Explanation

 A NiCad (Nickel-Cadmium) battery has a nickel oxide hydroxide (NiO2) cathode and a cadmium anode. 

Explanation

 As a reaction proceeds, the rate of reaction decreases because the concentration of reactants decreases, leading to fewer collisions and slower reaction. 

Explanation

 Human tissues, particularly in organs like the brain and kidneys, can contain approximately 85% water.

The exact percentage varies by tissue type, but many, especially soft tissues, are largely composed of water.

Explanation

 The Calvin cycle is also known as the C3 cycle or the light-independent reactions of photosynthesis.

It can also be referred to as the Calvin-Benson cycle or the reductive pentose phosphate cycle (RPP cycle). 

Explanation

  Cohesion refers to the attraction between water molecules due to their polar nature, allowing them to "stick" together. 

Explanation

The ecological role of fungi as decomposers is primarily paralleled by bacteria.

Both fungi and bacteria are essential decomposers in ecosystems,

Breaking down dead organic matter and releasing nutrients back into the environment.

While fungi are known for their ability to decompose complex organic materials like cellulose and lignin

Bacteria also play a crucial role in breaking down a wide range of substances.

Together, they form the core of the decomposition process,

Which is vital for nutrient cycling and maintaining ecosystem health

Explanation

Spiral cleavage is characterized by diagonal cleavage planes that are not symmetrical between the poles, resulting in unequal blastomeres arranged in a spiral pattern.

Determinate cleavage means that the fate of each blastomere is predetermined early on, meaning each cell has a specific developmental role. 

Explanation

This formula comes from the Rayleigh criterion for the minimum resolvable angle (θₘᵢₙ) in optical systems like lenses or telescopes:

$$theta_{min} = frac{1.22 , lambda}{D}$$

Where:

• $lambda$ = wavelength of light

• $D$= diameter of the lens aperture

This equation gives the angular resolution or resolving power of the lens.

Explanation

The general formula for rotational kinetic energy is:

K.E.=1​/2Iω^2

Where:

• $I$= moment of inertia

• $omega$ = angular velocity

For a hoop (thin ring) of mass
$m$ and radius r:

$I=mr^2$

So, plugging into the formula:

K.E.=1/2⋅mr^2 ⋅ω^2= 1/2​Iω2

Explanation

 With a temperature rise, the velocity of sound increases.

This is because warmer temperatures cause molecules to move faster, allowing sound waves to propagate more quickly through the medium

Specifically, the speed of sound is directly proportional to the square root of the absolute temperature.

For every degree Celsius increase in temperature, the speed of sound in air increases by approximately 0.6 m/s
