As biotechnology has improved, scientists are able to look more closely at dna, the molecules that hold genetic instructions for development, reproduction, and functioning. the ability to study dna closely allows scientists to find evidence of genetic mutation and better understand the effects of these changes. think about how genetic mutations can be harmful, beneficial, or cause no change at all.
answer choices:
-a mutation in the hemoglobin gene can result in sickle cell anemia.
-a mutation that could cause a genetic disorder gets repaired by enzymes before an altered protein is produced.
-over time, a population of green lizards that live in a desert with white sand become much lighter in color.
-a mutation of a protein results result in protection against a destructive bacteria.
-a mutation occurs in a non-coding portion of dna and does not change the amino acid sequence of a protein.
-an extra copy of a human chromosome results in a child born with down's syndrome.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
