Answer:
Sunlight provides the energy needed for photosynthesis to take place.
Explanation:
Answer:
The correct option is D.
Explanation: The options attached to this question are given below:
A) Bacteria from other animals replace those killed by the antibiotics.
B) The few surviving bacteria that are affected by the antibiotics develop immunity to the antibiotics, which they pass on to their progeny.
C) The antibiotics cause new mutations to occur in the surviving bacteria, which results in resistance to antibiotics.
D) The antibiotics kill susceptible bacteria, but the few that are naturally resistant live and reproduce, and their progeny repopulate the host animal.
E) The antibiotics persist in soil and water.
Antibiotics are sometimes used in animals to control infections. With time, the microbes that are been targeted with the antibiotics usually develop mutations, which makes the antibiotics to become ineffective, thus, the antibiotics will only be able to kill the susceptible microbes while the ones that have developed resistance will remain and give birth to young ones that are also resistant to antibiotics.
Here is why:
When we solve for the inverse function (see the particular step below; when we have: " y² = x " ;
We take the "square root" of EACH SIDE of the equation; to isolate "y" as a single variable on one side of the equation;
→ √(y²) = √x ;
→ |y| = |√x| ;
y = ± √x ;
Because when we take the square root — or any "even root", for that matter—we have two solutions: of a variable, we have TWO SOLUTIONS: a positive value; and a negative values;
→ since: 1) a "negative value"; multiplied by a "negative value" ; equals a "positive value" ;
→ and as such: a "negative value" ;
multiplied by that same "negative value" ;
{that is: a "negative value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a positive value ;
→ and since:
2) a "postive value"; multiplied by a positive value" ; equals a "positive value" ;
→ and as such: a "positive value" ;
multiplied by that same "positive value" ;
{that is: a "positive value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a "positive value";
→ and since:
3) any given integer, in it "positive value", squared (i.e. raised to the power of "2"); results in a "positive value" ;
→and since:
4) that same aforementioned integer; in its "negative value" form, squared (i.e. raised to the power of "2"); results in that same aforementioned "positive value".

Note the following:

"Given the function: "f(x) = x² " ; Find the "inverse function" .
Let "y" = f(x) " ;
and write as: " f(x) = y = x² " ;
→ " y = x² " ;
→ Now, rewrite the equation; replacing the "y" with "x" ;
and replacing the "x" with "y" ;
→ " x = y² " ;
Now, rewrite the question; isolating "y" as a single variable;
with no coefficient (save for the "implied coefficient of "1" ) ;
→ " x = y² " ;
↔ " y² = x ;
Now, take the square root of EACH SIDE of the equation;
to isolate "y" on one side of the equation;
→ √(y²) = √x ;
→ |y| = |√x| ;
→ y = ± <span>√x .
</span>
Replace the "y" with " f ⁻¹(x)" ; to indicate that this the "inverse function" ;
and write the "inverse function" :
→ " f ⁻¹(x) = ± √x " ;

Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
The answer is A area c alone
