Answer:
The subatomic particles in the nucleus of a carbon atom are protons and neutrons.
Explanation:
The atomic nucleus contains protons and usually neutrons (except for hydrogen-1 (protium) atoms. The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number 6. So all atoms of carbon have 6 protons in their atomic nuclei. Carbon atoms also contain neutrons in their atomic nuclei, which may number 6, 7, or 8.
Answer:
At the time of liberation, it becomes 2 celled, with a small generative cell and a vegetative cell. In the nutrient medium, the pollen grain germinates. The tube cell enlarges and comes out of the pollen grain through one of the germ pores to form a pollen tube. The tube nucleus descends to the tip of the pollen tube.
Explanation:
The rock cycle is a cycle that rocks go through which involves melting, cooling, pressure, erosion, and other stages. Starting with a volcanic eruption, the lava turns into igneous rock, that can be melted into magma again, or can be crushed and pressed into other rocks beneath the crust to form metamorphic rock, or can be broken down by erosion and other factors. For the sake of it, let's say the rock got broken down, it turns into sediment that collects in areas and get layered and pressed, and layered, and pressed some more into a sedimentary rock. That rock can be broken down again, or melted, or pressed with heat and pressure. But let's say it went under the crust with other rocks, mixed with heat, pressure, and other types of rock to become metamorphic rock. Now let's say that metamorphic rock found it's way to a volcano, got melted, and erupted, and cooled to get back to a igneous rock. And the cycle never ends.
Answer:
D
Explanation:
once again sorry if you get it wrong but we were learning about mutations in class so i think so
ehehe
Force of gravity drives to the process of subduction zones where dense pieces of oceanic crust are pulled downward toward the mantle.
We can term subduction as the process by which oceanic crust sinks into the mantle when it collides with continental crust. Subduction destroys oceanic crust by forcing it to the mantle where it melts.
Oceanic crust is said to be subducted because they contain more mafic minerals and again it has convergent boundaries. When there is a divergent between continental crust one oceanic crust sinks into the mantle.
