What is the impact of genetically modified corn on society and environment?

Answers

Answer 1

Answer: Biodiversity Loss: The use of some GM crops can have negative impacts on non-target organisms and on soil and water ecosystems. For example, the expansion of GM herbicide-tolerant corn and soy, which are twinned with herbicides, has destroyed much of the habitat of the monarch butterfly in North America.

A scientist thought he may have discovered a new plant compound that would lower blood pressure in people. In his first experiment, he injected one hundred mice with the compound and found that the blood pressure in ninety-five of the treated mice was not affected. However, all of the mice seemed to grow at a faster rate then the control group. Which statement describes the most likely outcome of this investigation?a. The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug.b. He will develop a second experiment to find a way to make the drug successfully lower blood pressure in mice.c. The data he collected will be used in new investigations to determine why certain people are taller than others.d. He will use these results to conclude that the drug will most likely lower blood pressure in five percent of people.

Which of the following statements is true of linkage?a. The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.b. All of the traits that Mendel studied-seed color, pod shape, flower color, and others-are due to genes linked on the same chromosome.c. Linked genes are found on different chromosomes.d. The observed frequency of recombination of two genes that are far apart from each other has a maximum value of 100%.

Answers

The answer is; The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them

The closer together two genes are on a chromosome, the higher the likelihood that they will be inherited together. This is referred to as genetic linkage. The higher the genetic linkage the lower the recombination frequency of the two genes.

Final answer:

The statement that 'The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them' is true regarding linkage. This is because genes close together are less likely to be separated during crossover in meiosis. Other statements provided about linkage are typically incorrect.

Explanation:

In the context of genetics, linkage refers to the phenomenon where genes that are located nearby each other on the same chromosome tend to be inherited together. Therefore, the correct statement regarding linkage from the provided options is:

The closer two genes are on a chromosome, the lower the probability that a crossover will occur between them.

This is because when genes are close together, they are less likely to be separated during crossover, a process that occurs during meiosis.

Note that not all traits that Mendel studied are due to genes linked on the same chromosome. Most genes are in fact not linked - they can independently assort during meiosis. Equally, linked genes are not found on different chromosomes, they are on the same one.

Lastly, the recombination frequency for two genes that are far apart from each other doesn't have a maximum of 100%. It typically peaks around 50%, which is an indication that the genes behave as if they are independently assorting.

Plants with a primary root and little lateral roots that extend out from it have a ____ system.

Answers

Plants with a primary root and little lateral roots that extend out from it have a tap root system.

A taproot system, generally found in dicotyledons, is made up a central, large pointed root and this is what is called the taproot.

Smaller roots branch off from the taproot and are known as lateral roots. The tap root is larger in diameter than the lateral roots. Tap roots generally grow much more deeply into the soil compared to fibrous roots.

Answer:

The answer is a taproot system.
