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.

Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
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.

Are stars able to adapt to their environment? ANS can stars in the space respond to their changes and reproduce? Pls HELP. NEED FOR BIO

Answers

Answer:

Yes. Stars can adapt to their environment. And yes, stars can reproduce when the environment changes.

Explanation:

Answer: Stars are not living organisms. They do not reproduce. In a way, they are their own environment.

Explanation: Living organisms are made of the same "stuff" as the stars, and we depend on our star, the Sun, for energy. But the Sun can not reproduce another sun. It doesn't adapt. Forces of gravity within the galaxy and in the universe determine where stars travel, and their mass and temperature determine how long they will keep shining.

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.

Which of the following are factors that limit enzyme activity?

denaturation

increase in substrate

optimal temperature

increase in number of enzymes

Answers

According to the research, increase in substrate and temperature are factors that limit enzyme activity.

What are enzymes?

It is a protein that catalyzes the biochemical reactions of metabolism and acts on molecules known as substrates.

The way that the enzyme has to carry out its catalytic activity will be in the first place to bind with the substrate, this is limited by different factors such as the concentration of the substrate and the temperature.

Therefore, we can conclude that according to the research, increase in substrate and temperature are factors that limit enzyme activity.
