Answer:
plants need protein for healthy growth and development. One of the critical roles of protein in plants is regulating phototropism and mediating the response of plants to light-dark cycles. Proteins are also involved in energy-generating reactions, intracellular structure and membrane transport.
Explanation:
Answer:
I would have to say recharge of the aquifer by using ground water after some precipitation.
Explanation:
Melting snow or rain increases ground water that percolates down to replenish the aquifer.
Elevation changes causes the aquifer to flow up in low spots/springs on the surface. And the cycle repeats through evaporation and plant respiration.
Answer: 47 Chromosomes
Explanation: People with Down syndrome typically have three copies of chromosome 21 in each cell, for a total of 47 chromosomes per cell.
There would be less variability in the genes of the watermelon plants and is denoted as option A.

This is defined as the difference between organisms which is caused by genetic or environmental factors.
Using the seeds from the largest, tastiest watermelons will reduce variability over time because these characteristics will become dominant.
