Answer:
The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".
Explanation:
In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

how do amphibians breathe on land and in water
Answers
Answer:
Most amphibians can breathe both through cutaneous respiration (through their skin) and buccal pumping - though some also retain gills as adults. Some aquatic salamanders (and all tadpoles) have gills and can breathe underwater thanks to them. The Mexican axolotl, for example, never loses its gills.
TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms
Answers
Answer:
Protozoa
Explanation:
The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.
Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.
Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.
Hence, the case of Mr. L would be that of protozoa.

Which of the following stages of the water cycle is most likely to be occurring on a clear, sunny, hot day?
OA. evaporation
OB. precipitation
OC. condensation
OD. surface runoff
Reset
Submit
Answers
Evaporation occurs when water changes from a liquid to a gas (water vapor) and enters the atmosphere. On a clear, sunny, hot day, the sun's heat causes water on the surface of bodies of water, such as oceans, lakes, and rivers, to evaporate and enter the atmosphere. This process is also called solar radiation because it is driven by the sun's energy.
During evaporation, water molecules absorb energy from the sun, which causes them to move more quickly and break free of their bonds with other water molecules. As the water molecules gain enough energy, they escape into the atmosphere as water vapor. Once in the atmosphere, water vapor can travel long distances and participate in other stages of the water cycle, such as condensation and precipitation.
Overall, a clear, sunny, hot day is ideal for evaporation to occur because it provides the heat needed to drive the evaporation process.

What is Inheritance?
Genetic information from one parent to another is passed down through heredity.
The DNA (deoxyribonucleic acid) found in the sex cells transmits information as chemical codes.
By virtue of chromosomal variation, inheritance occurs.
Chromosomes are the inheritance units that carry genetic material.
In sexual reproduction, each gamete of the opposing sex participates, providing traits in the form of genetic material.
Hemophilia and other genetic illnesses are examples of inheritance.
The next generation inherits the traits that are expressed in the offspring. Inherited qualities are those that are passed down from one generation to the next.
An individual acquires acquired qualities over the course of their lives. These develop in the body's somatic cells as a result of alterations in lifestyle, the loss or misuse of bodily parts, injuries, etc. The following generation does not inherit these modifications.

Answers
The particles of the substance initially had high Kinetic Energy.
Does the kinetic energy of a particle change as the temperature changes?Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.
In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

Give two examples of how homeostasis helps regulate the human body.
Answers
Answer:
Here are two examples of how homeostasis regulates different aspects of the body: Get homework help from firstgradeessays[at]gm ail. c om. Quality is a priority.
Body Temperature Regulation: The human body has a set temperature range (around 36-37 degrees Celsius or 98-99 degrees Fahrenheit) that needs to be maintained for optimal functioning. When the body temperature rises due to exercise or external heat, homeostatic mechanisms helps to cool the body. These mechanisms include sweating, which helps dissipate heat through evaporation. Dilation of blood vessels near the skin surface facilitates heat loss. Conversely, if body temperature drops, homeostatic responses like shivering and constriction of blood vessels occur to generate heat and conserve warmth.
Blood Glucose Regulation: Maintaining blood glucose levels within a narrow range is crucial for proper physiological functioning. After a meal, blood glucose levels increase, triggering the release of insulin from the pancreas. Insulin helps facilitate the uptake of glucose by cells, reducing blood glucose levels back to normal. On the other hand, when blood glucose levels drop (e.g., during fasting or exercise), the pancreas releases glucagon, which stimulates the liver to release stored glucose into the bloodstream. This process raises the blood glucose levels and restores homeostasis.

Suppose rising sea levels again separate the continents of North and South America. Choose one of Earth's spheres, and explain how it might interact differently with another of Earth's spheres because of this change.
Answers
The separation of North and South America by rising sea levels would result in changes in the interaction between the biosphere and the hydrosphere. Disrupted migration patterns, altered nutrient distribution, and changes in habitat availability would affect the biodiversity and ecological dynamics in the marine ecosystem.
If rising sea levels were to separate the continents of North and South America, one sphere that would interact differently with another sphere is the biosphere and the hydrosphere.
The biosphere refers to all living organisms and their interactions with the environment, while the hydrosphere encompasses all water bodies on Earth, including oceans, lakes, rivers, and groundwater. The separation of North and South America by rising sea levels would result in significant changes in the distribution and connectivity of marine habitats, impacting the biodiversity and ecological dynamics in both spheres.
With the separation of the continents, marine species that depend on migratory patterns, such as marine mammals, fish, and sea turtles, may face challenges in their natural movement and breeding cycles. Disrupted migration routes and barriers created by the rising sea levels could lead to isolation or fragmentation of populations, affecting their genetic diversity and long-term survival.
Furthermore, the change in the physical geography due to the separation could alter oceanic currents and water circulation patterns. This, in turn, would affect nutrient distribution and primary productivity in the water column, influencing the food webs and species interactions within the marine ecosystem. The availability of specific habitats, such as coastal wetlands and coral reefs, could also be affected, impacting the biodiversity and ecological services they provide.
