A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of visible light shining on it EXCEPT for a group of frequencies that is perceived as red, which are REFLECTED. An apple looks red to us because it REFLECTS infrared waves.

Answer:

Reflects the red light

Explanation:

The optical physics says that whatever color we perceive for any object is the color of the light of any particular wavelength that is reflected by the object instead of observing. Rest all form of light waves except the one which is reflected are absorbed or transmitted by the object. For instance – leaves appear green because they reflect the green light and this is the reason that when plants are exposed to green light they are not able to photosynthesize.

Rna processing drag the correct labels under the diagrams to identify the events of rna processing.
Elena-2011 [213]
In the beginning <span>of the RNA strand as a cap, a modified guanine nucleotide is added. After this, there is a removal of those segments of the RNA strand that do not actually code for the protein. And those RNA’s segments that do code for the protein are reconnected. And forking a tail, extra adenine nucleotides are added to the end of the RNA strand. The mRNA or messenger RNA which is already completed will then leave the nucleus. This whole process is called the RNA processing. Before the RNA copy of a protein encoding can be transported out of the nucleus and translated into protein, it must be first be modified in several ways. A precursor of mRNA, pre-mRNA is the primary transcription product of a gene. </span>

What obstacles did Gerald ford go through
Mila [183]
<span>Challenges:
1. Vietnam
2. The worst economy since the Great Depression
3. Communist Europe (the Helsinki Accords)
4. Richard Nixon

One month after taking over the presidency, Ford pardoned Nixon. This caused a lot of controversy but Ford claimed he did it to save the nation from the prospect of a long, messy, and divisive trial.
In 1974, President Ford also offered clemency to those who evaded the draft during the Vietnam War if they would swear allegiance and perform two years of public service. Similarly, those who deserted during the war could return for two years in the branch they left to achieve clemency. However, Ford was criticized both by those who felt he was being to easy on the draft dodgers and those who had avoided the service because they felt they were in the right.

In 1974, Ford asked for aid to be sent to South Vietnam as fighting had resumed. Congress would not agree. In April 1975, Saigon fell and by 1976, North and South Vietnam were united into one country.

Ford escaped two assassination attempts, both by women. First on September 5, 1975, Lynette Fromme, a follower of Charles Manson, pointed a gun at him but did not fire. She was convicted of attempting to assassinate the president and sentenced to life in prison. The second attempt on Ford's life occurred on September 22, 1975 when Sara Jane Moore fired one shot that was deflected by a bystander. Moore was trying to prove herself to some radical friends with the assassination of the president. She was convicted of attempted assassination and sentenced to life in prison.</span>
