A) ocean currents is correct

Explanation:

El Niño is caused by ocean currents. So, the correct option is (A).

An ocean current is a type of continuous, directed movement of ocean water that is generated by a number of forces acting on the water including wind, the Coriolis effect, breaking waves, cabling, and temperature and salinity differences.

These can be caused by density differences in air, water masses that occur due to temperature and salinity variations, gravity, and events such as earthquakes or storms. These are continuous streams of sea water that spread through the ocean.

An El Niño condition typically occurs when surface waters in the equatorial Pacific become warmer than average and easterly winds become weaker than normal.

Thus, El Niño is caused by ocean currents. So, the correct option is (A).

Mendel's principle of independent assortment states that during the formation of gametes, the alleles for different traits segregate or assort independently of one another. This means that the inheritance of one trait does not affect the inheritance of another trait. In other words, the alleles for different traits are sorted into gametes randomly and independently.

Mendel's Principle 1 & 2 Mendel's Law I Mendel's Law I, also known as the Law of Segregation, states, 'on the formation of gametes the two genes which are pairs will be separated in two daughter cells'. This law applies to monohybrid crosses (crosses with one different trait). Mendel's law 1 is called the law of gene separation or the law of segression which states that one of two gene alleles will separate during the process of forming offspring gametes. Mendel's law is a law of heredity which describes the principles of inheritance in organisms. Mendel's law 1 (free segregation) reads "when gamete formation takes place, 2 paired genes will be separated into 2 cells or gametes independently".

The statement that is true about the forelimbs of penguins, alligators, bats, and humans is that they have similar bone structure, implying a common ancestor.

These four animals have forelimbs that are adapted for different functions, such as swimming, flying, walking, and grasping, but they all share a basic bone structure that is similar in form. This suggests that they have evolved from a common ancestor with a similar forelimb structure that has been modified over time to suit their different needs.

This similarity in structure is known as homology, and it is considered strong evidence of evolution by common descent. Homologous structures are features that have the same basic structure and origin, but have been modified in different ways to perform different functions in different species.

Explanation:

Whilst Earth's tectonic plates grind past one another, massive quantities of power may be launched in the shape of earthquakes. Volcanoes are also often found close to plate limitations because molten rock from deep within Earth—known as magma—can tour upward at those intersections between plates.

Plate tectonics is a scientific principle that explains how major landforms are created due to Earth's subterranean movements. The theory, which solidified within the 1960s, converted the earth sciences by using explaining many phenomena, which include mountain constructing activities, volcanoes, and earthquakes.

Plate motions motivate mountains to rise in which plates push together, or converge, continents to fracture and oceans to shape wherein plates pull aside or diverge. The continents are embedded inside the plates and go with the flow passively with them, which over thousands and thousands of years effects in enormous changes in Earth's geography.

Researchers now believe that most elderly people retain their intellectual abilities throughout life.

The correct answer D.

Declining mental abilities are part of the aging process of an organism in general, most studies show that after reaching a peak between the ages of 45-55 years, most of a person's abilities continuously decline, this also applies to an elderly person.

While aging reveals diminishing intellectual decline, the decline also tends to affect certain memory limitations.

The intellectual decline of the elderly is generally something that cannot be avoided, caused by various factors, such as illness, anxiety, or depression. But the intellectual abilities of the elderly can be maintained. One of the factors to be able to maintain this condition is to provide an environment that can stimulate or train their intellectual skills and can anticipate the occurrence of senility.

During the process of photosynthesis, solar energy is converted into chemical energy to build carbohydrates.

Plants and other living things utilize a process called photosynthesis to transform solar energy into chemical energy that can then be released through cellular respiration to power the organism's activities.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose in this process.

If excitatory neurotransmitters in the synaptic cleft have not been degraded, the postsynaptic neuron would continue to be stimulated.

This is because the neurotransmitters will continue to bind to the postsynaptic receptors, causing a depolarization of the postsynaptic membrane.

This depolarization would result in an inflow of sodium ions and an outflow of potassium ions into the neuron.

An excitatory postsynaptic potential would follow from this increase in the depolarization of the postsynaptic membrane caused by the inflow of sodium ions (EPSP).

After that, the EPSP would be combined with EPSPs from other neurons, and if the action potential threshold is achieved, an action potential would be produced, stimulating the postsynaptic neuron.

The neuron would be constantly stimulated if the neurotransmitters weren't broken down, which might eventually cause weariness and death.

Fertilisers give crops vital nutrients like nitrogen so they may grow larger, more quickly, and yield more food.

However, using too much fertiliser can be harmful because it causes eutrophication and the emission of greenhouse gases.

Potassium (K)-rich fertilisers are regularly used to make up for plant deficiencies. Farmers must add this essential plant nutrient when soils are unable to provide crops with the K levels they require.When urea is added to the soil, it quickly turns into ammonium through a reaction with water and the soil enzyme urease.

The chemical reaction below illustrates this conversion, which is known as urea hydrolysis. The consumption of hydrogen ions (H+) in this reaction raises the pH of the soil close to the fertiliser.
