Answer:
Same age stars is a mark of Galaxy formed by collapse
Explanation:
Before a galaxy can be formed, the materials that help in building the galaxy rotate at a speed, it's the come together and collapse by it self due to it's gravitational pull. When it's collapse globular are formed and it's away from it's nucleus. The clusters this give rise Halo stars which are stars of the same age.
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum makes an extensive internal system of membranes in the eukaryotic cells. It makes a system of tubes and sacs that run throughout the cytoplasm. The ER is connected to the nuclear envelop also and serves in the transport of substances and proteins throughout the cells with the help of transport vesicles. For instance, the proteins formed on the surface of rough ER are packed in vesicles that bud off from the surface of rough ER and are carried to the Golgi apparatus for processing.

Answer:
The correct answer will be option-D.
Explanation:
During the electron transport chain, an electrochemical gradient is established due to the movement of electrons.
The high number of protons gets accumulated in the intermembrane space of the mitochondria whereas less number of protons present in the matrix.
The protons are pushed from the outer membrane to matrix through ATP synthase where the movement of ATP causes synthase to spin and bind ADP and Pi to produce ATP.
Thus, option-D is the correct answer.
