Answer: Abrasion
Definition: An area damaged by scraping or wearing away. Another word for abrasion is erosion.
Explanation: Abrasion is the breaking down and wearing away of rock material by the mechanical acqon of other rocks. Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. Also Rocks suspended in the ice of a glacier can cause abrasion of other rock on earths surface.
Answer:
The pulmonary artery carries oxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveolar and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.

Answer:
d. error-prone repair
Explanation:
DNA polymerases are the enzymes responsible for synthesizing DNA, not only making faithful replicas of our chromosomes, but also carrying out the necessary repairs for the proper maintenance of your genetic information. Either due to the intensity of the genotoxic damage or due to defects in the repair machinery, the ideal situation of having a pristine, original mold of DNA for copying is not always possible, which explains the existence of a special type of DNA polymerases, specialized in tolerating various DNA lesions through a copy process called "translesion synthesis" which is an "error-prone" or error-guaranteeing.
There is also a new human translesion DNA polymerase, perhaps the oldest of all, and that is capable of initiating the synthesis of new DNA chains acting as a primase. This enzyme, called PrimPol, is present in both cellular compartments that contain DNA (the nucleus and mitochondria). Through gene silencing experiments it was shown that PrimPol is necessary for mitochondrial DNA replication, probably tolerating the high oxidative damage associated with the respiratory activity of these organelles.
Answer:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth's crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
