Write a short note on oxygen gas
Answer:
alr
Explanation:
Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere

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
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.

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

Describe the relationship between a tree and a cow. (Use terms like oxygen, carbon dioxide, photosynthesis, and cellular respiration)
Answer:
Without the tree the cow couldn't live.
Explanation
The cow breathes in oxygen and breathes out carbon dioxide. The tree uses cellular respiration and photosynthesis in order to take carbon dioxide (which the cow produces) and make it into oxygen (which the cow needs to breaths).
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
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.

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?
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.
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?
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.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature.

Why is a feather non living? Give detailed explanation. Thanks
Answer:
feathers are dead tissues. They are only alive while developing as they have a blood supply. Feathers are produced by living cells located in small pit-like follicles in a bird's epidermis, its outer skin layer. The feather is enlarged by the keratin that is protruding straight out from the skin follicle. In order for something to be classified as anything that was never alive
