Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
I just found this on google
The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.
The functions that take place within the eukaryotic cytoplasm are diverse:
- Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm. The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.
- Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.
- Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.
On the other hand, in plant cells, the cell wall is located outside the cell membrane.

Answer:
Persuasion
Explanation:
Propaganda is manipulation with public opinion, it is a technique of influencing people’s actions through arguments and persuasion. Propaganda can be done in various ways and some of them are oral, written and visual ways.
As propaganda’s purpose is to convince people in something, techniques used for propaganda are founded on psychological research. People who use propaganda use arguments that don’t have to be valid but have to be convincing.
The correct option is D.
During the process of photosynthesis, carbon dioxide and water react together in the presence of sunlight energy to form glucose and oxygen. Glucose and oxygen are the product of photosynthesis. The chemical formula for glucose is C6H12O6 and that of oxygen is O2.
I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
