The obligate parasite depends on strigolactones for its seed germination rather than karrikins. The plant emits strigolactone from its roots into the surrounding soil, which stimulates the germination of the parasitic weed's seeds. Thus, strigolactones can aid in the germination and development of the weed.

vovikov84 [265]
Hello. The graphics related to this question were not included, making it impossible to address your inquiry. However, I've created a model chart that illustrates the situation described in the question and is attached below. In the chart, it becomes apparent that as more students attend character education classes, their acts of foolishness increase.

Anna [191]

Answer:

The friction force is what counteracts the movement of the block as it slides down the ramp.

Explanation:

When a forward force is applied, the block moves horizontally along the ramp or floor. The force opposing this movement is known as friction. When stationary, static friction acts on the block preventing movement, but once the block starts moving, static friction is replaced by kinetic friction, which resists the block’s motion and slows it down.
