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
Answers
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
Answers
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.

Answers
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.
The world's atmosphere can hold more moisture as it warms. As a result, the overall number of heavy storms has likely increased since midcentury due to global warming. True or false?
Answers
Answer:
True.
Explanation:
Yes, the number of heavy storms has increased due to global warming because of the holding power of moisture by the atmosphere due to higher temperature. When the air is warmed, the air can hold more water at that temperature so due to more holding power of moisture by the air the number of storms increases. One NASA study supports that global warming is causing the increase in number of extreme storms especially in the tropical ocean.

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
Answers
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.

In the disease myasthenia gravis, the human body makes-by mistake- antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to devastating progressive weakening of the muscles of people affected. Early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. Eventually, impaired breathing can cause death. Explain which step of muscle function is affected
Answers
Answer:
Muscle contraction function.
Explanation:
The nerve endings possess synaptic acetylcholine vesicles ready to be released. The action potential depolarizes the presynaptic terminal and increases the concentration of axoplasmic calcium; Acetylcholine molecules are thus released, so that the concentration of the neurotransmitter at postsynaptic (nicotinic) receptors is temporarily increased. This is followed by post-synaptic membrane depolarization, muscle membrane action potential with increased rnioplasmic calcium concentration, and finally muscle contraction. Acetylcholine is hydrolyzed by acetylcholinesterase and resynaptic at the presynaptic level by cholinecetyltransferase. The etiopathogenesis of myasthenia gravis is autoimmune and there are antibodies against acetylcholine receptors that circulate in the blood, as well as a decrease in the number of receptors on the motor plates, that is, it is produced by the postsynaptic blockage of the myoneural plaque, that generates fatigue and localized or generalized muscle weakness that is characterized by the worsening of the contractile force of the muscle.

How do gravity and inertia work together in our solar system?
Answers
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)
