____________ is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber.There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential.Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the ____________ potential that excites the muscle fiber.The process begins with a nerve signal stimulating a voltage-gated ____________ ion channel to open, allowing the ions to enter the axon terminal.The ions stimulate the release of ____________ into the synaptic cleft.
Answer:
Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.
2. When two species compete for the same
resource, they sometimes divide this
resource. This is an example of
a. niche partitioning
b. niche equivalency
c. evolutionary response.
d. ecological equivalence
Answer:
a
Explanation:
When two species compete for the same resource, they sometimes divide this resource. This is an example of niche partitioning. Hence, the correct option is A.
What is niche partitioning?Niche partitioning refers to the process by which different species divide up available resources in an ecosystem, such as food, habitat, or mates. This division of resources reduces competition between species and allows them to coexist in the same ecosystem.
It can also occur in terms of behavior or timing of an activity. In general, it helps to reduce competition between species, allowing them to coexist and thrive in the same ecosystem. For example, same species of bats hunting on same type of insects will hunt in the different time of the day to reduce competition.
This allows for greater biodiversity and stability in an ecosystem. Hence, the correct option is A.

Lichens that colonize bare rocks are an example of a pioneer
species. In which environment would a pioneer species of lichen
be most successful?
Select one:
A:a grassland that has established itself on the site of an old farm
B:an old growth deciduous forest
C:a hillside that has been cleared by a volcanic eruption
D:a mountain meadow after a thunderstorm
Answer:
C. A hillside that has been cleared by a volcanic eruption.
Explanation:
Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire or other natural disasters. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.

One of the four fundamental interactions in nature is? Electromagnetism Gravity Strong interaction All of the above
Answer:
The correct answer is All of the above. In nature there are four forces, (also called interactions or fields in Physics) that are responsible for all phenomena in the universe: the gravitational force or interaction, the strong interaction, the electromagnetic and the weak nuclear.
Explanation:
The fundamental interactions or forces that describe all the interactions between the constituents of matter are each of the interactions that matter can undergo and that cannot be decomposed into more basic interactions. There are four basic forces that describe all interactions: Gravitational, that is responsible for the interaction between particles with mass and, by extension, for the configuration on a macroscopic scale of the Universe and its stability. Electromagnetic, is responsible for the interaction between electrically charged particles and, by extension, for all Chemical reactions, Weak is responsible for the disintegration of certain unstable particles; that is, of those processes in which some particles decompose (decay) into lighter ones and Strong interaction is the most complicated interaction to describe due to its different behaviors at different action distances; by means of which a global vision of the to physics without breaking it down.
Look at the diagram of a euglena cell. Early scientists were not sure how to classify this organism.
What is one reason that it might be difficult to classify euglena?
Answer:
Since Euglena have features of both animals and plants, early taxonomists, working within the old two-kingdom system of biological classification, found them difficult to classify - not because they had features different from an animal and different from a plant, but because they had some features that were animal-like and some features that were plant-like.

How will antibiotic resistance affect human populations if no action is taken by our healthcare system?
Answer:
Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality

How does ADH work to balance water in the bloodstream and urine??
Answer:
The kidneys can adjust the concentration of the urine to reflect the body’s water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.

How do gravity and inertia work together in our solar system?
Answer:
They work together to keep things in orbit.
Explanation:
Gravity pulls things in, while inertia says that all celestial objects will try their best to continue forward. The results in the orbiting of celestial objects, like the Earth, around other celestial objects, like the Sun.
Answer:
The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.(Source: sciencing.com)

On a warm day near the ocean, a breeze or wind often blows from the water to the land. Explain why this happens
Answer:
It occurs because of the difference in temperature between the ocean and the land.
This happens because the land heats up faster than the water, causing the air to rise above the land and allowing cooler air from the ocean to move in and take its place.
What is sea breeze?Because land and water have different capacities for holding heat, the land will heat up more quickly than the water on a hot day near the ocean. As a direct consequence of this, the air that floats above land tends to become warmer and less dense than the air that floats above water. Because of this, a region of low pressure is created over the land, while a region of high pressure is created over the water. In order to maintain a natural equilibrium, air will always move from areas of higher pressure to areas of lower pressure.
A breeze or wind that blows from the water to the land is caused by the air that is cooler and denser over the water moving towards the air that is warmer and less dense over the land. This phenomenon, which is referred to as a sea breeze, can assist in moderating temperatures on land, thereby making it feel more bearable and pleasant to be there.

Bacteria convert the nitrogen in the atmosphere into
a.Usable nitrogen
b.Non-usable nitrogen
Answer:
b. Usable nitrogen
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
