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.

Answer: signals fair weather and an approaching cold front
A student notices cirrus clouds characterized by long, thin, wispy strands of clouds in the sky. It generally appears white or light grey in color and signals fair weather and an approaching rain or cold front.
Answer: Oxygen consumption within the mitochondria will decrease further
Explanation:
If the NDU gene is amplified inside cells leading to overexpression of the protein, the event that is likely to occur under hypoxic conditions is Oxygen consumption within the mitochondria will decrease further
1. Rhythm generators (SA node)
2. Conductive cells (node cells)
3. Contractile cells (myocardial cells)
Answer:
A) Biotic
Explanation:
It's definitely not abiotic and nonliving because they are living and who would categorized 'excretions of living organism' "living".
