leptotene : homologus pairing is formed and chromosomes start to get closer to each other.
zygotene: synapsis is formed between homologus chromosomes which is apoint oattachment.
pachytene:crosing over occer that homologus chromosomes exchange THIER GENETIC METERIALS.
DIPLOTENE: chiasmata formation disapear which was formed in pachytene.
diakinasis:homologus chromosomes start to seperate from each other.
The answer is D. Roots, Stems, Leaves. The water enters the plant from the soil through the root hair cells, travels up the stem to the leaves where photosynthesis takes place.

Answer:
a. The cells are connected by gap junctions.
Explanation:
Gap junctions are the points of connection between the adjacent cells of animal tissues. These structures are formed by proteins which in turn form narrow channels in the plasma membranes of the neighboring cells. These channels allow the small molecules to pass from the cytoplasm of the one cell to that of another. The spread of dye to the neighboring animal cells would have occurred by gap junctions present between these cells.
Answer:
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
