Answer:
Transposon is a fragment or sequence of DNA that can move unregulated to any point in the cell genome, leading to a phenomenon called transposition.
Explanation:
Transposon is the name of what was previously known as jumping genes, being a DNA sequence capable of moving freely within a DNA molecule. A transposon can produce mutations by translocation, altering the total amount of nucleotide in DNA molecule.
Genetic changes that are linked to evolutionary processes can be due to the existence of transposons, since they can even induce chromosomal changes.
True statements: A (Water is made up of atoms bonded to form molecules) and D (The chemical formula for water is H₂O).
False statements: B (Water contains half as many hydrogen atoms as oxygen atoms) and C (Water molecules tend to push away from each other)
Let's examine each statement to determine its accuracy:
A) Water is made up of atoms bonded to form molecules.
True: Water is indeed composed of molecules. Each water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, forming the H₂O molecule.
B) Water contains half as many hydrogen atoms as oxygen atoms.
False: The chemical formula for water, H₂O, indicates that there are two hydrogen atoms for every one oxygen atom in a water molecule. Therefore, water contains twice as many hydrogen atoms as oxygen atoms.
C) Water molecules tend to push away from each other.
False: Water molecules exhibit a property called cohesion, where they are attracted to each other due to hydrogen bonding. This attraction causes water molecules to "stick" together rather than push away from each other. It's why water forms droplets and has a relatively high surface tension.
D) The chemical formula for water is H₂O.
True: The chemical formula H₂O accurately represents the composition of water, indicating that each water molecule consists of two hydrogen atoms and one oxygen atom.
The structure of water involves H₂O molecules, with each molecule consisting of two hydrogen atoms and one oxygen atom, and water molecules exhibit cohesion due to hydrogen bonding, causing them to attract and stick together.
