When the source of a wave is moving relative to an observer of the wave, which of the following is true?
galina1969 [7]

Answer:

Observers ahead of the wave observe an apparent increase in wave frequency  

Explanation:

This is the Doppler Effect. The frequency of a wave increases when the source approaches the observer and decreases as the source recedes.

B, C, and D are wrong. Observers behind the source notice a decrease in frequency.

Using at least three sentences, describe the process of weathering, and explain how it can happen physically or
hoa [83]

Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock

olasank [31]
The above statement is very true. 
The inguinal hernia results from abnormal enlargement of the opening of the inguinal canal through which vessels, spermatic cord and nerves of male reproductive system pass (in males only). Hernias are protrusion of visceral through abdominal wall. They may be congenital or acquired ; Acquired occurs when a natural weakness is further aggravated by either a strain or a direct blow.

During replication, nucleotide bases are added to DNA strands in a ___ direction(s).
Alborosie

Nucleotide bases are added to DNA strands in a 5' to 3' direction.

What is DNA replication?

When a cell divides, DNA copies itself through a process called replication.

  • Generally speaking, DNA replication involves uncoiling the helix, strand separation by rupturing the hydrogen bonds between the complementary strands, and synthesis of two new strands through complimentary base pairing.
  • The origin of replication, which is a precise location in the DNA, is where replication starts.
  • From the point of origin, DNA replication is bidirectional.
  • The two parent DNA strands unwind and split apart at the origin of replication to generate two "Y-shaped" replication forks in order to start DNA replication.
  • These unwinding enzymes are known as DNA helicases.
  • The real location of DNA copying is at these replication forks.
  • Proteins that destabilize helices bind to the single-stranded areas to prevent the two strands from rejoining.
  • To reduce stress on the helical molecule during replication, enzymes known as topoisomerases cause breaks in the DNA and then reunite them.
  • The hydrogen bonding of free DNA nucleotides with those on each parent strand results in the formation of new complementary strands as the strands continue to unwind and split in both directions around the entire DNA molecule.
  • The new nucleotides are joined by DNA polymerases using phosphodiester bonds as they align themselves opposite each parent strand using hydrogen bonds.
  • Deoxynucleotide triphosphates, which are made up of a nitrogenous base called deoxyribose and three phosphates, are the actual nucleotides that are aligning through complementary base pairing.
  • Two of the phosphates are withdrawn to provide energy for bonding as the phosphodiester bond forms between the 3' OH of the previous nucleotide in the DNA strand and the 5' phosphate group of the next nucleotide.
  • In the end, two identical DNA molecules are created when each parent strand acts as a template for the synthesis of a complementary copy of itself.

Hence, nucleotide bases are added to DNA strands in a 5' to 3' direction.
