The monomer of a nucleic acid (DNA is made up of multiple nucleic acids) is a nucleotoid.
I can’t see the image but I would guess animals such as deer or horse or elephants or any large animal have the ability to run over the rocks and turn them to smaller sediments
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>
Transporting blood under high pressure can be explained in the following steps:
- Contraction of the heart ventricles creates blood under high pressure
- High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
- The lumen of the arteries is narrow thus helping in maintaining high pressure
As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

DNA, or deoxyribonucleic acid, is a long chain molecule that plays a central role in life on earth. The information encoded in strands of DNA controls the genetic makeup of organisms. The DNA molecule has a backbone of sugars and phosphate groups off of which hang simpler units called nucleotide bases.
Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.
Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits.
Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.
