Answer:
first option is not true
Explanation:
1 mole = 6.02 × 10²³ particles
C3H8 has 1 mole, so has 6.02 × 10²³ particles
5O2 has 5 moles so 5 × 6.02 × 10²³ = 3.01 × 10²⁴ particles
3CO2 has 3 moles so 3 × 6.02 × 10²³ = 1.806 × 10²⁴ particles
4H2O has 4 moles so 4 × 6.02 × 10²³ = 2.408 × 10²⁴ particles
Answer:
See explanation
Explanation:
A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.
Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.
Answer:
Annual rings of trees in temperate forests
Explanation:
because fluctuations in ground surface temperatures propagate slowly downwards into the earth as a "temperature wave".
Oceanic<span> crust tends to be denser and thinner than </span>continental<span> crust, so the denser</span>oceanic<span> crust gets bent and pulled under, or </span>subducted<span>, beneath the lighter and thicker </span>continental<span> crust. </span>
