What do most scientists think causes Bovine Spongiform Encephalopathy (Mad Cow Disease)?

Most scientists believe that it is caused by an abnormal protein in brain tissue, called a  prion, that can cause fatal disease when eaten.

Additionally, these types of proteins, as mentioned above, are caused by mutations in its actual production. Because all proteins have a specific shape, if one protein's shape is damaged in some way, then they will not be able to fulfill their purpose. In this case, the brain disease you mentioned has mutated and malformed proteins that are normally found to begin near the blood vessels in the neck.

A circuit with resistive elements of 220, 100, 57, and 43 produce what total resistance?
Korvikt [17]

The total resistance is 420 ohm.

A circuit with resistive elements of 220, 100, 57, and 43 produce what total resistance  

 R= 220+ 100+ 57+ 43

    = 420 Ω

What is resistance and its types?

Resistance is a measure of the opposition to current flow in an electrical circuit also known as ohmic resistance or electrical resistance. Ohms are measured as resistance, symbolized by the Greek letter omega (Ω). The ratio of the applied voltage to the current through the material is then known as resistance.

What causes resistance?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.

How do I calculate (30 points plus a brainlyest if correct)​
Nat2105 [25]

Answer:

Are you trying to calculate the net force?

If so, it would be 3 N Up.

This is because the 15 N forces from the left and right cancel out, leaving only the upwards 15 N force, and the 12 N force. However, we have to subtract 12 from 15, leaving the final net force to be 3 N Up.

Let me know if this helps!

19. When white light is incident on a prism, which one of the resulting color components will have the lowest index of refractio
ohaa [14]

Answer:

option A

Explanation:

When white light is incident on prism it bends and dispersed into different colors.

According to Cauchy equation, refractive index is inversely proportional to the wavelength of the light.

wavelength of the light in decreasing order

orange > yellow > green > blue

wavelength of the orange light is the highest.

Hence, the refractive index  of orange will be lowest.

The correct answer is option A

In an experiment involving pendulums, you want to see how changing the mass of the bob affects the period (amount of time) of a
Alborosie

Answer:

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.
