brilliants [131]

Answer:

C. USA PATRIOT Act.

Explanation:

The USA PATRIOT Act of 2001 enables law enforcement officers to search emails, telephonic conversations, medical, library and financial records. The USA PATRIOT Act stands for Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act. This act was enforced into the law after the terrorist attack on the World Trade Center and the Pentagon on September 11, 2001.

Under this exception the police officers have permission to search email, telephonic conversations, medical, library and financial records without warrant, if there's any hint of possible threat.

Therefore, option C is correct.

If I breed a short for FF female with a short for Ff male then I will expect to see what type of offspring
Usimov [2.4K]
If being short is the dominant trait, then you should expect the offspring to also be short.

This is because the traits are spread out as four different possibilities. Either FF, FF, Ff, or Ff. If the dominant trait is being short, “F” then this would mask the recessive trait “f”.

The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence, such as
svp [43]
1. Red-shift, which is basically the Doppler Effect, but with light. Because stars in other galaxies appear to give off red light, this shows that they are moving away from us (Earth). Red light is on the far left of the Visible Light Spectrum, so things moving away from us appear to be red, while things moving towards us appear blue (the other end of the spectrum). This suggests that the universe is expanding all the time - and therefore it might have started from a single explosion - the Big Bang.

2. Cosmic Microwave Background Radiation (CMBR) has been found by scientists to be coming from all directions in space, and is suspected to be 'left over' energy from the Big Bang.
