The question is incomplete. The complete question is attached below.
Answer:
1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.
2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.
3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .
4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
Answer:
Explanation:
Blood group AB has both A and B antigens, but no antibodies. Blood group B has B antigens with anti-A antibodies in the plasma. Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma
Answer:
Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.
Answer:Airedale Terrier is a Dog specie,the Airedale Terrier is the largest of all terrier breeds.
(1) Respiration
(2) Nutrition
(3) Reproduction
(4) Movement
(5) Irritability
Explanation: A living specie is a specie that poses all the characteristics of a living organisms such MOVEMENT, REPRODUCTION, NUTRITION, IRRITABILITY,GROWTH, EXCRETION, REPRODUCTION AND DEATH.
Respiration is the process through which living organisms take in oxygen in order to break down food for the release of energy and carbon dioxide.
Nutrition is the process of feeding or intake of nutrients Airedale Terrier feeds on both plants and animals ( OMNIVORES).
Reproduction is the process through which the younger generation are brought to life Airedale Terrier reproduce through Sexual reproduction.
Movement is the change of location,Airedale Terrier moves from one point to another.
Airedale Terrier responds to different stimuli ranging from sound,light,touch, taste etc.
Adaptation because organisms adapt to avoid extinction.
