Answer:
The correct answer is b. melanin
Explanation:
The various pigments and nutrients which are found in a cell but are not organelle because they do not perform activities like organelle perform are called cell inclusions. Some of the examples of cell inclusions are lipids, melanin, lipids, etc.
Therefore melanin is considered as inclusion. Melanin is produced by specialized cells called melanocytes from where it gets transported to skin and hair which provided the skin and hair its color. Therefore the right answer is melanin.
Melanin is an inclusion, not an organelle.
An organelle is a specialized structure within a cell that performs specific functions. Based on the options given, melanin is an inclusion, not an organelle.
Melanin is a pigment found in the skin, hair, and eyes, responsible for color. It is not a specialized structure within a cell like lysosome, cilia, and microtubule, which are all organelles.
In conclusion, the correct answer is melanin.

A mutation changes the sequence of RNA bases in a gene.
B.
A mutation creates the sequence of RNA bases in a gene.
C.
A mutation changes the sequence of DNA bases in a gene.
D.
A mutation creates the sequence of traits in a gene.
Process 2 is known as transcription. Hence the correct option is c.
Transcription is a fundamental process in molecular biology that involves the synthesis of RNA (ribonucleic acid) using a DNA (deoxyribonucleic acid) template. This process plays a crucial role in the transfer of genetic information from theDNA to RNA, which is then utilized in the synthesis of proteins. Transcription is a multi-step process that can be divided into three main stages: initiation, elongation, and termination.
Transcription begins with the binding of an enzyme called RNA polymerase to a specific region of the DNA known as the promoter. The promoter serves as a signal for the start of transcription and provides the necessary binding site for RNA polymerase. Once the RNA polymerase is bound, it unwinds the DNA double helix to expose the template strand.
Transcription is a vital step in the central dogma of molecular biology, converting genetic information encoded in DNA into RNA. The resulting RNA molecules, such as messenger RNA (mRNA), serve as templates for protein synthesis during translation. This intricate process is tightly regulated to ensure accurate transmission of genetic information and the production of functional proteins essential for cellular functions.

B. copper and iron.
C. zinc and magnesium.
D. iron and zinc.
Answer:
Option A
Explanation:
The core of earth has two parts
a) Outer core – The outer core is made up of molten alloy of iron and nickel. However, it also has traces of dense materials like gold, platinum, and uranium etc. These materials are contained at a very high temperature i.e 9,000 and 13,000 degrees Fahrenheit.
b) Inner Core – It is composed of solid dense iron but the iron is not in its purest form. It has some impurities such as sulfur etc. It has temperature ranging between 7000 to 9000 degrees Fahrenheit and is responsible for earth's magnetic field.
Hence, option A is correct
