Determine the x intervept of the line from equation 8x- 5y= -11

Physics
1 answer:
pav-90 [236]3 years ago
8 0
X intercept is when y = 0

Therefore substitute in y = 0,

8x - 5(0) = -11

8x = -11

x = -11 / 8

Therefore x intercept is at (-11/8 , 0)

What would occur if there was a gain-of-function mutation in the promoter for the cyclin E gene such that cyclin E protein was a
rjkz [21]

Answer:

b) Cells will pass through the G1/S checkpoint even if conditions are not ideal for cell division.

Explanation:

In the given problem, if there exists a gain-of-function mutation for the given cell, there would not be the formation of cyclin E when there is the possibility of cells movement via the checkpoint of the G1/S, even when there are non-deal conditions for the division of cell. Thus, the correct option in the lists of options is the option b.

When 0.1375 g of solid magnesium is burned in a constant-volume bomb calorimeter, the temperature increases by 1.126°C. The heat
Bumek [7]

Answer:

-24.76 kJ/mol

Explanation:

given,

mass of solid magnesium burned = 0.1375 g

the temperature increases by(ΔT) 1.126°C

heat capacity of of bomb calorimeter (C_{cal})= 3024 J/°C

heat absorbed by the calorimeter

    q_{cal} = C_{cal}\DeltaT

    q_{cal} = 3024 \times 1.126

    q_{cal} =3405.24\ J

    q_{cal} =3.405\ kJ

heat released by the reaction

    q_{rxn} = -q_{cal}

    q_{rxn} = -3.405\ kJ

energy density will be equal to heat released by the reaction divided by the mass of magnesium

Energy density = \dfrac{-3.405}{0.1375}

Energy density = -24.76 kJ/mol

heat given off by burning magnesium is equal to -24.76 kJ/mol

KatRina [158]

Answer:

1. C: 31/14 Si becomes 31/15 because a nuetron

2. A: 238  92U because the very long half-life means a very small rate of decay

3. D: Charge conservation is not satisfied

4. B: of the four nuclear decay processes only the α-decay changes the baryon number and does so in increments of four
