Answer:
(c)volcanic eruption
Explanation:
An event that may lead to primary succession is volcanic eruption.
Primary succession happens when pioneer organisms colonize an area that holds no life before. It usually happens when a new land is formed or when a bare rock becomes exposed to life.
When volcanic eruption happens, new rocks are formed from the molten magma and these rocks provide a surface that can be colonized by pioneer species such as lichen.
From there, the successional process continues with time until a stable community is formed, all other things being equal.

What will happen to an ecosystem that is experiencing a prolonged drought?
If an ecosystem was experiencing a prolonged drought, there would be a big decrease in the population. All living creatures require water, even the ones well adapted to little water. There probably would be as many planets, for the ones surviving would be ones managing to get water, or ones that can survive off little water. Now on the other hand the animals then wouldn't be getting enough food or water, so then again ones who would manage to survive would be ones adapted to little water and food or are excellent hunters.
You can also expect some animals to leave the ecosystem look for a better source of water and food.
hope this helps to some degree
The diversity, as well as the number of individuals among different species, may decrease gradually due to the scarcity of water.
What is an Ecosystem?An ecosystem may be defined as the place or an area where organisms of different species live together and interact with one another for the purpose of food, shelter, and space.
Every living organism on the earth's surface requires water in order to fulfill its requirement for cellular and metabolic activities.
But if the ecosystem experiences a prolonged drought, the physiology of all living organisms is disturbed due to which they leave the ecosystem, hence the number of species gradually lowers.
Therefore, it is well described above.

How are mean and median alike?how are they different?
Answer:
Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Explanation:
Whole brain death occurs when the ______ ceases to function.
Answer:
Whole brain death occurs when the BRAINSTEM ceases to function.
Explanation:
In the US, whole brain death = legal death. Most people consider that a person is brain dead when the cerebrum, or the higher brain, is dead because the person is not able to think or have control over his/her body, but legally you are brain dead only when the brainstem ceases to function. The brainstem is responsible for keeping you alive and performing the most basic bodily functions like breathing and keeping your heart beating. But once it fails, you are legally dead. Even if your body could still survive using a ventilator and other devices, your brain has ceased to work and you wouldn't be able to survive if you were unplugged.

How does an area's weather differ from the area's climate?
Weather refers to the short-term atmospheric conditions, such as temperature, precipitation, humidity, wind speed, and cloud cover, that occur in a specific area over a short period of time, typically days or weeks.
Climate, on the other hand, refers to the long-term average weather patterns observed in a particular region over a period of decades to centuries.
Weather is the day-to-day variation in atmospheric conditions, including temperature, humidity, precipitation, wind speed, and cloud cover. It describes the current state of the atmosphere at a specific location and can change rapidly. For example, one day may be hot and sunny, while the next day may be cloudy and rainy. Weather conditions are influenced by various factors, such as air pressure systems, temperature gradients, and local geography.
Climate, on the other hand, represents the average weather patterns and conditions observed in a region over a long period of time. It is determined by factors such as latitude, elevation, ocean currents, and prevailing winds. Climate provides a broader perspective and encompasses the typical range of weather conditions experienced in a particular area. It takes into account long-term trends, seasonal variations, and averages of weather parameters.
While weather can change from day to day or even hour to hour, climate reflects the long-term patterns and trends in weather. For example, a region with consistently high temperatures and low rainfall throughout the year would have a hot and arid climate, regardless of occasional variations in daily weather conditions.
In summary, weather describes short-term atmospheric conditions, while climate represents the long-term average weather patterns observed in a specific area.

3. Phosphorus represents only 1% of human body weight. However, it is a building
block of very important macromolecules. Describe some of the cellular functions
that would not be possible without phosphorus.
Answer:
It would be impossible to store and transfer genetic information
It would be impossible to carry out majority of cellular activities due to lack of usable energy.
Explanation:
Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.
- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.
- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.
difference between diffusion and osmosis
Answer: In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
Explanation:
how new technology and experimental methods can lead to changes in theories.
Answer:
New findings and new evidence about a scientific theory can change the aspects of this scientific theory and in some cases, it can be proved as wrong or can be supported by more strong evidence that can prove its liability.
New technology allows scientists and researchers to study various untouched aspects and leads to find new evidence to support or prove the theory can be either change or unproven.
Thus, new technology and experimental methods can lead to changes in theories.
Is this picture below a compound or an element?
Age structure diagrams show the distribution of people of various ages. The diagrams also show the number of people in the prereproductive, reproductive, and postreproductive years. Research and note what else you can infer from age structure diagrams.
Answer:
Age structure diagrams show the following.
The height of the graph indicates life expectancy.
The width of the base shows birth and fertility rate.
The slope of the pyramid-shaped diagram indicates death rate.
Bends in the graph indicate reductions in birth rate or increases in
death rate.
The overall shape of the diagram indicates whether it is an economically developed country or not.
Explanation:
In a stable human population, the age structure diagram looks like a pyramid with a narrower base. The narrower base depicts that the birth rate is low. A stable human population also has a high number of older individuals. A greater number of older people in a population shows that quality of life is high in that area/country and the population has access to nutritional diet, medical care, and healthcare services. These features of the age pyramid in a stable population indicate a developed country. Age pyramids of underdeveloped countries have a wider base (high birth rate) and narrow tip.

What is the endocrine system?
A group of organs called glands makes up your endocrine system. These glands, which may be found all over your body, produce and emit hormones.
Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily activities. These messages instruct your body on what to do and when.
The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking them into the cells they intend to reach.
When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormones when levels fall below a specific threshold. Homeostasis is a mechanism that functions similarly to your home's thermostat. Almost every process in your body is impacted by hormones.
Therefore, it is like the scenario where a message is shown to a friend who shows it to another person.

Which of these organisms does NOT produce an enterotoxin?
a. Shigella spp.
b. Clostridium botulinum.
c. Vibrio cholerae.
d. Staphylococcus aureus.
Answer:
b. Clostridium botulinum.
Explanation:
The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells Moreover, Clostridium botulinum is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.
The organism that does NOT produce an enterotoxin among the options given is b) Clostridium botulinum. Clostridium botulinum is a bacterium known for producing botulinum toxin, which is a neurotoxin rather than an enterotoxin. It does not, however, create an enterotoxin.
The severe sickness known as botulism is brought on by the botulinum toxin, which predominantly affects the nervous system.
Although enterotoxins can induce diarrheal disorders and are linked to gastrointestinal symptoms, an organism need not produce an enterotoxin to be pathogenic. The host's sensitivity to infection and the infectious dosage are other important variables.
