Explanation

The given compound is an ionic compound

It is made up of:

• one potassium
• one manganese,
• four oxygen atoms.

Oxidation numbers of potassium (K) and oxygen (O) are +1 and -2 respectively.

Let us assume that the oxidation number of Mn is $x$.

Since ionic compounds are neutral, the net charge on them is zero.

(Oxidation number of K) + (Oxidation number of Mn) + (4 $\times$ The oxidation number of O) = $0$

(1)$\times$(K) + (1)$\times$(Mn) + 4$\times$(O) = $0$

$(1)$$\times$(+1) + (1)$\times$($x$) + 4$\times$(-2) = $0$

$x$ = +7

Hence, the oxidation number of $\text{Mn}$ in ${\text{KMnO}}_4$ is +7.

Explanation

An enzyme changes shape to fit the substrate.

• The enzyme's active site is flexible, not rigid
• The enzyme changes conformation when the substrate binds
• Like a hand fitting a glove
• Differs from the fixed lock-and-key model

Explanation

Stainless steel is a alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties.

Explanation

Horticulture is the study and practice of cultivating fruits, vegetables, flowers, and ornamental plants.

Including the design and management of gardens.

Explanation

Gamma rays are the highest energy photons, with energies typically above 100,000 electronvolts (eV).

They are a type of electromagnetic radiation, like X-rays and visible light, but with much shorter wavelengths and higher frequencies.

Explanation

A pinhole camera works without lenses.

It uses a small aperture (pinhole) to project an inverted image of the scene onto the opposite surface.

Explanation

The lungs are located on either side of the breastbone in the chest cavity 

Explanation

Due to biomagnification, DDT (Dichlorodiphenyltrichloroethane) accumulates more in organisms higher up the food chain. 

Seagulls, being top predators, experience the highest deposition of DDT.
