Explanation

 In Einstein's universe, the fourth dimension is time. 

Einstein's theory of relativity revolutionized our understanding of space and time, merging them into a single four-dimensional continuum called "spacetime".

Time is considered the fourth dimension within this framework. 

Explanation

Apiculture is the practice of rearing and maintaining honeybees for the production of honey, beeswax, and other bee-related products. It involves beekeeping and managing bee colonies for commercial and agricultural purposes.

• The other options refer to different types of cultivation:

• Mori culture (A) – Cultivation of mulberry plants for silkworms.

• Sericulture (B) – Rearing of silkworms for silk production.

• Silviculture (D) – Cultivation of forests and trees

Explanation

Ecotones:

Ecotones are transitional areas between different ecosystems or biomes, where there's a change in species composition and abundance. 

Beta Diversity:

Beta diversity measures the difference in species composition between different habitats or communities, which is precisely what happens at an ecotone. 

Alpha Diversity:

Alpha diversity refers to the diversity within a single habitat or community. 

Gamma Diversity:

Gamma diversity refers to the total diversity across a region or landscape. 

Explanation

Ohm × Farad is equivalent to a second (s).

This is because the unit of capacitance (Farad)

multiplied by resistance (Ohm) gives time (s),

which represents the time constant in RC circuits.

Explanation

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

A metastable state is an excited state of an atom or molecule that has a significantly longer lifetime compared to other excited states, but is still shorter than the ground state.

This means that an electron in a metastable state can stay in that state for a relatively long time before transitioning back to a lower energy level. 

Explanation

A single strand of nucleic acid tagged with a radioactive molecule is called a probe.

These probes are often used in molecular biology techniques to detect specific DNA or RNA sequences. 

Explanation

Gigantism and Dwarfism are diseases related to the growth hormone of the adenohypophysis.

Explanation

The binding energy per nucleon is highest for intermediate-sized nuclei (e.g., iron).

Both lighter and heavier nuclei have lower binding energies per nucleon compared to these intermediate nuclei.

Explanation

The vector product (cross product) of two vectors gives a vector that is perpendicular to both original vectors.

Angular momentum is a vector product of position and linear momentum vectors.
