A. Secondary succession occurs in ecosystem that have no vegetation.
What is secondary succession?
"Secondary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity."
What are the stages of secondary succession?
The stages that lead to secondary succession include:
Growth exists.Existing growth is destroyed.Destruction stops. The soil remains.Time goes by.Regrowth begins.Fast-growing plants and/or trees are dominant for a while.Slower growing plants and/or trees come back and begin growing.Eventually, the area is fully populated with plant life again, though it may be more diverse or otherwise different than it was prior to being destroyed.What is an ecosystem?
"An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life."
What is a vegetation?
"Vegetation is defined as growing plants, or a life without physical, mental or social activity."

Can convection take place in the water if it is heated at the top?
Answers
Answer: If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then the unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.
This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.

The following are examples of seed dispersal: A crow eats blackberries from a bush, a wave carries a coconut out to sea, and a wolf picks up burrs on its fur that are preset in options A, B, and D.
What is seed dispersal?Seed dispersal is the movement of seeds from the parent plant to a new location, and this can be done by many, such as when a crow eats blackberries from a bush; that is an example of endo zoochory, where animals consume the fruits or berries of a plant and the seeds pass through their digestive system. A wave that carries a coconut out to sea is an example of hydrochory, where seeds or fruits are dispersed by water, and a wolf that picks up burrs on its fur is an example of epizoochory and in these ways seed dispersal occurs.
Hence, examples are A crow eats blackberries from a bush, a wave carries a coconut out to sea, and a wolf picks up burrs on its fur that are preset in options A, B, and D.

Answers
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.

Compare and contrast between seed plants and seedless plants:
Dominant generation:
Long distance of dispersal:
Answers
Answer:
seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication.
Explanation:
The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication. The plant kingdom is traditionally divided into four main divisions, i.e Thallophyta, Bryophyta, Pteridophyta and Spermatophyta
The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
In many plants, the sporophyte generation is the dominant generation. This means that the sporophyte is larger and lives longer than the gametophyte generation.

You are studying transplant rejection in a wild and genetically diverse population of mice. You have captured some of the mice for laboratory studies. You have four mice from a family. Mouse 1, mouse 2, and mouse 3 are littermates, thus they all share the same mother and father. Mouse 4 is the father of the other three mice. You transplant a small patch of skin from mouse 2 (the donor) onto mouse 1 (the recipient). There is a delayed inflammatory response and two weeks later the skin is necrotic due to transplant rejection. You decide to attempt another transplant. Which follow-up transplant is LEAST likely to be rejected?
a. skin from mouse 1
b. skin from mouse 2
c. skin from mouse 3
d. skin from mouse 4-incorrect
Answers
Answer:
b. skin from mouse 2
Explanation:
According to this question, a mice skin transplant is being conducted. Four mice labelled Mouse 1, Mouse 2, Mouse 3 and Mouse 4 are used for this experiment. A small patch of skin from mouse 2 (the donor) was transplanted onto mouse 1 (the recipient), however, it was eventually rejected by the recipient (mouse 1).
This transplant rejection is due to the fact that the recipient's immune system identifies the tansplanted skin as foreign, hence, begins to attack it, leading to the skin's necrosis or death. Based on this, the same transplant rejection will occur if skin patches from mouse 3 and 4 are used.
However, the immune system of mouse 1, which is the recipient, will identify skin patches from MOUSE 2 as less foreign than any other skin from other mice. This is because skin from that mouse has been used before, hence, the recipient's immune recognizes it when a follow-up transplant is conducted. This makes a follow-up transplant from MOUSE 2 be the least likely to be rejected.

Renewable resources are those resources which are inexhaustible in nature . It means these resourses are present in unlimited quantity and are environment friendly.
Geothermal energy is one of the example of renewable resources.
In geothermal energy, The word ' geo' stands for earth. So ,It basically means the energy that is extracted from the earth.
Here are some uses for the utilisation of renewable geothermal energy.
Geothermal energy helps in generating electricity.The geothermal power plant extract the heat from geothermal reservoirs. Then, This extracted heat is transfer to the heat engine .Which are responsible for running the heat engine smoothly and generation of electricity.
Geothermal energy helps in heating greenhouse .The heat that is released from the underground reservoirs are used to reduce green house gases because Geothermal energy needs very less CO2 . This heat is transfer in green house and it results into direct heating of green houses.
It also act as a tourist spotThere are so many people who wish to enjoy their leisure time peacefully. In winters, People like to visit the areas where hot spots are found .Which is a example of geothermal energy.
Geothermal energy helps in heating and cooling buildingsThe warm water is taken from underground reservoirs and then converted into hear energy. Then this heat energy is transfer in the building by using geothemal pumps helps in generating heat in building in winter. This same process is also follows for cooling of building.
It is also used as industrial purposeGeothermal energy is also used in industries for cooking, pastuerizing milk etc.
Explain the mechanism maintaining osmotic gradient in renal medullary intestitium
Answers
In the inner medulla, urea recirculates, creating a greater osmotic gradient. It follows the concentration gradient formed by ADH-sensitive water reabsorption into the interstitial space from the collecting duct. The remaining water is drawn from the descending structures by increased interstitial osmolarity.
To maintain the vertical osmotic gradient, the blood supply to the renal medulla serves as a countercurrent exchanger. - The medullary vertical osmotic gradient is maintained by the vasa recta.
It enhances both water and urea permeability in the inner medullary collecting ducts, allowing urea to diffuse passively down its concentration gradient into the interstitial fluid. This contributes to the osmotic gradient and aids water absorption.
