B)allow you to view the surface of cells in greater detail than electron microscopes. C)have a higher magnification capability because they use natural light. D)have a greater resolution available because they use white light. 2. To study the details of protein molecules on the surface of a cell, a biologist would likely use a A) compound light microscope. B) dissecting microscope. C) scanning electron microscope. D) transmission electron microscope. 3. What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x? (2 points) 40x 50x 400x 500x

Answers

Answer 1

Answer:

1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.

There are many advantages of light microscope over electron microscope such as:

It is easy to use as compared to the electron microscope.
It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.

2. The correct answer would be C) scanning electron microscope

Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.

3. The correct answer would be 400x

The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.

Thus, the magnification of the specimen would be 40*10 = 400x.

Answer 2

Answer:

1. The correct answer is A) allow you to view living cells, while electron microscopes do not. Light microscopes use visible light to illuminate specimens, which is less damaging to living cells compared to the electron beams used in electron microscopes.

The electron microscope

2. The correct answer is C) scanning electron microscope. Scanning electron microscopes (SEMs) are commonly used to study the details of protein molecules on the surface of cells. SEMs provide high-resolution images of the surface topography by scanning the specimen with a focused beam of electrons.

3. To calculate the total magnification of a compound light microscope, you multiply the magnification of the objective lens by the magnification of the ocular lens. In this case, the objective power is 40x, and the ocular lens power is 10x. Therefore, the magnification of the specimen viewed with this compound light microscope would be 40x * 10x = 400x. So, the correct answer is C) 400x.

The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _______ and the _______ of the conductor. A. length, speed
B. color, capacitance
C. resistance, current
D. distance, circumference

Answers

Answer:

Length and speed.

Explanation:

According to Faraday's law, the voltage induced in the conductor is equal to the product of magnetic field, length and speed of the conductor.

The formula to find the induced voltage in the conductor is:

ξ = Blv

Here, ξ= emf induced, B is magnetic field, l is the conductor length and v is the conductor speed.

From the above formula, it is clear that voltage of a conductor depends upon the length and speed of the conductor.

Thus, the correct answer is option (A)

The correct answer is A). Length, Speed.

Treadmiling contributes to actin based motility

Answers

La actina es una familia de proteínas globulares que forman los microfilamentos, uno de los tres componentes fundamentales del citoesqueleto de las células de los organismos eucariotas (también denominados eucariontes). Puede encontrarse comomonómero en forma libre, denominada actina G, o como parte de polímeros lineales denominados microfilamentos o actina F, que son esenciales para funciones celulares tan importantes como la movilidad y la contracción de la célula durante la división celular.

De la importancia capital de la actina da cuenta el hecho de que en el contenido proteico de una célula supone siempre un elevado porcentaje y que su secuencia está muy conservada, es decir, que ha cambiado muy poco a lo largo de la evolución.2 3Por ambas razones se puede decir que su estructura ha sido optimizada. Sobre ésta se pueden destacar dos rasgos peculiares: es una enzima que hidroliza ATP, la "moneda universal de la energía" de los procesos biológicos, haciéndolo muy lentamente. Pero al mismo tiempo necesita de esa molécula para mantener su integridad estructural. Adquiere su forma eficaz en un proceso de plegamiento casi dedicado. Además es la que establece más interacciones con otras proteínas de cuantas se conocen, lo que le permite desempeñar las más variadas funciones que alcanzan a casi todos los aspectos de la vida celular. La miosina es un ejemplo de proteína que une actina. Otro ejemplo es la vilina, que puede entrelazar la actina en haces o bien cortar los filamentos de actina, dependiendo de la concentración de catión calcio en su entorno.4
