Answer:
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Explanation:
Law of Motion says that every object that moves uniformly tends to stay in that state unless a force is applied to it. Force is equal to the mass of that object multiplied by its acceleration:
F = m × a
The unit of force is N = kg * m/s².
Q1: T<span>he acceleration of gravity on Planet Zorg is unknown:
a = ?
</span>We know:
F = 180 N
<span>m = 30 kg
</span><span>
Since F = m </span>× a, then:
a = F/m
a = 180 N/30kg
a = 180 kg*m/s² / 30 kg
a = 6 m/s².
So, the acceleration of gravity on Planet Zorg is <span>6 m/s².
Q2: Force needed to change the motion of the object on the Earth is unknown:
F = ?
We know:
a = 9.8 </span><span>m/s²
m = 30 kg
If F = m </span>× a, then:
F = 30 kg × 9.8 m/s²
F = 294 N
So, f<span>orce needed to change the motion of the object on the Earth is 294 N.</span>
I'm not certain on the reason it happens, but it can be lethal by stopping the heart from beating and, the lungs from contracting and expanding causing death by suffocation or cardiac arrest, also putting the body into shock.
<span>the glucose-sodium cotransporter in animals, Na+ moves back into the cell down its electrochemical gradient, providing the energy for glucose to move into the cell against its concentration gradient.
</span>It makes sense css <span> glucose is cotransported with Na+ ions</span>
<span>In cotransport, the energy required to move one solute against its concentration or electrochemical gradient is provided by an ion moving into the cell down its electrochemical gradient. </span>
