Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.
( So basically there are 2 stages )
The purpose is to produce gametes or sex cells that will help later during sexual reproduction
it is two forces are unequal or unbalance
Option A: Postcranial changes in hominins that indicate bipedal locomotion include shortening and broadening of the ilium of the pelvic girdle.
Around 3 million years ago, bipedal locomotion in early hominins turned to be more effective. This adaption made the hominins more stable to hold their weight and walk upright. It also helped them to see longer distances in the green forests areas. They could take the advantage of hunting their food or protecting them from harmful predators. Adapting bipedal location expended lesser energy, thus allowing hominins to walk longer distances.
Over many generations now, bipedal location turned out to develop stronger and longer legs and feet so as to allow running and holding more weights. Additionally, the arms turned to be more adapted to hold the heavier things efficiently and to carry their newborns effectively.
Owing all these changes, adaption made to this kind of locomotion include shortening and broadening of the ilium of the pelvic girdle and developed a bowl-shape structure.
Thus, option A is the correct answer.

1. Both objects have mass and therefore have a gravitational force.
2. Lower mass objects have less gravitational force.
3. Higher mass objects have stronger gravitational force.
Explanation:
To solve this problem, we need a recap of the newton's law of universal gravitation:
The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."
F = ![\frac{G[tex]m_{1} m_{2}](https://tex.z-dn.net/?f=%5Cfrac%7BG%5Btex%5Dm_%7B1%7D%20m_%7B2%7D)
}{
}[/tex]
G = universal gravitational constant
m₁ = mass of object 1
m₂ = mass of object 2
r² = distances between the two masses
From this we can infer that, for gravitational force to exists, both objects must have mass.
Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.
