D. before cells without a true nucleus
I believe you mean mid-ocean ridge?
If so, true.
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.
This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
Answer:
Option C. As microscopes became more powerful, scientists could see additional structures and functions within the cell.
Explanation:
Light microscope is also called optical microscope which is used to see very small objects which can't be seen through naked eyes. The magnification power of light microscope is 1000x which means light microscope show the object 1000 times greater than its original size. Due to this magnification power, scientists are able to see many new features of the cell which cannot be seen with ordinary microscope.
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
Gan đóng vai trò trung tâm trong mọi quá trình trao đổi chất trong cơ thể. Trong quá trình chuyển hóa chất béo, các tế bào gan phân hủy chất béo và tạo ra năng lượng. Chúng cũng sản xuất khoảng 800 đến 1.000 ml mật mỗi ngày.
