Answer:
Option A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.

Can any any one help?
Answer:
x=-5
Explanation:
2/3x-1/2=1/3+5/6
Two thirds x is equal to four sixths x.
4/6x-1/2=1/3+5/6x
Subtract 4/6x from both sides.
-1/2=1/3+1/6x
Make sure -1/2 and 1/3 have a common denominator before subtracting 1/3 from both sides.
-3/6=1/3+1/6x
-5/6=1/6x
Multiply both sides by six to get x.
x=-5
How does coral reef damage negatively affect the land? a.) There is more biodiversity. b.) There is a loss of cures. c.) There is more land erosion.
Coral reef damage negatively affects the land primarily by causing a loss of cures. Hence the correct option is B.
1. Loss of cures: Coral reefs are incredibly diverse ecosystems that provide numerous ecological and economic benefits. One significant impact of coral reef damage is the loss of potential cures and medicinal resources. Many marine organisms, including those found in coral reefs, contain bioactive compounds that have the potential for developing new medicines, treatments, and therapies. By damaging coral reefs, we risk losing these valuable resources and potential cures for various diseases.
2. Biodiversity decline: While option A, "There is more biodiversity," is incorrect in this case, it is important to note that coral reefs are known as the "rainforests of the sea" due to their high biodiversity. Coral reefs support a wide range of marine species, providing habitats, shelter, and food sources. When coral reefs are damaged, either through human activities like pollution, overfishing, or climate change-related factors like coral bleaching, the biodiversity of the reef ecosystem decreases.
3. Land erosion: Option C, "There is more land erosion," is not typically a direct consequence of coral reef damage. However, healthy coral reefs do play a role in protecting the coastline from erosion. Coral reefs act as natural barriers that help dissipate the energy of waves, reducing wave-induced erosion and protecting nearby coastlines from storms and wave action. When coral reefs are damaged or destroyed, the protective function of the reef is lost, potentially leading to increased erosion of the nearby land.
Hence the correct option is B

What is one of the reasons why Gregor Mendel chose to study pea plants? They exhibit only a single trait. They produce flowers. They grow very slowly. They reproduce sexually.
Answer:
They reproduce sexually.
Explanation:
They exhibit multiple traits and grow quickly.
One of the reasons why Gregor Mendel chose to study pea plants is because they reproduce se-x-ually
Gregor Mendel's study of pea plantIn Gregor Mendel's work on pea plants, he discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Parental genes are randomly separated to the reproductive cells so that s-ex cells contain only one gene of the pair

Answer:
1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the entire year, and this explains its warm climate.
2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.
3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.
4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

juan earn $11 per hour and works at most 30 hours per week. identify the independent and dependent quantity in the situation, and find reasonable domain and range values
Answer:
The hours are the independent variable.The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .The domain is 0 to 30 The range is 0 to 330Explanation:
The hours are the independent variable and should be plotted on the x-axis .
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
---------------
Let +W+ = wages/wk earned
Let +h+ = hours/wk worked
The equation is:
+W+=+11h+
The domain is 0 to 30
( no hrs worked to 30 hrs worked )
The range is 0 to 330
( no wages eared to +11%2A30+=+330+ earned )
Microorganisms of a family of fungi, called the Lepiotaceae, live with leaf-cutter ants. The ants collect fresh leaves to grow the
fungus, and then they feed the fungus to their larvae. Another type of microorganism, a fungus of the Ophiocordyceps family, also
has a relationship with a type of ant. The spores of the fungus attaches to carpenter ants in order to complete its life cycle. The
spores spread into the ant's body and causes behavioral changes in the ant, eventually causing the ant's death.
What does this information demonstrate?
Answer:
Between the Lepiotaceael and the eaf-cutter ants, there is what we call mutualism. They both depend on each other buh no harm is done.
But between Ophiocordyceps family and the carpenter ants, it is called parasitic relationship. The Ophiocordyceps harms the carpenter ants.

Which is not a benefit of maintaining sustainable forest ecosystems?
Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds
The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.
An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds, provision of habitats for other species, and playing important roles in the stability of climates.Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.
The only option that is not a benefit of maintaining sustainable forest ecosystems is A.
