Answer 1
So I believe these are the questions to go with the statement based on the info given to make a question (hypothesis) , I believe it’s “A” because based on the statement it give details about the one of them being able to drink water that contains fluoride salts and the other doesn’t drink water with fluoride salt . And we don’t know where they live , or even who drinks the fluoride salts or no so “A” is a appropriate question to give . And the numerical data part can also include the people who lives in their neighborhoods .

Hope this helps☺️

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

Cost–benefit analysis (CBA), also known as benefit–cost analysis, is rooted in applied welfare economics. It is a way of organizing and analyzing data as an aid to thinking. It provides a set of procedures for comparing benefits and costs and is traditionally associated with government intervention and with the evaluation of government action and government projects. The underlying rationale for CBA is rational choice; that is, a rational agent will weigh the costs and benefits of any proposed activity and will only undertake the activity if the benefits exceed the costs

A)
If the habitat does not change there should be no
change in the moth population.
B)
The lighter moth population will have better chance
of survival due to camouflage. Light moths will
increase: dark moths will decrease.
C)
The population will shift to the to favor the light
moth. The light moth population will increase

D)

foliage growing on the trees. We would predict no
big change in the moth populations, light or dark.

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.

But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO2 and water.
