What is the difference between Mechanical and Chemical Weathering?What is the similarities between Mechanical and Chemical Weathering?

Answers

Carbon dioxide, oxygen, water, and acids may all cause chemical weathering. Mechanical weathering is the process of breaking a large rock into smaller pieces without changing the minerals in the rock. Mechanical weathering may be caused by frost, ice, plant roots, running water, or heat from the sun.

Final answer:

Mechanical weathering physically breaks down rocks without changing their composition, while chemical weathering alters the chemical composition. Both types of weathering are influenced by climate and contribute to the erosion of rocks.

Explanation:

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing the composition of the rock, while chemical weathering is the process that alters the chemical composition of rocks, causing them to break down. Mechanical weathering can occur through processes like frost wedging, abrasion, and exfoliation, whereas chemical weathering can occur through processes like oxidation, hydration, and carbonation.

Despite their differences, there are some similarities between mechanical and chemical weathering. Both processes can be influenced by climate and environmental conditions, such as temperature and rainfall. Additionally, both types of weathering contribute to the overall breakdown and erosion of rocks, ultimately shaping the Earth's surface.

Which biomolecule is made of the monomer "amino acids"? *6 points
O
Proteins
Nucleic Acids
O
Lipids
O
Carbohydrates

Answers

Answer:

Proteins

Explanation:

Final answer:

Proteins are the biomolecules made up of the monomer 'amino acids'. They are composed of specific sequences of amino acids and are responsible for nearly every task of cellular life. Option 1

Explanation:

The biomolecule that is made up of the monomer 'amino acids' is Proteins.

Proteins are one of the basic components of living cells and are composed of specific sequences of amino acids linked together by peptide bonds. These sequences determine the unique three-dimensional structures which in turn determine protein function.

Consequently, proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.

Answers

Answer:

B. They belong to the same species and C. They live in the same area.

Explanation:

This is an educated guess. If you think about it, if there was a population of humansss, we dont have the same parents nor the exact genes so to only two that make sense is those to (^ω^)
