The oldest rocks of the ocean floor are approximately 200 million years old. These rocks are found in the western Pacific Ocean and are part of the western Pacific seafloor, known as the "Western Pacific Basin." This area contains some of the oldest oceanic crust on Earth.
The age of oceanic rocks is related to the process of plate tectonics, where new oceanic crust is continually formed at mid-ocean ridges through volcanic activity. As the oceanic plates move away from the ridges, they carry with them the older rocks towards the edges of the ocean basins. Over time, these older rocks get pushed back into the Earth's mantle at subduction zones, where tectonic plates converge.
This recycling process limits the age of the oceanic crust, and as a result, the oldest oceanic rocks we find today are generally around 200 million years old. This age is significantly younger compared to the age of the continental rocks, some of which are billions of years old.

Photosynthesis is a process in which light energy is converted to chemical energy.
Organisms, such as plants, that carry out photosynthesis absorb light from the Sun and, through a series of chemical reactions, produce sugar (glucose) molecules. These sugar molecules may be stored by the photosynthetic organism, or the chemical bonds in the sugar can be broken down by the organism to release energy for its life processes.
...in which light energy is converted to ____________ energy
sorry I couldn't help on that one, my mind went blank!
Answer:
The organisms like prokaryotes acts as decomposers of the environment and and they recycle nutrients back into the soil.
These nutrients are taken back from the soil by the plants (Eukaryotes) and then from plants these nutrients are transferred to the other animals.
So, of the prokaryotes will not recycle the nutrients back into the soil, then it will not be available to the other organisms as food.
A. through gamete formation
O
B. through genetic mutation
O
C. through meiosis
D. through mitosis
Answer:
The answer is D, Mitosis.
Explanation:
Mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. This also explains why your body cells are identical to each other.
