Set x = 0: -2y = 6 => y = -3, y-intercept is 3.

Setting x = 0, we get -4y = 12, so y = -3.

Setting x = 0 in the equation gives 5y = 20, thus y = 4. The y-intercept is 4.

Young's modulus (E) = Stress / Strain = 200 MPa / 0.01 = 20000 MPa = 2000 MPa.

Phosphorus is vital for energy transfer through ATP and is also important for nucleic acid synthesis.

Spindle fibers form during prophase to help separate the chromosomes during mitosis.

The plasma membrane regulates the entry and exit of substances in and out of the cell, maintaining homeostasis.

Convergent evolution occurs when unrelated organisms evolve similar traits due to similar environmental pressures.

The niche of a species is its role and position in its environment, including all interactions with biotic and abiotic factors.

Niche refers to the role and position a species has in its environment, including all interactions with biotic and abiotic factors.

The niche of an organism refers to its role and position in its environment, including all interactions with biotic and abiotic factors.

Species diversity refers to the variety of life in a particular habitat or ecosystem.

Biodiversity refers to the variety of life in the world or in a particular habitat.

Biology is the scientific study of living organisms, encompassing various sub-disciplines such as zoology and botany.

Biodiversity refers to the variety of life in the world or in a particular habitat or ecosystem.

Physisorption is characterized by a low heat of adsorption, typically less than 40 kJ/mol, due to weak van der Waals forces.

Chemisorption is characterized by the formation of a chemical bond between the adsorbate and the surface.

The reaction of ammonia with an alkyl halide primarily forms a primary amine.

Enzymes are primarily proteins that catalyze biochemical reactions.

DNA is classified as a nucleic acid, which stores and transmits genetic information.

RNA is classified as a nucleic acid, which plays a crucial role in protein synthesis.

NaCl is formed by the transfer of an electron from sodium to chlorine, resulting in an ionic bond.

A covalent bond is formed when two atoms share electrons.

A covalent bond is formed when two atoms share electrons to achieve stability.

A covalent bond is formed when two atoms share electrons to achieve stability.

A carbon-carbon double bond consists of one sigma bond and one pi bond, making it a double bond.

Alkenes contain at least one double bond between carbon atoms.

Alkynes contain at least one triple bond between carbon atoms.

O2 has a double bond, as two pairs of electrons are shared between the two oxygen atoms.
