The student either drew the base-pairing showing adenine and thymine or guanine pairing with cytosine.

Further Explanation:

The nucleic acid makes the DNA. The nucleic acid is made up of nucleotides. Each nucleotide is made up of a phosphate group, deoxyribose, and a nitrogenous base. Gene is defined as the linear sequence of the nucleotides that are mainly encoded for a protein having a particular function. The alleles are defined as the variant type of the gene. DNA is mainly made up of the nucleotides and also contains genetic information in the genes. DNA has mainly four different types of a nitrogenous base  

  • Adenine
  • Cytosine  
  • Thymine
  • Guanine

The nitrogenous bases are divided into two groups called the pyrimidines and the purines. The pyrimidines include the thymine and cytosine; the purines are adenine and guanine.The nitrogenous bases in the double helix are bound together according to the base-pairing rule—adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The student either drew the base-pairing showing adenine and thymine or guanine pairing with cytosine.

A DNA molecule consists of two stands of nucleotides that wind around each other like a twisted ladder with a phosphate and sugar backbone. The  nitrogenous bases are divided into two groups called the pyrimidines and the purines. The pyrimidines include the thymine and cytosine, the purines are adenine and guanine.  The nitrogenous bases in the double helix are bound together according to the base pairing rule. Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The student either drew the base pairing showing adenine and thymine or guanine pairing with cytosine.

When a phosphate group is released ATP becomes
Marat540 [252]
This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a thirdphosphate group, becoming amolecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rdphosphate group

When we doing strawberry extraction,why do we have to remove the air as much as possible before we seal the bag?
AlladinOne [14]

Answer:

Explanation:

Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.

The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.

Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.

What happens to light when it changes mediums
ryzh [129]

Answer:

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction.
