Answer:
A. is repeated many times to ensure that the results are accurate
Explanation:
A controlled experiment is repeated many times to ensure that the results are accurate
Answer:
The correct answer is letter D. Conventional breeding
Explanation:
In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.
Answer: I included a labeled graph of both a plant cell and an animal cell. I don't know if you needed an explanation of what they do, too, but I'll include it anyway.
Explanation:
The Cell Membrane, or plasma membrane, provides protection for the cell. It also transports substances in and out of the cell.
The Cell Wall (only plants) provides the structure for a plant, as well as added protection.
The Mitochondria are the powerhouse of the cell, providing energy for our cells to do their work. They produce a small molecule called ATP (adenosine triphosphate), where the energy is stored and sent to where it is needed.
The Lysosomes are the waste facilities of cells. They breakdown excess or worn-out cell parts, destroy foreign or invading bacteria, and digest macromolecules (carbs, lipids, proteins, and nucleic acids)
