How does matter change from one state to another?

Answers

Matter changes state when energy is added or taken away. When matter is heated enough, the molecules move faster and with greater energy. ... If enough heat is added, a solid can become liquid and a liquid can become gas.

As energy is passed through the food chain, some of the energy is lost as heat. What is the approximate amount of energy that is passed from one trophic level to the next?
(1 point)
O 50 percent
O 15 percent
O 75 percent
10 percent

Answers

10 percent of energy is passed from one tropic level to the next. While the other 90 percent of energy is lost to heat.

Concerns about soil management are not the same in all climates. Suppose you own a farm in the state of Washington, where there is a lot of rain throughout the year. Which two issues would be of major concern in managing the soil on your farm?

Answers

Answer:

Soil Erosion

With so much rain coming all year, soil erosion will definitely be a problem if not handled. The splashing of the water on the soil and the subsequent runoff will increase soil erosion. Your farm will lose soil if this is not stemmed and losing soil can lead to a number of negative consequences.

Loss of Nutrients.

One such effect of soil erosion which will be another major concern is the loss of nutrients. This happens when the structure of the soil is broken down by the erosion and the various nutrients in the soil will be carried off as the rain moves away and lost to your farm.

Differentiate between the three dose-response curves, and explain why these curves do not apply to individuals.

Answers

Answer:

LD-50: lethal dose 50%, dosage that causes death to 50% of the exposed population

ED-50: effective dose 50%, dosage that causes an effect in 50% of the observed subjects

TD-50: toxic dose 50%, dosage that is toxic to 50% of the observed subjects

These curves do not apply to individuals because it is hard to predict the dosage that will cause a response in an individual, and more practical to predict what percentage of a population will be affected by a certain dosage of a chemical.

experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?

Answers

Explanation:

the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you .

When the pH is raised from 2 to 11 the most likely effect on the reaction is ;  

The rate of reaction will decrease/delayed

Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.

Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.

Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

The graph models the linear relationship between the water level of the river in feet and number of days the water level measured. Which function can be used to find y, the water level of the river after x days

Answers

Answer:

option 4, y=1/4x+16

Explanation:

to solve this you must find the slope and the y intercept.

slope is rise/run, and equal to 2/8 or 1/4

then, the find the y intercept, find where the line crosses the y axis. Here it is 16.

finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.

after you plug in your answers you are left with y=1/4x+16.

Diversity among members of a species is important because diversity increases the chances of survival under changing conditions.

If a disease spreads throughout a species, the species with genetic diversity will survive. If the species does not have genetic diversity, they will be wiped out by the disease.

A because the more genetic diversity a species had, the more likely they are to have characteristics that are needed to survive. Plz vote brainliest

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph

Answers

Answer: definitely C will help you

Explanation:

Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

What is the main reason of emission of carbon?

According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.

According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.

This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.

These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
