Analyze the given diagram of the carbon cycle below.
Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Answer:
F means oxygen from plant goes into the atmosphere.
Explanation:
2. matter is conserved in this process because plants take carbon dioxide from the atmosphere for photosynthesis then produces oxygen into the atmosphere, animals then feed on plants and later the animal's faecal matter is released into the soil and even when animals die, microorganisms in the soil break I down into absorbable form for plants use. which makes matter conserved.
3. mater is in a circular state from atmosphere to plants to animals to soil then absorbed by plants to restart the process again.

What Gegymnosperm is known as a living fossil
Many proteins are regulated by the binding of GTP or GDP. Which form is the active state of the protein
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".

Drought is a weather condition that may limit the amount of water resources available to an ecosystem. Which of the following may be one result of drought?
A. Fish populations may decline due to lower river levels.
B. Birds may not build nests due to temperature change.
C. Flowering plants may produce more seeds due to lack of water.
D. Predator populations may increase due to increased prey populations.
Answer:
A
Explanation:
Droughts generally lower the amount of water in an ecosystem. This also applies to rivers and other such bodies of water, potentially harming or reducing the number of fish.
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

In order to determine the expected average offspring length, what do you multiply with your heritability
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).

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.
Why does rifting might matter to people that aren't geologists? pls help me ASAP this is due in half a hour
Answer:
Rifting is defined as the splitting apart of a single tectonic plate into two or more tectonic plates separated by divergent plate boundaries. The rifting of a continental tectonic plate creates normal fault valleys, small tilted block mountains, and volcanism.
