Complete question:
In a population of toads, the average body length is 30mm. Body length is variable and the narrow sense heritability for body length is 0.1 for this population. You cross a male of 20mm with a female of 22mm. In order to determine the expected average offspring length, what do you multiply with your heritability?
30mm 9mm 0.1 8mm -9mm -0,5Answer:
The correct option is -9mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).
Explanation:
Available data:
the average body length, ABL, is 30mmthe narrow-sense heritability, h², for body length is 0.1male of 20mmfemale of 22mmTo answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.
We can get the selection differential, SD, by getting the difference between the mean value of a population length, ABL, and the mean value of the parents of the next generation, PABL. So, in this example the selection differential is:SD = (20mm + 22mm)/2 - 30mm
SD = 21 mm - 30mm
SD = - 9mm
The heritability in the narrow sense, h², for body length in the population ish² = body lengths of the offspring average/selection differential
But we already know the value of h². And we want to know the body length of the offspring. So we just need to clear the following equation.
OABL = ABDL + h² ( PABL - ABL)
where,
offspring average body lengths = OABLpopulation average body length = ABL = 30mmparents average body length = PABL = 22mmSelection diferential = SD = -9mmnarrow sense heritability = h² = 0.1OABL = ABDL + h² ( PABL - ABL)
OABL = ABDL + h² ( SD)
OABL = 30mm + 0.1 ( -9mm)
OABL = 30mm + (-0.9 mm)
OABL = 21 mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).

Explain the difference between renewable and nonrenewable resources and give an example of each.
Answer:
Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.
Explanation:
If something is Nonrenewable; for example fossil fuels like coal, oil, and natural gas, then that means that the organic matter is limited and not going to grow or be created easily on Earth.
Renewable Resources are usually classified into five categories; Hydro, Solar, Wind, Biomass, and Geothermal. All of these resources are easily accesible and can be used as a natural energy source.

Jacky leaves the office at 4:15 PM. If
she reaches her house at 4:55 PM
when her house is 25 km away from
her office, approximately, how fast did
she drive?
Given:
Jacky leaves the office at 4:15 PM and she reaches her house at 4:55 PM.
Distance between office and her house = 25 km
To find:
The driving speed of Jacky.
Solution:
The difference between 4:15 PM and 4:55 PM is 40 minutes.
60 minute = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
40 minute = [tex]\dfrac{40}{60}[/tex] hour
= [tex]\dfrac{2}{3}[/tex] hour
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]Speed=\dfrac{25}{\dfrac{2}{3}}[/tex]
[tex]Speed=\dfrac{3\times 25}{2}[/tex]
[tex]Speed=\dfrac{75}{2}[/tex]
[tex]Speed=37.5[/tex]
Therefore, the driving speed of Jacky is 37.5 km per hour.

A tugboat tows ships out of a harbor. The tugboat starts pulling the ships when they are stopped at a dock.
Masses of ships
Name Mass (kg)
Eden 3,239
Skipjack 2,273
Standard 2,020
Thunderer 2,526
Viceroy 1,859
The tugboat tows with the same force no matter the size of the ship. Order the names of the ships to show the size of the acceleration each ship will have as it starts to move.
Answer:
In order of decreasing acceleration experienced by each ship, the names of the ships are as follows:
Viceroy
Standard
Skipjack
Thunderer
Eden
Explanation:
A force is a push or pull upon an object resulting from the object's interaction with another object.
According to Newton's second law of motion, the acceleration of an object is directly proportional to the resultant (or net) force and inversely proportional to the mass of the object and the acceleration occurs in the same direction as the force.
Mathematically, a = F/m
From the given question, the tugboat tows the ships with the same force no matter the size of the ship, therefore, force is constant. The acceleration each ship will have as it starts to move assuming force = 1 N, is given below:
Eden; mass = 3,239;
acceleration = 1/3239 = 3.09 * 10⁻⁴ m/s²
Skipjack 2,273
acceleration = 1/2273 = 4.40 * 10⁻⁴ m/s²
Standard 2,020
acceleration = 1/2020 = 4.95 * 10⁻⁴ m/s²
Thunderer 2,526
acceleration = 1/526 = 3.96 * 10⁻⁴ m/s²
Viceroy 1,859
acceleration = 1/1859 = 5.38 * 10⁻⁴ m/s²
Thus, in order of decreasing acceleration experienced by each ship, the names of the ships are as follows:
Viceroy
Standard
Skipjack
Thunderer
