Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.

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.

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.

Why is a feather non living? Give detailed explanation. Thanks
Answers
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

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.

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.
