Drought conditions in Australia is expected to happen during El Niño. The correct option is A.
What is El Niño?El Niño is the warm stage of the El Niño-Southern Oscillation, and it is affiliated with a ring of warmer ocean water that forms in the eastern and central equatorial Pacific, along with the area off South America's Pacific coast.
Because of the transition in rainfall away from the western Pacific caused by El Niño, Australian rainfall is typically reduced during winter and spring, especially in the eastern and northern parts of the continent.
Developing countries that depend on agriculture as well as fishing, notably those bordering the Pacific Ocean, are typically the most affected.
The pool of warm water in the Pacific near South America is often at its warmest around Christmas during this phase of the Oscillation.
Thus, the correct option is A.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease affecting adults (~30,000 in U.S.). It is a progressive, debilitating neuromuscular disorder that generally strikes in mid- to late-life (40-70 years) and can rapidly progress to death (3-5 years from onset). ALS is characterized by selective loss of motor neurons in spinal cord, which causes loss of skeletal muscle and weakness. Motor neurons in the largest motor units appear to be most vulnerable. Based on this, which type of motor neurons and muscle fibers would you expect to be most susceptible
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.

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.

the interactions of abiotic and biotic factors results in condition that are suitable for some oranisms but not for others?
Answer:
Abiotic factors can be extremely broad. Sunlight, air, soil, rock, minerals, water, etc. are all biotic factors. Sunlight provides energy that plants utilize to grow, which ultimately holds up the whole biotic community of an ecosystem. Air also interacts with plants, helping them grow by providing a source of carbon (CO2) and other nutrients.
In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. Just as humans mine mountains and cultivate soil, rock and soil provide resources for plants, and plants cycle the nutrients through so they (usually) end up back in the ground where they began. The water, phosphorus, nitrogen, and carbon cycles are examples of this.
Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area. Geologically, organisms create topsoil by breaking down rock layers and dying, which provides detritus with which to form new soil and return nutrients to the ground

Explain the mechanism maintaining osmotic gradient in renal medullary intestitium
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:
C. sunlight and oxygen
Explanation:
Cellular respiration is quite simply the conversion of chemical energy from oxygen into ATP in order to release waste by-products.
Oxygen is needed for this process to take place because it helps break down the necessary nutrients which will in turn generate ATP, and other processes.
Therefore, an organism needs oxygen and sunlight to undergo cellular respiration.

Can convection take place in the water if it is heated at the top?
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.
