Answer:

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

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.

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

Upper and Lower motor neurons, and Voluntary muscles.

Explanation:

Structurally,the  motor neurons in the Brain are called the upper motor neurons.While the motor neurons  in the spinal cord and the brain Nuclei  are called the lower motor motor neurons.

Therefore,  transmission of sensory impulses  from the  brain  through the upper motor neuron   are sent to the spinal cord through the lower motor neurons.  These are eventually sent to the muscles(voluntary muscles)  the effectors to bring response.

However, in ALS both the upper and lower motor neurons degenerate and die.Therefore  transmission of action potential is impeded.Thus the voluntary muscles are made redundant with no sensory information and therefore they twitch (this is called fasciculations) and progressively undergo waste away.

As this progress the ability of the brain to initiate action potential for sensory information and its propagation is lost.

Therefore weakness of muscles and stiffness results,followed by complete loss of sensory transmission and inability of the individual to respond to sensory stimulus of walking, standing, eating, and breathing.Slurred and nasal speech,and muscles cramps are other symptoms

At advanced stage loss of life usually results from the respiratory failure.

it occurs mostly in the  Caucasians and non-Hispanics between the age of 55-75,and common in males than females.It causes are blend of genetic and environmental factors.

Medication,therapy-physical and speech therapy are some means of treatments.

Carbon dioxide is produced in a cement plant when limestone is decomposed.

Cement is produced using lime stone as raw material. The limestone is decomposed according to the reaction;

CaCO3(s) -----> CaO(s) + CO2(g)

The CaO is used to produce cement while CO2 is a waste gas that escapes.

Hence, carbon dioxide is  produced in a cement plant limestone is decomposed.

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.

Explanation: Hope this helps. I did copy it from another website so if ur going to use it make sure to reword it:)

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.

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.
