How do mycorrhizae influence plants?
Answer:
Mycorrhizae are a symbiotic association between plant roots and fungi. By differentially altering the performance of individual species within the community, mycorrhizae can influence plant community composition, enhance competition, and create synergism through the sharing of resources between species.
Explanation:
In a salt marsh in Georgia, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. Calculate the efficiency of photosynthesis.?
Answer:
[tex]\mathtt{The \ efficiency \ of \ photosynthesis =1.08 \%}[/tex]
Explanation:
Given that:
the quantity of solar radiation = 7,000,000cal/m²/day
The producers' gross productivity in the salt marsh (mostly microscopic algae) is 0.0040 g/cm²/day.
= 0.004 × 2920 cal × 10000 m²/ day
= 116800 cal/m²/day
The respiration requirement is 35% of the gross primary productivity.
i.e 35% of 116800 calories/m²/day
=[tex]\dfrac{ 35}{ 100 }\times 116800[/tex] calories/m²/day
= 40880 calories/m²/day
The Net primary productivity NPP = Gross productivity - Respiration requirement
=( 116800 - 40880) calories/m²/day
= 75920 calories/m²/day
We can calculate the efficiency of photosynthesis by using the formula:
[tex]\mathtt{The \ efficiency \ of \ photosynthesis = \dfrac{ Net \ primary \ productivity \ NPP}{quantity \ of \ solar \ radation} \times 100\%}[/tex]
[tex]\mathtt{The \ efficiency \ of \ photosynthesis = \dfrac{ 75920 \ cal/m^2/day}{7000000 \ cal/m^2/day} \times 100\%}[/tex]
[tex]\mathtt{The \ efficiency \ of \ photosynthesis =1.08 \%}[/tex]
It has become rather easy for people to have access to and use of a debit card. How does a person avoid unnecessary fees that can be associated with getting money from the checking account that is attached to the card?
A) Only using the ATMs that are located at convenience stores.
B) Pull out more money than you need every time you use the card.
C) Only using the ATMs that are associated with the bank account.
D) Only using ATMs that have the same symbols on the machine as on the card.
Answer:
C
Explanation:
Only use the ATM that is associated with the bank account. Most banks do not charge a fee to use their ATMs. Some stores and other ATMs charge a fee to pull out extra money or to use their machines. The symbols on the cards just represent the system that the card uses, not fees associated with the card.
We are required to find a way in which a person can avoid unnecessary fees that can be associated with getting money from the checking account that is attached to the card.
The way in which way in which a person can avoid unnecessary fees that can be associated with getting money from the checking account that is attached to the card is "Only using the ATMs that are associated with the bank account".
Debit cards are issued by the bank to an account holder in order to make withdrawal and make payment.When making payments or withdrawal from a bank not associated with your bank, you will be charged some unnecessary fees. This could be avoided by making transactions in the bank associated with your debit card.Therefore, the way in which way in which a person can avoid unnecessary fees that can be associated with getting money from the checking account that is attached to the card is "Only using the ATMs that are associated with the bank account".Read more:

Why are theories and hypothesis important in pcychology? Why do we need replicate studies that have been conducted?
Answer:
A theory is more than simply an idea because the idea itself forms the hypothesis that in turn is used as the context for the experiments, tests, and gathering evidence that will go to prove or disprove the initial hypothesis. A theory then is the positive benefits of proof and evidence and is the proven outcome of the subject of the hypothesis.

We want to solve. Be sure to follow PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
First, multiply 2 and 5 inside the parentheses.
4(8+ (2*5) -6)
⇒ 2*5=10
4(8+10-6)
Next, add 8 and 10.
4( (8+10) -6 )
⇒8+10=18
4(18-6)
Next, subtract 6 from 18.
⇒18-6=12
4(12)
Finally, multiply 4 and 12

Explanation:
Kelly has driven by Ryan's house 3 times a day for the past 6 weeks. Every time she
drives by, she leaves 2 love letters on his porch. Ryan has thrown out 90% of the
letters and a dog ran away with 5% of them. Ryan secretly keeps the rest in his
Memories Box. How many letters does he have in his box?
Answer:
There are 13 letters in his box
Explanation:
Given
Duration = 6 weeks
Letters = 2 per trip
Required
Determine the number of letters with Ryan
First, we need to calculate the duration in days
Duration = 6 weeks
Duration = 6 * 7 days
Duration = 42 days
Next, we need to determine the number of trips
Trips = 3 times a day
So: In 42 days, the trip will be
Trip = 3 * 42
Trip = 126
Next, we need to calculate the number of letters delivered
Letters = 2 per trip
So: In 126 trips, the letters will be
Letters = 2 * 126
Letters = 252
At this point, we can now calculate the number of letters in his memory box.
First, we need to determine the percentage left with him
%Left = 100% - %Thrown Away - %Snatch by Dogs
%Left = 100% - 90% - 5%
%Left = 5%
The number of letters left is:
Numbers = %Left * Letters
Numbers = 5% * 252
Numbers = 12.6
Numbers = 13 (Approximated)
Hence, there are 13 letters in his box
which statement is an example of a smart, healthy choice
Answer:
An example of a smart and healthy choice is to replace a breakfast consisting of sweets, coffee with sugar, and white bread with jams with a much leaner breakfast consisting of coffee with sweetener, fruits, and ham and cheese omelet.
In this way, a meal high in glucose, fats and simple carbohydrates, which together tend to make the person fat and increase cholesterol, would be replaced by a much leaner diet, without added sugars, with seasonal fruits and protein, which together provide the necessary nutrients to start the day with energy and a healthy and balanced diet.

Suppose a fox in a food web feeds only on rabbits, squirrels, mice and birds, all of which feed exclusively on plant material. Assuming that a fox’s daily caloric requirement is 800 kcal, and that only 10 percent of the energy at one trophic level can be passed to the next trophic level. How many square meters of plant material are required to support the fox, if the net primary productivity of the plant material is 8,000 kcal/m2/yr? Hint: draw the food chain to determine how many kcal/m2/yr the fox receives to determine how much land he needs and remember the 10% rule!
Answer:
square metres of plant materials required to support the fox = 3650 m²
Explanation:
From the given information:
the daily caloric requirement of the fox = 800
In a year, we have = 800 kcal × 365 /year = 292,000 kcal/year
Also, only 10% of the energy at a particular trophic level can be passed onto the next.
the net productivity of the plant material = 8000 kcal/m²/yr
So, using 10% of energy at a particular level, the fox only need 80 kcal/m²/yr
The objective is to determine in square meters, how many materials are required to support the fox.
square metres of plant materials required to support the fox = [tex]\dfrac{292,000}{80}[/tex]
= 3650 m²
Can you think of another example in history where an empire was broken into smaller chunks like the Khanates of the Mongol Empire?
Answer:
Another historical example in which a great empire was dissolved between several territorial entities of much smaller size and hierarchy is that of the Western Roman Empire, which controlled most of the European territory until its dissolution in the year 476, when its domains were divided between various kingdoms and minor entities as a consequence of the conquest of Rome by the barbarians.
After the dissolution of the Roman Empire, Europe began a period of feudalism, where feudal lords controlled small territories within larger kingdoms, holding royal power and forming their own armies. Thus, for example, within the kingdom of the Visigoths, formed after 476, several strong men were vying for power, in turn controlling smaller regions of the kingdom.
Western Roman Empire, which controlled most of the European territory until its diussloution, when its domains were divided between various kingdoms as a consequence of the conquest of Rome by the mongols.

Which of the following are benefits of well-named variables? Select two answers.
Options:
(a) The program will be easier to read.
(b) The program will run faster.
(c) The program will be easier for others to debug.
(d) The program will use less resources.
Answer:
(a) The program will be easier to read.
(c) The program will be easier for others to debug.
Explanation:
Naming variables properly is an essential thing to do when writing programs or even developing software applications. This involves making use of descriptive and logical names when declaring variables.
For example, to store the age (say 67) of a user in a variable, the following ways are possible:
i. $x = 67
ii. $name = 67
iii. $age = 67
From (i), simply using $x = 67 does not exactly tell that 67 is the age of some user. That makes it a bit difficult to understand the code.
Also, from (ii), using $name = 67 is quite misleading. The variable name $name already depicts that the variable should store the name of some sort. However, a number is supplied. This is not a good way of naming variables.
The third option, from (iii), however clearly depicts the intention of the line of code without having to think too much. This is a well-named variable.
In general, well-named variables;
(i) makes it pretty easy to read and thus understand the lines of code in a program
(ii) following from (i), makes it easier for other programmers to be able to debug such program.
Well-named variables however have nothing to do with the speed of the execution of the program neither do they have anything to do with the amount of resources that will be used by the program.

How is a combining of cultures reflected in the song excerpt?
The song was sung in English in the colonies.
O The Yoruba people were American Indians native to Brazil.
O The slaves of Brazil replaced their traditions with Christianity.
The words reflect both Christian and traditional African beliefs.
Answer: The words reflect both Christian and traditional African beliefs.
Explanation:
The Yoruba are a major tribe in Africa with a special focus in Nigeria. Quite a number of enslaved peoples came from the Yoruba tribe which led to them exporting their culture to the Americas.
In the song above, the Yoruba sing of the god Obatala who created the Earth by creating land on the water beneath the sky and creating humans. This mirrors Christian creation stories as God created the Earth and Humans. The song also speaks of the kindness of the seventh day of creation which in Christianity was the day God rested after creation.
Song also alludes to Obatala being the father and also the savior and Christians believe that God is the Father as well as the son, Jesus who was the savior.
The words therefore reflect both Christian and traditional African beliefs.

What term describes the moon's path around Earth?
eclipse
phase
revolution
rotation
Answer: C - revolution
Explanation:
The term that describes the moon's path around Earth is revolution. The correct option is C.
What is moon's revolution?The Moon revolves around the Earth in a circular motion known as revolution.
This is analogous to the Earth's revolution around the Sun. The path that the Moon takes to orbit the Earth is referred to as its orbit. The Moon takes about 27 days to complete one orbit around the Earth.
Because of the Moon's 27-day orbit around the Earth, the times of high and low tides change. The Sun also plays a role. The Sun's influence on tides is roughly half that of the Moon's.
The moon does not appear to be spinning and appears to be almost perfectly still to observers on Earth. This is referred to as synchronous rotation by scientists.
Thus, the correct option is C.

What was the primary reason that William Penn granted religious freedom in his colony?
O To antagonize the Puritan New England colonies in response to their disdain of the Quaker religion
To encourage settlers to come to his colony
To provide a haven for all religions being persecuted Europe
To foster peaceful coexistence with the Native American population in Pennsylvania
Answer: To encourage settlers to come to his colony
Explanation:
The colony of Pennsylvania was founded by William Penn on land given to him by the King of England to settle a debt that the King had owed to Penn's father. The King then named the colony after Penn's father.
William had asked for the land in order to allow him set up a colony where the Quakers (himself a Quaker as well), could attain religious freedom and be free from persecution.
In order to get more people to settle in the colony, William allowed for religious freedom at a time where the other colonies were still dragging their feet about it. This led to many people settling in Pennsylvania like William wanted.
