Answer:
The root of a huge tree causes cracks in a rocky surface.---> biological Weathering.
Part of a cliff breaks and falls due to waves.----> mechanical weathering
Acid rain reacts with calcite present in limestone---> chemical weathering
Explanation:
The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved. Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands. Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.
Here's the matching of the scenarios with the types of weathering:
1. The root of a huge tree causes cracks in a rocky surface - Biological Weathering
2. Part of a cliff breaks and falls due to waves - Mechanical Weathering
3. Acid rain reacts with calcite present in limestone - Chemical Weathering
Biological Weathering: In this scenario, the root of a huge tree causes cracks in a rocky surface. Biological weathering refers to the breakdown of rocks caused by the activities of living organisms. The roots of the tree can exert pressure on the rocky surface as they grow, causing cracks and eventually breaking apart the rock.
Mechanical Weathering: Part of a cliff breaks and falls due to waves. Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. In this case, the force of the waves pounding against the cliff causes pieces of the rock to break off and fall.
Chemical Weathering: Acid rain reacts with calcite present in limestone. Chemical weathering involves the breakdown of rocks through chemical reactions. Acid rain, which is rainwater with a low pH due to the presence of acidic compounds, reacts with the calcite (a mineral in limestone) and causes it to dissolve, leading to the erosion and weakening of the limestone.
Each type of weathering plays a role in shaping the Earth's surface over time, and they often work together to break down rocks and minerals into smaller particles.

DNA is considered a good storage house for storing information due to the presence of nucleotide which helps in providing each cell a piece of information.
Further Explanation:
Genes are present in DNA and defined as the linear sequence of the nucleotides that are responsible for encoding a protein that has 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. Phosphate group, deoxyribose, and nitrogenous base altogether make up a nucleotide. DNA is mainly composed of four distinct types of nitrogenous base:
The arrangement of nucleotides in the DNA is mainly required for the structural and functional activities of an organism. That’s why DNA can be considered as a storage house for all the hereditary information of an organism. The sequence of nucleotides gives a specific function to the cell. Each nucleotide present in the DNA is specific to their functioning.

Keywords:
DNA, cytosine, guanine, thymine, adenine, hereditary information, arrangement, chromosome, gene, function, base, sequence, nucleotide, organism.
Its bases can be joined together in any order, like the letters of the alphabet can be strung to form different words. Option A
Due to the flexibility with which its bases—adenine, thymine, guanine, and cytosine—can be organized and linked along the DNA strand, DNA (deoxyribonucleic acid) is a good molecule for storing information. Similar to how the alphabet's letters may be put together to make various words, phrases, and paragraphs, this allows for the encoding of a wide variety of information.
DNA carries the genetic instructions for the growth, operation, and reproduction of living things in a precise order of nucleotide bases. Each base sequence holds a distinct piece of knowledge, such as the guidelines for constructing proteins or the management of different cellular operations.

Fossils are non living things, so the dinosaur fossil are non living thing.
A fossil is defined as the preserved remains, imprints or traces of something that once lived which includes the bones, shells, exoskeletons, stone traces of animals or microbes, amber, hair, petrified wood, and DNA from a past geological age. The totality of fossils is known as the fossil record.
Fossils are formed in many different ways by non-living things but are mostly formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as clay, sand or volcanic ash). Fossils show a tangible connection to life, landscapes, and climates of the past.
Thus, Fossils are non living things, so the dinosaur fossil are non living thing.

How common is it?
(high, high)
(low, low)
(high, low)
Answer:
Wind blows from areas of high pressure toward areas of low pressure.
Explanation:
Wind blows from areas of high pressure toward areas of low pressure.
it doesn't blow in a straight line and winds blow clockwise around an area of high pressure and counter-clockwise around low pressure.
