Viruses with dsRNA genomes evolved a long time ago and can be found in parasitic relationships with species from a variety of taxa. What mechanism do eukaryotes use to combat such viruses?

Select all that apply.

RNA interference

posttranslational silencing

RNA-induced silencing

methylation of CpG islands

position effect variegation

genomic imprinting

Answer:

RNA interference

post translational silencing

RNA-induced silencing

Explanation:

Viruses are the pathogenic living organisms which invade the host cells of plants, animals, humans, and of other organisms to produce their own genetic material and progeny viruses.  The following are the methods using which the eukaryotic organisms can prevent themselves from infections.

1. RNA interference: In this viral RNA is cleaved by the use of complementary RNA sequence present in the genome of the host cell.

2. Post translational silencing: In this the gene products of viruses are silenced.

3. RNA induced silencing:  It involves the inhibition of replication of RNA of virus by the host cell machinery.

Whats the difference between complete dominance, codominance, and incomplete dominance?

Answers

In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Complete Dominance:

Complete dominance occurs when one allele in a pair completely masks or overrides the expression of the other allele. In this case, the dominant allele is expressed phenotypically, while the recessive allele remains unexpressed.

The heterozygous genotype (having two different alleles) will exhibit the same phenotype as the homozygous dominant genotype (having two copies of the dominant allele).

Codominance:

Codominance occurs when both alleles in a pair are expressed equally and simultaneously in the heterozygous condition. Both alleles contribute to the phenotype without blending or overriding each other.

As a result, the heterozygous individual exhibits a phenotype that shows both traits associated with the two alleles.

Incomplete Dominance:

Incomplete dominance occurs when the heterozygous phenotype is an intermediate or blended expression between the phenotypes of the two homozygous genotypes.

Neither allele is completely dominant over the other, resulting in a third phenotype that is a mixture or combination of the traits associated with each allele.

In summary, complete dominance involves one allele fully masking the expression of another, codominance involves both alleles being expressed equally, and incomplete dominance involves an intermediate phenotype that is a blend of the phenotypes associated with each allele.

How can we justify the conservation of energy using “system/surroundings” terminology for an open, closed, and isolated system?

Answers

Answer:

Energy can not be created nor destroyed.

Explanation:

Conservation of energy refers to the statement that energy can't be created nor destroyed, it can only be transformed into another form of energy. For example, if a pendulum swing to and fro motion, the kinetic energy is converted into potential energy. A closed system can exchange energy with its surroundings and transform that energy into heat and work. Total energy of an isolated system remains constant because no energy go out from the system.

Describe what is going wrong in the body of a person with this condition that is preventing the right molecules from getting to the body’s cells. (asthma)

Answers

Answer:

Asthma is a chronic, inflammatory disease of the airways with permanent hypersensitivity. In those with a corresponding disposition (with an overly sensitive bronchial system), the inflammation leads to attacks of breathlessness as a result of acute narrowing of the airways - a so-called bronchial obstruction. This narrowing of the airways is caused by increased secretion of mucus, spasms of the bronchial muscles and the formation of edema of the bronchial mucous membrane; it is reversible through treatment. About 1 of every 10 individuals has or had asthma at least once.

If 35% of the bases in a region of the Drosophila genome are guanine, what percentage in that region are cytosine bases?

Answers

Answer:

The correct answer is - 35%.

Explanation:

According to the rule of Chargaff the amount of adneine is equalls to thymine and the amount of guanine is equalls to cytosine in DNA. In a double-stranded DNA Adenine pairs with Thymine and cytosine pairs with Guanine.

So, Percentage of Adenine = percentage of Thymine

and, percentage of Cytosine = percentage of guanine

we know,  percentage of guanine = 35%

Thus, percentage of Cytosine will be 35% as well.

1) Bones tend to become brittle with age. A disease called osteoporosis causes bones to become less dense and as a result, bones break more easily. Osteoporosis is more common among older women, because they produce less of a hormone called estrogen, which aids in bone formation. Many doctors hypothesize that older women who take estrogen supplements will experience fewer broken bones. Part A: Describe how an experiment could be designed to test this hypothesis. Part B: What would be the outcome variable (dependent variable)?

Answers

Answer:

A) A Randomized Control Trial Experiment is done

B) Dependent Variable is Bone Mineral Density

Explanation:

Experimental Design:

Subjects (women) of the same age bracket (say 60-70) and having approximately the same baseline estrogen level, are recruited for the experiment, and randomly assigned into two groups of an equal number of subjects each; the test group and the control group.

The Test group is given a certain amount of estrogen supplements throughout the period of the study

The control group is given a placebo, identical to the supplements given to the test group, but without any medical significance.

Every other factor is held constant for both groups of subject throughout the period of the experiment.

After, the period of the study, the Bone Mineral Density is measured in the subjects. The Bone Mineral Density is a Radiographic Test that detects the amount of light the bone can absorb, and this is directly proportional to the health of bones. One with osteoporosis will have a less dense bone than one without Osteoporosis.

B) From the experimental design above, the independent variable is; presence or absence of estrogen supplements, while the outcome/dependent variable is Bone Mineral Density.

. There are many diseases that affect signal transmission along neural pathways. These includemultiple sclerosis (MS), myasthenia gravis, and amyotrophic lateral sclerosis (ALS or 'LouGehrig's Disease). Often, a component of these afflictions is a malformation or degenerationof the myelin sheath. MS is a demyelinating disease, which means that the axons of neuronsare intact but the myelin sheaths are damaged. Why would loss or damage to the myelinsheath be a problem for signal transmission, even if the axon was intact

Answers

Answer:

In neurons that are enveloped by myelin sheath, the nerve stimulus or neuronal action potential is transmitted in a saltatory way, that is, this action potential jumps in the spaces not surrounded by the myelin sheath and it is in this way that it is transmits much more efficient and faster.

Explanation:

Myelin neurons are those that are covered by myelin sheaths, this sheath is formed mainly by fatty acids, these fatty acids generate an alternate isolation along the axon so that the stimulus diffuses through the bare areas where they will have ionic channels premises in order to generate the potential for action.

If this myelin sheath disappears, not only is the response slower, but it is rendered incapable because an axon that does not have ion channels to spread the signal is discovered in the external environment.

1.¿Por qué es apropiado decir que casi todos los seres vivos dependen de la energía solar?Sara acaba de dar a luz a un bebé y esta agotada. Su amiga esta estudiando biología y evaluando el proceso de la fotosíntesis. 2.Sara decide sacar a su bebe al sol, en vez de darle leche, aludiendo que el bebé puede obtener energía de la luz solar. ¿Es esta una buena idea? ¿Por qué no puede el bebe utilizar la energía solar para producir ATP? No olvides incluir los organelos y procesos necesarios para la producción de ATP y de identificar al bebé de Sara como autótrofo o heterótrofo. En tu respuesta, contesta las siguientes preguntas. ¿Cuales son las diferencias entre la fotosintesis y la respiración celular? ¿Por qué no pueden los seres humanos procesar la energía solar y convertirla en energía química?

Answers

Answer:

1. La energía solar es la fuente principal de energía utilizada por organismos autótrofos para producir energía en forma de ATP a partir del proceso de fotosíntesis y almacenar esta energía en forma de enlaces químicos presentes en nutrientes orgánicos específicos. Los organismos autótrofos son fundamentales en la cadena alimenticia porque ellos representan la principal fuente alimento de organismos heterotrófos, con lo cual sustentando toda la vida en la tierra.  

2. No, esta no es una buena idea porque los animales y seres humanos (incluyendo el bebe de Sara) son organismos heterótrofos, es decir, obtienen energía mediante el proceso de respiración celular, a diferencia de organismos autótrofos que almacenan energía a partir del proceso de fotosíntesis el cual requiere de la utilización de la energía solar. Tanto en la fotosíntesis como en la respiración celular los organismos producen una molécula llamada Adenosina trifosfato (ATP), la cual es considerada como la moneda energética de la célula porque sus enlaces químicos almacenan energía la cual es utlizada para diversos procesos celulares. Los autótrofos fotosintéticos poseen cloroplastos que son los orgánulos celulares encargados de capturar energía lumínica para sintetizar ATP, el cual es posteriormente utlilizado para sintetizar carbohidratos. Por otra parte, en organismos heterótrofos, las mitocondrias son las organlelas encargadas de producir la mayor cantidad de ATP generada durante el proceso de respiración celular, el cual requiere del combustible metabólico provisto por los alimentos.
