You are on an alien planet where the names for substances and the units of measures are very unfamiliar.
enyata [817]

Given that

1 skvarnick = 45 quibs

3 quibs = 7 sleps

Now if we have 45 quibs it means we have you have one skvarnick

three quibs = 7 sleps

so one quib = 7/3 sleps

so 45 quibs = 7 X 45 / 3 = 105 sleps

A chef is cooking with a 2000-gram stainless steel skillet. Stainless steel has a specific heat capacity of 0.450 J/(g *oC). How
LuckyWell [14K]

Answer:

Q = 90,000 J

Explanation:

Given data:

Mass skillet = 2000 g

Specific heat capacity = 0.450 J/g.°C

Energy required to raise temperature = ?

Initial temperature = 25°C

Final temperature = 125°C

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 125°C - 25°C

ΔT = 100°C

Q = 2000 g × 0.450 J/g.°C × 100°C

Q = 90,000 J

A scientist is breeding orange butterflies in the laboratory she notices a white butterfly in the latest generation of animals s
nevsk [136]

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.
