(A) Light → Sunshine recorder

The fundamental equation for wave motion is: This is a standard relationship in the context of electromagnetic waves, where is the speed of light, is the wavelength, and (or ) is the frequency.

Mitochondria are known as the "power house" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.

In acrocentric chromosomes, the centromere is located near one end, resulting in a very short (p) arm and a very long (q) arm.

Amoeba is a unicellular eukaryotic organism that lacks cell walls and belongs to the kingdom Protista. Members of this kingdom are mostly unicellular and show both plant-like and animal-like characteristics.

This is a test cross, where an organism heterozygous for two traits (AaBb) is crossed with one that is homozygous recessive for both traits (aabb).
Parent 1 genotype: AaBb
Parent 2 genotype: aabb Gametes from AaBb: Since AaBb is heterozygous for both traits, it can produce 4 types of gametes: Gametes from aabb: Since aabb is homozygous recessive, it can produce only 1 type of gamete: F\textsubscript{1 Generation Offspring:} Crossing the above gametes gives 4 possible combinations: \begin{tabular}{ll} AB × ab & AaBb
Ab × ab & Aabb
aB × ab & aaBb
ab × ab & aabb
\end{tabular} Each genotype corresponds to a unique phenotype:
AaBb: dominant for both traits
Aabb: dominant for first, recessive for second
aaBb: recessive for first, dominant for second
aabb: recessive for both traits Thus, the phenotypic ratio =
