanation:

If genetically modified deer mice with white fur were accidentally released into the wild population of mice, they will die and decrease in population because these genetically modified deer mice with white fur can't survive harsh conditions of the mice. Their colour also attract the predators at night so they catch these genetically modified deer mice with white fur and feed on them which automatically decrease its population.

Based on the dihybrid cross, the genotype of the numbered item are as follows:

The genotype of an organism is the sum total of the genes inherited by the individual from the parents.

The genotype of an organism is made of the two parents alleles, where the organism receives an allele for each gene from each of the parents.

From the dihybrid cross, the genotype of the numbered item are as follows:

Answer:

- Hongos: antibiótico penicilina

- Bacterias: producción de insulina para uso humano

- Virus: vectores basados en adenovirus para el desarrollo de vacunas  

Explanation:

Los microorganismos son fundamentales para el desarrollo de diferentes tipos de aplicaciones industriales y medicinales. Por ejemplo, la penicilina es una sustancia sintetizada por el hongo Penicillium notatum, la cual es ampliamente utilizada como antibiótico debido a sus propiedades antibacterianas. Las penicilinas son antibióticos del grupo de los betalactámicos que tienen como núcleo un anillo central de beta-lactama, las cuales son capaces de destruir una amplia variedad de bacterias​. Por otra parte, las bacterias pueden ser usadas para la generación de moléculas orgánicas con fines médicos. Por ejemplo, cepas de Escherichia coli han sido modificadas mediante técnicas de ingeniería genética con el objetivo de producir insulina humana, una hormona central en el metabolismo de la glucosa. Mediante técnicas de recombinación genética, el gen responsable por sintetizar insulina humana ha sido introducido en bacterias. Las cepas de E. coli son relativamente fáciles de cultivar en el laboratorio y por lo tanto permiten obtener grandes cantidades de esta hormona (insulina). Finalmente, existen ciertas tipos de virus inocuos para nuestro organismo los cuales han sido recientemente utilizados como vectores para el desarrollo vacunas. Mediante esta técnica de ingeniería genética, un determinado vector viral (por ejemplo, un virus de la familia de los adenovirus) es modificado genéticamente con el objetivo de insertar un fragmento de un agente infeccioso o 'antígeno' el cual individualmente es incapaz de producir daño. Las vacunas diseñadas a partir de vectores virales son inofensivas para el organismo pero son capaces de desencadenar una respuesta inmune contra el antígeno recombinante, generando de este modo una memoria inmunitaria en contra el agente infeccioso.

Explanation:

Answer:

B. The allele frequency would stay relatively the same over time because there are no traits that are being selected for.

Explanation:

Like recombination, non-random mating can act as an ancillary process for natural selection to cause evolution to occur. Any departure from random mating upsets the equilibrium distribution of genotypes in a population. This will occur whether mate selection is positive or negative assortative.

Answer:

Peppermint oil and morning, peppermint oil and night, lavender oil and morning, lavender oil and night

Step-by-step explanation:

Fertilisers are substances, which could be organic or inorganic, that is added to soil to increase crop yield.

Pesticide can be defined as substances that are used to control pests in an environment. Example of a pesticide includes:

- fungicides,

- herbicides( these are used to kill unwanted plants) and

- insecticides.

From the existing knowledge that the time of day the fertilizer is applied, morning and night affects the pesticide, and the Company managers know that peppermint oil or lavender oil will be used.

The insects should be subjected to the following treatments to effectively compare all combinations of these choices listed above:

- Peppermint oil and morning,

- peppermint oil and night,

- lavender oil and morning,

- lavender oil and night

Answer

Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.

Answer:

50%

Explanation:

Olá. Primeiramente é necessário informar que perguntas em português devem ser postadas no campo "world Languagens". Isso porque esse não é o servidor basileiro e sim o servidor americano. Caso contrario, a sua pergunta pode nunca ser respondida e até mesmo excluida do site.

Em segundo lugar, para que seja possivel que você repsonda a essa pergunta você precisará preencher um Quadrado de Punnett, como mostra a figura abaixo.

Como você sabe, as mulheres possuem os cromossomos XX e os homens XY. Como a mulher apresentada na pergunta acima possui o alelo para o daltonismo, mas não apresenta daltonismo, podemos considerar que apenas um dos cromossomos dela possuem esse alelo. O alelo para o daltonismo é recessivo, sendo assim, podemos considerar que essa mulher possui os alelos XDXd. Homem com quem essa mulher se casa, não possui daltonismo, logo os alelos dele são XDY, como mostrado na figura.

Ao preencher o quadrado de Punnett, você verá que existe a possibilidade desse casal possuir duas filhas, uma delas pode possuir os alelos XDXd, igual a mãe e, portanto, ser carreadora do alelo para o daltonismo.

Sendo existe uma chance, em duas filhas desse casal ter uma filha carreadora de daltonismo. Isso é igual a 1/2, que resulta em 0,5, ou 50% de chances de ter uma filha carreadora de daltonismo.

La respuesta correcta para esta pregunta abierta es la siguiente.

Desafortunadamente, no anexaste opciones o incisos para responder la pregunta. Sin embargo, podemos comentar lo siguiente.

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD, SINO QUE TAMBIEN PUEDEN SER ENGAÑOSOS. A MENUDO SE DISFRAZAN CON NOMBRES QUE PUEDEN SER SABROSOS.

Es muy importante que seas cuidadoso con los alimentos que consumes como parte de tu alimentación. Muchas empresas, a través de sus marcas, comparten publicidad engañosa para atraer más clientes bajo la promesa de alimentos sabrosos y nutritivos. Y la verdad es que no. Te están engañando.

No hay nada como basar tu dieta diaria en frutas, verduras y un equilibrio entre proteínas, carbohidratos, azúcares naturales y grasas.

Si es necesario, consulta a tu médico o a un nutriólogo para que te expliquen qué tan malo pueden ser los alimentos con muchos químicos.

¿Son sabrosos? Sí, pero también están llenos de sal, grasas, azúcares en excesos que le hacen mucho daño a tu salud.

En México ya existe una ley que obliga a todos los productos colocar unas etiquetas de color negro con blanco en todos los productos con la leyenda: "exceso de sodio," "exceso en grasas," exceso en azúcar."

Esto, con el propósito de que la gente se entere antes de comprarlos.
