Answers

Answer and Explanation:

We can mention the advantages of the plants of the Fabaceae family, also known as legumes, such as beans, soybeans, peanuts and peas. First, we must mention how these plants have high nutritional values ​​providing high levels of iron and nitrogen that are essential elements for human health. However, a benefit that these planats produce and that is important on a worldwide scale is the fixation of nitrogen in the soil. All living beings need nitrogen in their bodies, since nitrogen is a primary element in the composition of nucleic acids and proteins. Animals are able to ingest nitrogen from the vegetable diet, but vegetables cannot absorb nitrogen from the atmosphere or nitrogen from the soil, because they are not in molecular forms that plants can absorb. To reverse this, farmers put chemical fertilizers on the plantations, but these fertilizers pollute the environment intensely. It is in this scenario that the plants of the Fabaceae family are important. This is because these plants are able to associate with bacteria that can capture atmospheric nitrogen and place it in the soil, in the molecular form that all plants can absorb. This allows plants to have the necessary nutrients for their growth, reduces environmental pollution, decreases spending on agricultural production, promotes correct levels of nitrogen for human consumption and allows agricultural products to be healthier.

Explanation:

These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.

Answers

Answer:

1) A mutation appeared in one weed plant that made that weed not   susceptible to the herbicide ( B )

2) The weed will survive long enough to reproduce ( B )

Explanation:

1) The most likely reason the weed remained is :  A mutation appeared in one weed plant that made that weed not susceptible to the herbicide

The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now

2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce

The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation

The ability to taste PTC comes from the presence of a dominant allele (T). A population of 20 individuals was surveyed to determine whether or not they could taste PTC. Sixteen out of the twenty surveyed could taste PTC. Four could not taste PTC. Assume that Hardy-Weinberg Equilibrium conditions are met in the population. Round all answers properly to 2 decimal digits. Rounding rules: When rounding to 2 decimal digits, look at the third decimal digit. If the third digit is 5 or greater, round up. If the third digit is less than 5, round down.

If the habitat does not change there should be no

Answers

The Correct answer Is B.

this is because of natural selection

hope this helps !

The lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease due to industrial melanism. Therefore, option B is correct.

What is industrial melanism?

Industrial melanism is a phenomenon in which the frequency of dark-colored or melanistic individuals in a population of organisms increases as a result of environmental pollution.

This phenomenon was first observed in the 19th century in industrialized regions of England, where the population of peppered moths shifted from mostly light-colored to mostly dark-colored in response to pollution from industrial activities.

Thus, the lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease. Therefore, option B is correct.
