A virus infects the cell by attaching fibers of its protein tail to a specific receptor on the bacterial cell wall and then injecting the nucleic acid into the host, leaving the empty capsid outside.
In viruses with a membrane envelop, the viral envelop merges with the host cell membrane and is taken in to the host cell by a process called pinocytosis, then releases its nucleic acid inside the host cell to be intergraded with host cell genome.
Answer:
1-Tener en cuenta el tamaño del objeto a observar para utilizar la lente con el aumento correcto (es decir, 10 X, 40 X o 100 X)
2-Utilizar aceite de inmersión para ver objetos en 100 X
Explanation:
El microscopio óptico posee lentes (ocular y objetivo) los cuales permiten ampliar la imagen del objeto observado. El microscopio simple y el compuesto representan dos tipos de microscopios ópticos. El microscopio compuesto es aquel que utiliza más de una lente para aumentar la imagen observada, mientras que el microscopio simple usa una sola lente (la cual se denomina lupa). El microscopio óptico puede utilizar un aceite de inmersión que permite aumentar la resolución de la imagen a través de la inmersión de la lente objetivo. Es importante señalar que durante el enfocado de la muestra se debe tener sumo cuidado de no acercar demasiado la lente a la superficie del cubreobjeto, ya que esta puede dañarse.
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.
Answer;
-Change in a population through genetic variation over time.
Explanation;
-Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is the process of genetic change from one generation to the next and may be caused by several aspects including mutation, natural selection, genetic drift, thought and technology.
