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.

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.

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.

There 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.

The 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.

Geothermal energy is also used in industries for cooking, pastuerizing milk etc.

Answer:

a. ribosomes

Explanation:

Answer:

The third line of defense is specific resistance. This system relies on antigens, which are specific substances found in foreign microbes. Most antigens are proteins that serve as the stimulus to produce an immune response. ... The activation of T-cells by a specific antigen is called cell-mediated immunity.

In El Niño years, the prevailing winds that normally drive a warm current from the Equator past New Zealand are disrupted and may stop or even reverse.

The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels.

Explanation:

-Venom are complex mixtures of molecules called "toxins"

-Plasma membrane is the membrane found in cells that separates the interior of the cell from the outside environment

Answer:

A

Explanation: The membrane acts like a shield for the cell to keep it safe. A plant cell has a cell membrane AND a cell wall but an animal cell ONLY has a cell membrane. It also filters what can go in and out of the cell. Hope this helps(:

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.

With respect to other options:

A

Explanation:

A

Explanation:

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.

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.

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.

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.

Dihybrid cross

Explanation:

Whereas a monohybrid cross is a cross between two organisms that differ in a single trait, a dihybrid cross follows two traits.

It describes a mating experiment  in which the phenotypes of two genes are followed through to the offspring in order to study the inheritance at those genes

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.

Answer:

Absence of a nucleus

Explanation:

In eukaryotic cells, DNA is typically harvested and saved in the nucleus, though prokaryotic cells lack a nucleus, so the DNA merely floats in the cytoplasm instead.

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.

Answer:

controlled variables

Explanation:

Controlled variables are ones that could affect the experiment, and the scientist keeps them the same to make it fair.
