Answer:

The particles with high kenetic energy

Explanation:

The first particles to evaporate from a liquid are those with the highest kinetic energy. When a liquid absorbs thermal or sound energy, its molecules speed up giving them higher kinetic energy. Typically, the particles or molecules at or just under the surface of the liquid escape into the gas phases first

kupik [55]

Answer:

The protein is targeted to Golgi apparatus.

Explanation:

Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.  

Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.
