Answer:

Las semejanzas en la forma de transmisión entre virus y bacterias son:

Ambas transmisiones pueden ser por vectores, estos vectores pueden ser le ser humano e insectos como los artrópodos.

Ambas transmisiones se pueden dar entre humano-humano a causa de que el humano funciona como hospedero de dichos microorganismos.

Ambas transmisiones a veces se suele dar por falta de higiene y cuidado personal.

Los mecanismos de transmisión pueden ser por diferentes vías en ambos casos, es decir por la vía parenteral (inyección o tranfusion de sangre infectada), vertical, o por la vía orofaringea por inhalación o ingestión del microorganismo.

Las diferencias entre la transmisión de los virus y las bacterias son:

Los virus pueden transmitirse de manera masiva y exponencial en poblaciones siendo así mucho mas rápido que las bacterias.

Las bacterias pueden estar inactivas en formas esporuladas en superficies mientras que los virus no presentan este mecanismo de supervivencia a situaciones muy extremas.

Los virus no presentan mecanismos de replicacion propio mientras que las bacterias si, es por eso que el virus solo puede ser multiplicado dentro del organismo humano por medio de la traducción de su ARN o ADN.

Los agentes pueden entrar al organismo por diferentes vías, la vía respiratoria por medio de gotas o inhalación, por medio de la vía digestiva comiendo o bebiendo alimentos contaminados, por medio de la vía ano-mano-boca, es decir  por mala higiene, transmisión sexual,  por medio de la vía vertical que es durante el momento del parto ya que el bebe contacta con la sangre de la madre en el canal de parto y por vía parental que es por inyección del agente por tranfusion mal controlada.

La prevención esta en tomar los recados necesarios como la desinfección de superficies, alimentos, hábitos de higiene y cuidado personal. Ademas de cumplir con el cronograma correspondiente del plan de vacunacion propio de cada país.

Explication:

Los virus y bacterias se diferencian en muchas cosas y aspectos pero lo mas importante es que los virus son proteinas dependientes de un organismo vivo para poder replicarse mientras que las bacterias se pueden replicar por si solas y hasta pueden formar colonias en superficies no vivas o inertes.

for each pair of compounds below , identify the one that would be expected to have more ionic character.explain you choice. (a)N
Tju [1.3M]

Answer:

a)NaBr

b)FCl

Explanation:

To identify which compound is more ionic we will calculate the electronegativity difference.

A) NaBr

Electronegativity of Na = 0.93

Electronegativity of Br = 2.96

Electronegativity difference = 2.96- 0.93 = 2.03

HBr

Electronegativity of H = 2.2

Electronegativity of Br = 2.96

Electronegativity difference = 2.96 - 2.2 = 0.76

NaBr have more ionic character because of large electronegativity difference.

B) BrCl

Electronegativity of Cl = 3.16

Electronegativity of Br = 2.96

Electronegativity difference = 3.16 - 2.96 = 0.2

FCl

Electronegativity of F = 3.98

Electronegativity of Br = 2.96

Electronegativity difference = 3.98 - 2.96 = 1.02

FCl have more ionic character because of large electronegativity difference.

Rank the metals from most reactive (1) to least reactive (3) silver, strontium, and technetium
Natasha2012 [34]

Answer:

1 = strontium

2 = technetium

3 = silver

Explanation:

Strontium is present in 2 group of periodic table. It is alkaline earth metal. It is most reactive element and can not found free in nature. it  is insoluble in water but react with water and form strontium hydroxide and hydrogen gas is also produced. It is radioactive element.

It is similar to the calcium and can incorporated into bones. The food rich with strontium is used to avoid the osteoporosis. It is found in leafy vegetables, grains, sea foods etc.

In given series strontium is highest in reactivity then technetium, while the technetium is more reactive than silver. The silver is less reactive as compared to both given elements.

How many grams of kcl are present in 85.0 ml of 2.10 m kcl? how many grams of kcl are present in 85.0 ml of 2.10 m kcl? 3.02 133
USPshnik [31]
Molarity (M) = moles of the solute (mol) / Volume of the solution (L)

The molarity of the given KCl solution = 2.10 M
Volume of the given KCl solution = 85.0 mL

Hence,
         2.10 M = Moles of KCl / 85.0 x 10⁻³ L
Moles of KCl = 2.10 M x 85.0 x 10⁻³ L
                     = 0.1785 mol

Moles (mol) = Mass (g) / Molar mass (g mol⁻¹)

Molar mass of KCl = 74.56 g mol⁻¹

Hence, 
  0.1785 mol = Mass of KCl / 74.56 g mol⁻¹
Mass of KCl = 0.1785 mol x 74.56 g mol⁻¹
                    = 13.30 g

Hence, mass of given KCl in 85.0 mL is 13.30 g.

According to the law of conservation of mass in a chemical reaction the total starting mass of all the reactants equals the tota
Ber [7]
I believe the correct answer true. According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products. This law states that mass cannot be created or be destroyed. So, the total mass that goes in a process should be equal to the mass that goes out the process.  This is true for chemical reactions and physical processes. It is Antoine Lavoisier who described this and is a basic principle used in physics and in chemistry. Mass, unlike energy, cannot be transformed to any form so however the transformation happens the mass should be constant.

Atoms form chemical bonds to satisfy the rule and to become .
soldi70 [24.7K]

Answer: Atoms form chemical bonds to satisfy the<u> Octet</u> rule and to become <u>stable.</u>

Explanation:

The tendency of atoms to attempt to get a noble gas configuration that is eight valence electrons is said to be octet rule.  This is done to attain noble gas configuration and stability.

In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.

For example : As we know that the sodium has one valence electron, so if giving it up then the result in the same electron configuration as the neon and chlorine has seven valence electrons, so if it takes one it will have eight and the result in the same electronic configuration as the argon which is stable.
