In a DNA double helix an adenine of one strand always pairs with a(n) _____ of the complementary strand, and a guanine of one st
notka56 [123]

Answer:

adenine pairs with Thymine  and guanine always pairs with cytosine respectively

Explanation:

In DNA nucleotide subunits, there are four nitrogenous bases:

  •    Adenine (A)
  •    Thymine (T)
  •    Cytosine (C)
  •    Guanine (G)

Each of these bases can be divided into two categories: purine bases and pyrimidine bases.

Adenine and guanine are examples of purine bases. This means their structure is a nitrogen-containing six atom ring joined with a nitrogen-containing five atom ring that share two atoms to combine the two rings.

Thymine and cytosine are examples of pyrimidine bases.

Note that  RNA replaces thymine with a different pyrimidine base called uracil (U).

The complementary base pairing rule, Chargaff's rule states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.

Humans are typically fueled by aerobic respiration. In which scenario might anaerobic respiration begin instead?
yan [13]

Answer:

C. After running 20 miles

Explanation:

Anaerobic respiration only occurs when an organism lacks all the oxygen we need to function. After running 20 miles, you will be out of breath, and you will have been using more energy than your respiratory system could produce alone. Due to this, your body will start using some of your energy stored within cells in order to continue functioning. This kind of respiration is basically 'burning calories'.

What could be inferred from suntans?
podryga [215]

Answer:

A tan might indicate sun damage to the skin.

Explanation:

Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.

A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
