Explanation:
Meiosis creates gametes/sex cells, such as the sperm and egg.
So, sperm cells are formed by meiosis.
Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.
Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.

Answer:
Scientists use volcanic activity data from this area to show the relationship between volcanic activity and lithospheric plate motion. Hot Spots and Plate Tectonics: A volcanic hot-spot is an area in the mantle from which heat rises in the form of a thermal plume from deep within the Earth. Higher heat and lower pressure at the base of the lithosphere melts rock and forms magma.
Explanation:
energy moves through everything really
I’m sorry if I get it wrong but I think it’s C for the first one and B for the second one
Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6. <em>They can reduce the biodiversity of crop plants.</em>
