Autism Spectrum Disorder is a type of intellectual disability.

• The autism spectrum or autistic spectrum describes a range of conditions classified as pervasive developmental disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM). 
• The term "autism spectrum" is often used to describe disorders that are currently classified as pervasive developmental disorders.
• The pervasive developmental disorders include autism, Asperger syndrome, Childhood disintegrative disorder, Rett syndrome and Pervasive Developmental Disorder Not Otherwise Specified.
• These disorders are typically characterized by social deficits, communication difficulties, stereotyped or repetitive behaviors and interests, and/or cognitive delays.
• Although these diagnoses share some common features, individuals with these disorders are thought to be "on the spectrum" because of differences in severity across these domains.

Therefore, we can conclude that Autism Spectrum Disorder is a type of intellectual disability.

Critical pedagogy includes relationships between teaching and learning. Its proponents claim that it is a continuous process of what they call unlearning, learning, and relearning, reflection, evaluation, and the impact that these actions have on students. Critical pedagogy is a philosophy of education and social movement that combines education with critical theory. Paulo Freire was the first to describe it.
Freire endorses students' ability to think critically about their educational situation; this way of thinking allows them to recognize connections between their individual problems and experiences and the social contexts in which they are embedded.

Learning disability refers to a neurological disorder that causes cognitive impairment. Reading disorders are part of learning disabilities.

Gender discrimination may lead to diminished effort or performance in education or the labour market, which itself gives rise to negative outcomes. What remains unclear from this line of research, however, is to what extent perceptions of discrimination correspond to some reliable depiction of reality. Because events may be misperceived or overlooked, perceptions of discrimination may over- or under-estimate the actual incidence of discrimination.

A picture will be the best teaching aid to teach the subject of biology. A number of pictures can be used to teach each of the processes individually.

Transition elements belong to d block and the first transition elements is scandium(whose atomic no. is 21)

+3 charge means no of electrons will be 3 less than no. of protons. So no. of protons will be 21. So atomic no. is 21.

In [Ni(CO)₄]
Let the oxidation state of Ni is x.
x + 4 x (0) = 0 (Carbonyl (CO) is a neutral ligand and have zero charge.)
x = 0
Hence, Ni have zero oxidation state.

Eka aluminum predicted by Mendeleev is Gallium.

Eka-aluminum and gallium are two names for the same element, as Eka-Aluminium has almost identical properties to the gallium element itself.

Additional information: Mendeleev names unnamed elements as EKA- Boron EKA- Aluminium and EKA Silicon which were later replaced as Scandium, Gallium, and germanium respectively.

• Eka boron is The element Scandium.
• Eka aluminum is the element Gallium.
• Eka silicon is the element Germanium.

1 mole = 6.023 × 10²³ atoms / molecules = X
1 mole = Molar volume =22.4 L at NTP = Y
1 mole = Gram atomic mass or gram molecular mass = Z
Hence, option B is correct.

Ambidentate Ligand: Nitro

• An ambidentate ligand is a type of polydentate ligand that can bind to a central atom in multiple ways because it has two or more donor atoms, but uses only one of them in forming a coordinate bond at a time.
• Nitro (NO^2-) is an example of an ambidentate ligand. It can coordinate to the central metal atom either through the nitrogen atom (forming a nitro complex) or through one of the oxygen atoms (forming a nitrito complex).
• The other options provided do not have this property. Oxalate is a bidentate ligand, meaning it simultaneously uses both of its oxygen atoms to bind to the central atom. Carbonyl is a monodentate ligand, it can only bind through the carbon atom of the C=O group. Acetate is also a monodentate ligand, it can only bind through the oxygen atom of the C=O group.

Therefore, among the given options, only Nitro is an ambidentate ligand.

[Ni(CN)₄]^2- in this, Ni has dsp² hybridisation with square planar geometry and it is diamagnetic.

Position of the p^th dark fringe is at a distance of 
y=(2p−1) (λD/2d)​ from the centre
where 
λ: Wavelength
D: Distance between slits 
d: slit width

Area of square card = 1 mm × 1 mm = 1 mm²
Focal length of magnifying lens, f = +10 cm
Object distance, u = -9 cm
According to thin lens formula

or v = -90 cm

∴ Apparent area of the card through the  lens 
= 10 × 10 × 1 mm²
 = 100 mm²
 = 1 cm²

3. 1.5

Solution: Let the radius of curvature of the convex surface of the plano-convex lens be RRR. The focal length of a concave mirror is related to the radius of curvature by f=R2f = \frac{R}{2}f=2R​.

1. When the plane side is silvered, the system behaves as a concave mirror with focal length 30 cm. The effective focal length fefff_{\text{eff}}feff​ of this system can be found using the mirror formula and lens formula combined, but given the scenario, we focus on this system.

2. When the convex side is silvered, the system behaves like a concave mirror with focal length 10 cm.

By using the relations for combined focal length and refractive index of the plano-convex lens, and applying these boundary conditions, the refractive index nnn of the material of the lens is determined to be 1.5.

α (Radian)=10/2000=1/200rad
α=h/F=h/1.2
h= α x 1.2
h=(1/200) x1.2 cm
=6mm

For real object and real Image,
(1/v)+(1/u)=(1/f)=> -(1/v)-(1/u)=-(1/f)
(1/v)+(1/u)=(1/f) => 1/v=-(1/u)+(1/f)
y=mx+c
The correct answer is option B.

It is true only for an infinitely long solenoid.
Magnetic field at any point is the summation of magnetic fields produced by each turn of the wire of the solenoid.
Now imagine a solenoid in front of you stretching to infinity on both the sides, say from left to right. An infinitely long solenoid has no ends and the field everywhere inside it is the same and let its intensity be E. Now cut the solenoid at a point in front of you and throw (!) the half away. You now have in front of you, an end of the remaining half. The field at this end is now due to half the total turns and hence it is E/2.
 

The transpose of the given column matrix is a row matrix with the same elements in the same order. So, the transpose of the given matrix is ([4, -1, 2]), which matches option B.

Variance is the mean of the squares of the deviations from the mean. Variance is the square of standard deviation. Therefore any unit of a given set is converted into squares at the time of calculating the variance.

Given: y = sin 3x . sin³

= 3 sin²x.sin 4x

If A and B are symmetric matrices of the same order, then , AB + BA is always a symmetric matrix.

y = sec⁻¹ x
by rewriting in terms of secant,
⇒ secy = x
by differentiating with respect to x,
⇒ secy tany y'= 1 by dividing by secy tany,
⇒ y'= 1/secy tany
since secy = x and tanx = √sec²y − 1 = √x²−1
⇒ y'= 1/x√x²−1
Hence, d/dx(sec⁻¹x) = 1/x√x²−1

If A = [a_ij]_2x2 where a_ij = i + j, then, 

Let x' and y' be the reflection of x and y, therefore :



Hence, reflection is on the line - x-y = 0⇒ x + y = 0

f(x) = x^x     f(x) = x^(-x)
f’(x) = x^x(1+ln x)          f’(x) = -x^(-x)(1+ln x)
1+ln x = 0                   x = 1/e
x = 1/e
Min value = (1/e)^(1/e)        f(1/e) = e^(1/e)
Product = (e^-1/e)(e)^1/e = 1

Pierre de Coubertin proposed the Olympic motto "Citius, Altius, Fortius", which is Latin for "Faster, Higher, Stronger".

The 1750 MW Lower Demwe Hydro Electric Project is being constructed on Lohit River jointly by Athena Energy Ventures and the Arunachal Pradesh government. Lohit is one of three rivers that meet to form the Brahmaputra in Assam downstream.
