Answer:
Most of us have some familiarity with everyday magnetic objects and recognize that there can be forces between them. We understand that magnets have two poles and that depending on the orientation of two magnets there can be attraction (opposite poles) or repulsion (similar poles). We recognize that there is some region extending around a magnet where this happens. The magnetic field describes this region.
There are two different ways that a magnetic field is typically illustrated:
The magnetic field is described mathematically as a vector field. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force. Arranging many small compasses in a grid pattern and placing the grid in a magnetic field illustrates this technique. The only difference here is that a compass doesn't indicate the strength of a field.

<span>NA contains only elements, so it does not react easily. Many organisms do not contain DNA. Certain mutations in DNA happen at a constant rate. DNA does not change over time, making it a valuable clue.</span>
Answer: A - Uptake of food and water by plants
The xylem vessels in the roots of the plants use the mechanism of capillary action and work against gravity to pull water molecules and nutrients from the soil and carry them upwards to the leaves of the plant to provide nourishment to the plant.
The genotypes of its gametes would be TS, tS, Ts, and St. This would mean the answer would be C. Hopefully this helps you.
