If a gene is found only on the X chromosome and not the Y chromosome, it is
said to be a sex-linked trait. Because the
gene controlling the trait is located on the sex chromosome, sex linkage is
linked to the gender of the individual. Usually such genes are found on the
X chromosome. The Y chromosome is thus missing such genes (See Diagram above.).
The result is that females will have two copies of the sex-linked gene while
males will only have one copy of this gene. If the gene is recessive, then males
only need one such recessive gene to have a sex-linked trait rather than the
customary two recessive genes for traits that are not sex-linked. This is why
males exhibit some traits more frequently than females.

The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

Answer:
as the question is incomplete i have added the link to full question in ask for detail section.
b) Lysosome
Explanation:
After ingestion of a food particle, pH changes and enzymes contributed by the __Lysosome__ will digest and hydrolyze the ingested particle in the phagocytic vacuole.
Answer:
The correct option is d) UAG
Explanation:
Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.
The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.
